• Before you upgrade: new Activation Code. This version reads a new, signed Activation Code, so an upgraded system needs a new code once. Until it is entered, the system runs in Demo Mode.
  • Request it before the upgrade on the Re-issue Activation Code page with your License Code and Owner Email, or afterwards on the Activate page with the Computer ID the License page shows.
  • One code per computer. Earlier versions keep their current Activation Code. See the License article.
• Before you upgrade: Network & File Access on Python scripts. A Python script that brings in data from outside EnvisionSCADA needs a setting that the upgrade does not enable.
  • Tick Network & File Access on every Python script that opens network connections, serial ports, files or databases, and on every script with an EndPoint. Without it that operation is blocked with a message naming the setting. Scripts that calculate, read the Historian database, render reports or send email run as before.
  • Such a script runs in a separate process and writes only device variables and Local variables that count as license points: External Source, Writeable or a History Source outside EnvisionSCADA. Mark as External Source in the Python Editor enables the setting on the variables a run could not write. Reading a STRING license-point variable needs it too.
  • The EnvisionSCADA databases are read-only to every script: change the configuration through the Config API or MCP. The Runtime API WriteVariable is limited to the same variables, while the gateways write Writeable Local variables as before. See the Python Scripts and Local Variables articles.
• End-User Licence Agreement version 1.9, effective 2 November 2026: a Local variable that receives data from outside EnvisionSCADA counts as a Tag, like a device variable. Calculated or internal Local variables do not. The full text is on the End-User Licence Agreement page.
• One running instance per license on a server. A second instance that starts with the Activation Code of a license already running there runs in Demo Mode and says so on its License page; it takes the license within a minute after the other stops. Each instance needs its own license, and a redundant pair runs on two servers and is not affected. See the License article.
• Multiple instances on one server: the setup installs EnvisionSCADA as one or more instances, each with its own project, databases, license, IIS site and web address, and each updated on its own.
  • An upgrade changes nothing about an existing installation: it is taken over as the instance EnvisionSCADA, keeping its project, databases, IIS site, bindings, HTTPS certificate and app pool settings. Before, every upgrade recreated the site with only the HTTP binding.
  • Its installation folder becomes the data folder of the instance, and the program moves to C:\Program Files\EnvisionSCADA\<version>, which may need an antivirus exclusion. From then on, use the setup of this or a later version on that server.
  • A new installation offers Default Installation, one instance with the demo project, or Custom Installation, where you choose the instances; each keeps its data in C:\ProgramData\EnvisionSCADA\<instance>. A new setup updates the instances you select. See the Multiple Instances article.
• License points for Local variables: a Local variable with External Source, Writeable or a History Source outside EnvisionSCADA counts as a license point, like a device variable.
  • The Local Variables page shows a License point column, and UDT Local members count the same way.
  • In this version these points are counted but not yet part of the license check. The License page shows the count, and SYSTEM.ExternalSourcePointCount holds it. If this is unexpected for your situation, contact support@omniconautomation.com. See the Local Variables and License articles.
• Two new device drivers, IEC 61850 and Omron FINS, both BETA.
  • IEC 61850 [BETA]: EnvisionSCADA connects as a client to the MMS server of an IED and reads, writes and operates its data. See the IEC61850 article.
  • Omron FINS [BETA]: communication with Omron PLCs of the CS, CJ, CP, NJ and NX series over FINS/TCP or FINS/UDP. See the Omron FINS article.
  • EtherNet/IP Generic, Beckhoff ADS, BACnet and MELSEC are no longer BETA.
• History Sources configuration page: named history sources (Script or Database) with their Module Script or Connection, History Parameters, History Query and History Reference.
  • A variable selects a source by name, the EnvisionSCADA Historian or the Project default. The upgrade turns every existing per-variable source into a named History Source, so trends read from the same place as before. See the History Sources article.
• InfluxDB 3 connections are read as well as written: a History Source of Type Database reads trends from InfluxDB 3, and the Data Grid object and Database Query read its measurements.
  • The History Query is InfluxDB SQL with @Variable, @Start and @End. InfluxDB 3 is read only, so the Data Grid lists its measurements with editing off, and Allow Database Query is available. An InfluxDB 2.x connection serves Data Forwarders as before. See the History Sources, Database Query and Data Grid articles.
• Signature Required per variable: with Part 11 compliance mode on and the Write variables marked Signature Required action selected, a write asks for an electronic signature only on the variables marked Signature Required.
  • With compliance mode on, the upgrade marks every existing variable and UDT member, so a validated system keeps signing every write; without it nothing is marked. See the Electronic Signatures article.
• Python Editor renewed, with the look of the Page Editor: a toolbar, side views, tabs for several scripts and modules, and a result panel.
  • Side views for Explorer, System Functions, Variables, History and Script Settings, a bottom panel with Problems, Output, Writes and the Run Log, completion and signature help, and checks while typing that flag unknown variable names, while True and a network or file call without Network & File Access. See the Python Scripts article.
• Preview in the Pages and Symbols panels of the Quick Menu: rest the pointer on a page or symbol name to see it as last saved, with its folder, replacers and version.
  • Pages also open faster: an editor page with the standard symbol library is about half its former size. See the Pages and Symbols Panels article.
• HTTP Compression and HTTPS Compression in Parameters, Engineering Settings: pages, scripts, stylesheets and data are sent compressed, for access over a slow link such as a VPN.
  • Both are off by default and apply at once, without a restart. HTTPS Compression is a last resort, only with a secure VPN: compressed HTTPS pages can be exposed to the BREACH attack. With a reverse proxy handling HTTPS, HTTP Compression applies. See the Parameters article.
• Page History compares versions of a page: tick two versions and select Compare selected, or Compare with saved page to see what a save would change, and a Changes in this save column shows what each save changed. See the Save Page article.
• On Delay and Off Delay on alarms: the condition must stay true for the On Delay before the alarm is raised, and false for the Off Delay before it returns to normal. 0, the default, keeps the current behaviour. See the Alarms article.
• Docker on 64-bit ARM: the image is published for linux/amd64 and linux/arm64 under one tag, and docker pull selects the image of the host.
  • Python packages with compiled code need aarch64 builds on ARM: pip wheels, offline wheel sets and compiled .so files in Python Libraries. Version tags before 2026.11.02 remain linux/amd64. See the Docker article.
• Certificates on Docker: OPC UA, MQTT and Kafka use certificates from the /app/certs folder of the container, so secure connections work on Docker as on Windows.
  • The OPC UA client keeps its certificate in /app/certs/pki when the container is recreated, and MQTT and Kafka read TLS certificates from /app/certs/tls; mount /app/certs on a volume. Kafka devices get their own TLS certificate settings. See the Docker and Kafka Devices articles.
• Popups are drawn as soon as they open instead of showing a white box, and on a page with Fit Mode Fluid a popup always opens inside the browser window, also on a phone. See the Actions article.
• The runtime toolbar keeps its position and its minimized state per browser, also when another page opens.
• Text objects: Padding can be set over the Design API and MCP, and Padding and Font Size take a bare number as px. A new Button starts with 0px 12px padding.
• Config API: a request with many items is processed considerably faster.
• Configuration pages: Reset columns restores the default column order at once.
• Minor bug fixes and GUI improvements.

2026/10/20

• Security release. See the Security Advisories page for details.
  • The .NET runtime and System.Security.Cryptography.Pkcs are updated to 10.0.13, which fixes denial-of-service vulnerabilities in these Microsoft components (ESA-2026-009).
• Before you upgrade. The setup installs the ASP.NET Core Hosting Bundle 10.0.13 and asks to restart the computer. Plan an upgrade window, on both nodes of a redundant pair.
• History Source on every variable: trends read the history from the EnvisionSCADA Historian, from a query on a Database Connection or from a Python Module script.
  • Set on the Historian tab of every variable type and on UDT variable members. The Trend Analyst, Quick Trend, the Trend object and GetHistoricData read each variable from its source. Live values still come from the variable, so Historian can stay off and the data is not stored twice.
  • Database runs a SELECT on a SQL Server, MySQL, SQLite or PostgreSQL connection. An empty History Query reads back the table a Data Forwarder writes.
  • Script calls fetch() of a Module script, for example to trend the archive of an external historian. Pens of the same script and History Parameters are read in one call. Test and Browse on the Historian tab check the source before saving.
  • When a history cannot be read, the Trend Analyst shows the reason above the chart instead of an empty line. Renaming a Database Connection or a Module script updates the variables that use it. See the History Sources article.
• Format on every variable, a display format such as 0.00 or #,##0.00.
  • Shown by the Trend Analyst (pens, tooltip and summary), Label, Input, Knob, Slider, the Trend tooltip, Data Grid Variable columns, the right-click menu, Quick Trend, alarm and event messages and the Recipe Manager. An object's own Floating Point and Decimals still take precedence.
  • The Format only changes how a value is shown: alarms, expressions and every write keep the full value, and so does the historian unless Round to Format is on.
  • Round to Format on the Historian tab stores the historian samples rounded to the Format, and the deadband compares the rounded values. Off by default.
  • Bar Graph, Radar and Donut get a Format setting for their values, and ReadVariable in the runtime API returns the Format.
• The Alarm Viewer object gets an Asset setting, an asset path or a variable holding one, so one page can show the alarms of any asset. The severity counts follow the search text and the column filters.
• Screen Notes: Add Note is offered on every spot of the page, also on shapes, pipes, images and group backgrounds.
• The Donut moves its slices to new values instead of redrawing from zero on every change.
• Replacers written in square brackets, such as [PLC], are now also replaced by Navigate To, Pull, Push and the API and MCP instance create and push. A token that stayed raw is replaced at the next navigation, push or pull.
• Configuration pages: a checkbox edit that the server refuses unticks again.
• Minor bug fixes and GUI improvements.

2026/10/17

• Before you upgrade. This release converts the historian to a compact format and changes Database Query and Kafka.
  • The historian is converted on the first start, behind the migration progress page, and takes about half the disk space afterwards. Take a backup first: an earlier version cannot open a converted historian. The conversion needs little extra disk space and resumes where it stopped after an interruption.
  • HistoricData is now a view, so trends, reports and your own SQL keep reading it. A script that looks the table up in sqlite_master with type = 'table' has to accept a view: see the Database Migration After an Upgrade article.
  • Database Query now runs against a Database Connection. Page scripts call PageDatabaseQuery(connection, sql), and a connection is opened to queries with Allow Database Query and an optional Access Right. The DatabaseQueryAllowAll, AllowedSqliteDatabases and AllowedSqlServers parameters are removed, so scripts using the old call have to be converted: see the Database Query and Database Connections articles.
  • Kafka: KafkaProducer and KafkaConsumer are removed. A variable linked to a Kafka device is produced; consuming needs the new Consumer switch on the device and Writeable on the variable. Existing configurations are converted, and the produced messages are unchanged.
  • SQL Server connections use Microsoft.Data.SqlClient. A connection string without an Encrypt key behaves as before; Encrypt=True now also validates the server certificate.
• New MQTT Publishers page, which publishes variables to external MQTT brokers and accepts writes from them.
  • EnvisionSCADA systems can now exchange data with each other through a broker, for example edge systems with a central system. This is the first step towards the upcoming fleet manager feature.
  • Each variable and UDT member has an MQTT Publisher field on the Gateway tab. Topic and payload templates, Status Topic with Last Will, QoS, Retain and a minimum interval are set per publisher.
  • Writes from the broker need Subscribe on the publisher and Writeable on the variable. Only the primary publishes, and it republishes the full state after a failover.
• Sparkplug B 3.0, as edge node and as host application.
  • Edge node: Payload Format Sparkplug B on an MQTT Publisher, with birth and death certificates, report by exception, Rebirth and NCMD/DCMD writes.
  • Host application: Protocol Sparkplug B on an MQTT device, one device per edge node, with Browse Sparkplug Metrics to add the metrics as variables.
  • Passes the 10 tests of the Eclipse Sparkplug TCK 3.0.0.
• Screen Notes and Quick Trend on runtime pages.
  • Both open from a right-click (press and hold on touch) and are switched on per page with Allow Screen Notes and Allow Quick Trend. They are off by default, so existing pages are unchanged.
  • Screen Notes are shared notes on a page, audited, and removed after their Remove After time. The new Screen Note Edit Right controls who may add and edit them.
  • Quick Trend collects up to 8 values from the page and opens them in the Trend Analyst, in a window over the page or as a full page.
• New Translations page, which edits the project language texts in a grid, with views for missing texts, Rescan Project and CSV export and import. The AI Assistant can fill in missing translations from this page.
• Database Connections: PostgreSQL and TimescaleDB for Data Grids and Data Forwarders, and InfluxDB 2.x and 3 for Data Forwarders.
• Rights Matrix on the User Groups page, which edits the rights of every user group in one view.
• Network Topology improvements.
  • The Force layout stays live: nodes can be dragged and pinned, and an optional float keeps a gentle drift.
  • New Network Node Types page for the label and symbol of each node type, and a group filter menu on the object.
  • Import and Export on the Network Nodes, Network Links and Network Node Types pages.
• Group symbol fixes.
  • Push and Update act on the selected symbol on large pages, where they could update the wrong master or report Symbols Updated without writing an instance.
  • Instances updated by Push and Update no longer share object ids. Pages already affected are repaired when they are opened.
  • Push and Pull work on symbols with docked or fluid children, and show an error when they fail on the server.
• Driver and redundancy fixes.
  • BACnet: offline devices are detected in about 7 seconds instead of 72, a disabled device is no longer written, and a value that does not fit the variable is refused instead of written as 0.
  • Modbus TCP, S7, MELSEC and EtherNet/IP log and refuse an invalid write value instead of writing 0.
  • Browse Add Selected (BACnet, S7 Plus, OPC UA) has a Start names with {Device}. option, ticked by default.
  • A new standby receives the historian, alarms, events and audit trail of the primary from the first row.
• Data Forwarders: stored procedure targets filled from the template and the SQL Server Event Insert template work, and acknowledgements from the Event Viewer and of historic alarms are forwarded.
• Data Grid on SQL Server: a new row can be edited without a reload.
• A Set Value or Select Command action with a {Variable} that has no value no longer writes the variable name.
• Python GetBoolValue reads BOOL variables whose value is True or False.
• The Trend Analyst toolbar wraps on narrow screens instead of folding away.
• Minor bug fixes and GUI improvements.

2026/10/06

• Security release. See the Security Advisories page for details.
  • Trend Analyst data, the variable list and recipe exports require a logged-in user, and changing the enabled languages requires an administrator (ESA-2026-007).
  • The Alarm Banner shows alarm texts and acknowledge comments as plain text (ESA-2026-008).
• Before you upgrade. This release moves EnvisionSCADA to .NET 10 and Python 3.12.
  • The setup installs the ASP.NET Core Hosting Bundle 10.0.12 and asks to restart the computer. Plan an upgrade window, on both nodes of a redundant pair.
  • Python 3.12.10 replaces Python 3.11. Libraries installed with pip have to be installed again: see Upgrading from Python 3.11 in the Install Python Libraries article.
  • Alarm and event conditions, the Run When of UDT scripts and schedule Exceptions are suspended while a variable they read has no usable value, so a device going offline no longer raises or clears an alarm.
  • The User Groups of a variable now restrict writing only, not reading.
  • Upgraded installations have no Alarm Shelve Right yet. Grant it on the User Groups page.
  • The CSV exports of the Alarm Viewer and the Event Viewer now start with a header row. The Alarm Viewer export adds a Suppression column and the Audit Trail export an Asset column.
• Alarm shelving and suppression by design, following ISA-18.2.
  • Shelve an alarm for a set time or until it returns to normal, from the Alarm Viewer or an Alarm Banner. The new Suppressed Alarms list shows what is shelved or suppressed.
  • Parent Alarms, Suppress When and Release Delay (s) suppress the consequences of a parent alarm. Alarm members of a UDT carry the same settings.
  • New Alarm Shelve Right, shelving rules on the Parameters page, and ShelveAlarms, UnshelveAlarms and GetSuppressedAlarms in the Runtime API and MCP.
• Edit Mode has a docked toolbar, rulers and guides, snapping and a status bar.
  • The properties panel stays open and follows the selection. Right-click opens a context menu.
  • Changes no longer leave Edit Mode for a moment, so the zoom, the selection and the open panels are kept. Delete, group, move and align are each an undo step.
  • Object Viewer (CTRL+O) and the Z-Index Layers Viewer (CTRL+J) are redesigned. Ctrl+D duplicates, Ctrl+M resets the view and Esc deselects.
• Reports: Audit list and an Asset filter.
  • The new Audit list component and the Audit trail table source print the audit trail of the period, filtered by category, user and asset.
  • Alarm, event, audit and historian lists take an Asset filter, so one report can be run per asset.
  • Every new Audit Trail record stores the asset it concerns, and the Audit Trail page has an Asset column and filter.
• New variable status Unknown for a point that has not delivered a value yet, instead of 0 with the status Good. See the Variable Status article.
• The DNP3 driver has been rewritten. It no longer depends on external libraries, runs under Docker as well, and no longer stops the server when a DNP3 device is added.
• Reports, S7, S7 Plus and IEC104 are no longer BETA. S7 Plus checks the certificate of the CPU before it sends the password, with the new Certificate Validation setting.
• Driver and redundancy fixes.
  • Modbus TCP: UINT, LINT, ULINT and overlapping variables are read correctly, a BOOL on a register bit writes only that register, and Verbose 2 logs requests and responses in hexadecimal.
  • OPC UA: several variables on one array node all update.
  • Data Forwarders no longer forward rows twice after a reload, a failover or a switchover.
  • Replication to the standby no longer stops after Enable all or Disable all, and a rolled-back import no longer reaches the standby.
  • The primary accepts the buffered data, alarms, events and audit records of the standby again. Since 2026/08/08 the standby buffer did not drain, and a full buffer paused the backfill. After the upgrade the backlog is sent in the first cycles.
• Recipes: a variable can belong to several recipe targets, listed comma-separated in Recipe Targets.
• Pages can be duplicated from the Pages tree.
• Document Viewer shows CSV files, and Office files on a client with an Office viewer extension.
• Old log files are deleted, set by the new Log Retention Days (30) and Log Maximum Size (MB) (1024) parameters. On an IIS installation the setup now creates the Logs folder, so the error log is written.
• Find Master frames the master on the opened page with a pulsing blue ring.
• Update and Push of a group symbol no longer hang the server when the value of a replacer contains its own token.
• Access Control is now checked by the check box, knob, list box, drop down, date time picker, range slider and toggle switch objects.
• Minor bug fixes and GUI improvements.

2026/09/14

• Before you upgrade. This release migrates the Data Table object to the new Data Grid object, and moves database connection strings onto the new Database Connections page.
  • Every Data Table becomes a Data Grid when a project is upgraded or imported. A query on one table becomes the Table, Columns, Fixed Filter, Default Sort and Row Limit of the grid, and a query that a Page Script assigned to a client variable in OnPageLoad is resolved from that script. Column types are set to Auto and detected from the table.
  • Editing stays off on every converted grid until an engineer switches it on.
  • A query the migration cannot express, or one that a Page Script narrows at runtime, is kept on the object and reported as Attention in the System Log and in Database/DataGridMigration.json. Open the object in the designer, pick the Table or add a Fixed Filter, and the note disappears at the next save.
  • The connection strings of Data Table objects and Data Forwarders become connections on the Database Connections page, named after the server and database or the SQLite file, and the converted grids and the forwarders are linked to them. A connection that a Data Forwarder selects cannot be deleted.
  • A Database Connection is part of the project export and of the Git configuration files, connection string included, so a password written in a connection string travels with them.
  • Page Scripts are rewritten: PageGetSelectedDataTable becomes PageGetSelectedDataGridCells, PageDeselectDataTable becomes PageDeselectDataGrid and PageRefreshDataTable becomes PageRefreshDataGrid. The old names are no longer available, so a script typed by hand has to use the new ones.
  • PageFillDataTableDynamic has no replacement. The connection and the table now belong to the object; narrow the rows at runtime with a Fixed Filter that uses a variable, or with PageSetDataGridFilter.
• New Git Version Control dialog, which keeps the project configuration in a Git repository.
  • Open it from the Quick Menu (CTRL+Q). Every commit holds the complete configuration as JSON files, so a change is visible per file and the history of a project is readable outside EnvisionSCADA.
  • Commit & Push exports the configuration into the local copy of the repository, commits it as the logged-in user and pushes it. A push is refused when the remote holds commits this server does not have yet, so nothing is overwritten: run Pull & Import to DB first.
  • Pull & Import to DB fetches the current branch and imports the committed configuration into the database, with Import Options deciding how it is applied. Restore does the same for an earlier commit from the Recent Commits list, either replacing the configuration or merging the differences.
  • Branches are listed with the remote branches that have no local copy yet. Switch checks one out, and Create & Switch starts a branch from the current commit that reaches the remote with the next Commit & Push.
  • Repository Status shows the branch, the folder of the local copy and whether the exported files differ from the last commit; Output reports the result of the last action, including why one was refused.
  • Several servers can share one repository, an engineering server and a production server for example, each with its own local copy and its own token. The Personal Access Token is stored encrypted and never shown again.
• New Container object, a fixed-size scrollable container that can be split into tabs.
  • Each tab owns its own area of the container. When the content of a tab is larger than the container, the tab scrolls instead of growing. By default it has a single tab and no tab strip, a plain fixed-size scrollable container; the strip appears once a second tab is added.
  • Drop an object on the group, paste onto it with Ctrl+V, or move it to another tab with the On Tab setting. Objects on a tab behave like objects on the page: they can be grouped, resized, animated and used in group symbols.
  • Per tab, Tab Layout is Canvas for free positioning, or Left to Right or Top to Bottom for a flex layout where dragging reorders the objects and each object's Width is a pixel value, a percentage of the tab width, or Grow. Distribute and Align control how the objects are spread along and across the layout direction, and the Position / Size section shows a Responsive tag for such objects.
  • Content shows a tab at its design size with scrollbars, or scales it into the container with Scale to Fit or Scale to Width.
  • The tab strip height, font size, colors and alignment are configurable, and an optional Active Tab Variable selects the shown tab by name or index.
  • In runtime the chosen tab applies to that browser only. Wrapped in a Group, a Container can be part of a group symbol, with the tab names replaceable per instance.
• Pages can now adapt to the screen they are shown on.
  • New Fit Mode page setting: Off keeps the fixed page with zoom and pan, Scale to Fit scales the whole page uniformly into the window, Fit Width scales to the window width and scrolls vertically, and Fluid sizes the page to the window.
  • A Container can be positioned in Flow, placing it after the previous flow container and wrapping at the parent's width, and its Width and Height accept a percentage. With Fit Mode Fluid, a set of flow containers rearranges to the screen it is shown on.
  • With Fit Mode Fluid, the Max Width page setting stops the containers from growing beyond that width on wide screens and centers them.
  • The designer always shows the page at its set size; the Preview Width setting in the page context lays a Fluid page out at a phone, tablet, laptop or desktop width while editing, without saving anything.
  • The Design API and MCP tools expose the same settings (fitMode, fluidMaxWidth, data-layout, data-content, tab layout and flex attributes), an order attribute to arrange containers and objects, and a GetResponsiveLayoutGuidelines tool with the step-by-step recipe.
• New Data Grid object, which replaces the Data Table object.
  • It shows the rows of one table or view of an external database. The database is a Database Connection and the table is picked from that connection, so no SQL is written anywhere. Sorting, column filters, search and paging run on the database server, which keeps a grid on a large table responsive.
  • With editing switched on, operators add, change and delete rows in the grid or in a dialog. The insert, update and delete statements are generated on the server from the Table, the Key Column and the columns marked Editable, and the built-in EnvisionSCADA databases stay read only.
  • A write needs the primary server and the Access Right group, and in compliance mode with Electronic Signature on it asks for a signature. Every write is recorded in the Audit Trail with the key value and the changed columns.
  • Columns are filled in with Detect From Table or added by hand, and each column has a type, its own formatting and optional per-row buttons.
• New Database Connections configuration page, holding the named connections to external databases.
  • Data Grid objects read from and write to a connection, and Data Forwarders write to one. Both refer to it by Name, so a connection string is entered once and changed in one place.
  • SQL Server, MySQL and SQLite are supported. A SQLite connection points at a file, and a relative path resolves against the installation folder.
  • Test Connection opens the database with the values as typed, before or after saving, and reports the result and the response time. A template fills in the shape of the connection string for the chosen type.
• New Network Topology object, which draws the plant network as nodes and links coloured from live device status.
  • Every device is a node automatically. The Network Nodes configuration page adds the parts of the network that are not devices, such as switches, routers and servers, and Network Links names the two nodes each connection runs between.
  • The object lays the picture out itself, or follows the manual positions set on the nodes.
  • A node takes its colour from the status of the device behind it, so a connection that is down is visible on the page.
• New Radar object, which plots several values around a circular web.
  • Each axis is a spoke and each series is one closed polygon over all the axes, which suits a profile that is read by its shape rather than by exact values.
  • It takes the same data structure as the Bar Graph object: the categories become the axes and the series become the polygons.
  • Axis Minimum and Axis Maximum apply to every axis, and a Min or Max on a single axis takes precedence, so spokes in different units can each keep their own range. Left empty, the axes scale automatically.
• Exporting UDT definitions can now take their symbols with them.
  • The Include symbols option beside Export adds the masters bound to the types, the symbols nested inside those masters, the faceplate masters their popup actions open, and the Color Library entries their markup uses.
  • The import writes the masters first and only the ones the imported types need, each on the page it came from. A master that already exists is skipped unless replacing it is confirmed, and a colour is added only when its name is free.
• A page file now records the version it came from.
  • Its content is brought up to the current shape when it is imported, and a file from a newer version is refused rather than half read.
• Minor bug fixes and GUI improvements.

2026/09/01

• Added the S7 Plus driver for Siemens S7-1200 and S7-1500 controllers [BETA].
  • Uses the S7CommPlus protocol that TIA Portal itself uses, encrypted with TLS, and requires no PUT/GET communication to be enabled on the CPU.
  • Variables address PLC tags by symbol name with Browse Symbols, resolved from the symbol dictionary the CPU carries, and data blocks keep their Optimized block access setting.
  • The existing S7 driver remains the option for S7-300, S7-400, S7-200, S7-200 Smart and LOGO! controllers.
• The built-in OPC UA Server now supports security, authentication and Historical Access (OPC UA HA).
  • Enable Secure Channel offers Sign & Encrypt endpoints only (Basic256Sha256, Aes128_Sha256_RsaOaep and Aes256_Sha256_RsaPss). The server certificate is looked up by Subject Name in the Windows certificate store, or EnvisionSCADA generates one for itself, and Validate Client Certificate restricts which clients may connect.
  • With a Username and Password set, anonymous access is off and every client session must authenticate. On an unsecured endpoint the password is encrypted with the server certificate, so it does not travel in clear text.
  • Variables with Historize ticked expose their Historian data through OPC UA Historical Access: a client reads raw values for a time range with HistoryRead, paged at 10000 values per call. History can be read, never inserted, replaced or deleted.
  • In a redundant pair both servers run and publish the same data, and a write on the standby is forwarded to the primary before it reaches the device.
  • A new Verbose setting logs the effective security configuration, session authentication and history reads.
• A new installation now starts with a demo project.
  • It is loaded only on a machine that has no configuration database yet. Sign in with the user name Admin and the password Admin.
  • New Project replaces it with an empty project. The package stays in the Demo folder of the installation folder, so Import Project can load it back.
• The installer now restricts the Database folder to SYSTEM, Administrators and the IIS worker accounts, a 21 CFR Part 11 hardening step that previously had to be applied by hand.
• The AI Assistant now works with the latest Claude models.
  • Claude Opus 5, Sonnet 5, Opus 4.8, Opus 4.7 and Fable 5 no longer accept a sampling temperature and refuse a request that carries one, so every message sent to one of those models failed with a provider error.
  • The parameter is now left out for those models, and a request that is refused because of it is retried once without it. On those models the AI Temperature parameter is ignored and the provider default applies. Earlier Claude models and the OpenAI models keep using AI Temperature.
• Minor bug fixes and GUI improvements.

2026/08/08

• Security release. See the Security Advisories page for details.
  • An installed build now always runs as Production, so a Development environment setting on the server can no longer expose error detail (ESA-2026-006).
• Before you upgrade. This release migrates the historian and tightens a few naming and API rules.
  • On the first start after upgrading, the historian is rebuilt behind a Database migration in progress page. The engine stays down and the API returns 503 until it completes. Allow roughly 35 seconds per 1.5 GB of historian, and up to an hour for the index rebuild on a very large historian. The migration needs 10% of the historian file size in free disk space (at least 256 MB) and is refused up front if that is not available. It can be interrupted and resumes where it stopped.
  • Variable, device, UDT instance, asset and recipe parameter names may no longer contain a hyphen or a #. Existing projects keep running, but a name containing either character is refused the next time that row is saved. Rename them at your convenience.
  • Runtime API: the separate Device field has been removed from the read and write variable requests. Pass the full variable name in Variable.
  • Design API: GET /API/Design/Objects now returns a summary list, and the per-object read is replaced by GET /API/Design/Objects/Details with an objectIds list.
  • Design API: attribute values are validated when written. A value that used to be accepted and then failed at runtime, such as a data-actions object where an array is expected, is now refused at save with a message naming the fix. Existing pages are not affected.
  • The recipe field is called RecipeTargets everywhere in the API, MCP and exports. Existing recipes keep working and older project exports still import.
  • Python scripts: while True: and while 1: are refused when the script is saved. Use Schedules for repeated execution. SetValue with a boolean now stores 0 or 1.
• Variable names are now free form.
  • A name is stored and used exactly as written. The {Device} replacer is optional and resolves to the owning device.
  • Use {Device} when several devices share an identical variable set that would otherwise collide. A literal name stays as it is when the device is renamed, while a name using {Device} follows the rename.
  • Local variable names are unrestricted, and a name without a dot such as Counter is valid.
  • A resolved name must be unique across the whole project.
  • Variables can now be arrays.
• New Asset Manager and User Defined Types, to define a piece of equipment once and roll it out across the project.
  • Asset Manager is the entry point for both the asset tree and the type library. Build a hierarchical asset tree and drag nodes to re-parent them.
  • Define a type under UDT Definitions, on the Parameters, Variables, Alarms, Events, Scripts, Slots and Symbol tabs.
  • A type can inherit from a Base type and contain other types through Slots. Members can be conditional with Include when, and can be arrays using Array size and First index.
  • Create instances one at a time, or many at once with Create multiple using Count, Start at and Zero-pad. One instance can span several devices.
  • Nothing in the project changes until you push. Push preview lists exactly what will be created or changed per instance, asks for a Reason, and can Adopt existing rows with matching names.
  • Per field, Override releases a single field on a single instance so it can differ from the definition without detaching the instance.
  • Bind a group symbol to a type, then place it with Place on page or by dragging the instance onto the page.
  • Export and import whole types, individual tabs as JSON or CSV, and single instances.
  • Cross Reference searches UDT templates as well, and marks rows that are managed by a definition.
  • The whole lifecycle is available over the configuration API and MCP.
• New Report Designer for graphical reports, on the new Reports configuration page [BETA].
  • Build a report from Header, Text, KPI row, Trend chart, Table, Image, Alarm list, Event list, Columns, Spacer and Page footer components.
  • A Table reads from Project SQLite, Historian, Alarms or Events.
  • Banded or Free canvas layout, A4 or Letter, portrait or landscape, with Design, Preview, Output and Script views and undo/redo in the designer.
  • The reporting period is a preset (yesterday, today, last 24 hours, last 7 days, last 30 days, this month, last month) or comes from variables.
  • Reports render to PDF, and additionally to .xlsx when Excel compatible is enabled for a banded report.
  • Run a report from the Execute Report page action, a schedule, an alarm or event action, Python RunReport(), MCP, or Execute now on the Reports page.
  • Per report, User Groups controls who may run it from a page. Left empty, only Administrators can.
  • Python SendEmail() can mail a report that a script just produced.
  • Rendered files are kept until you remove them. There is no automatic retention yet.
• New Document Viewer object, and five product pages that can now be embedded on a page.
  • Document Viewer shows a rendered report or a project document inline, as PDF, PNG, JPG, GIF or TXT. Access is granted per user group under Document viewer access in Parameters.
  • Alarm Viewer, Event Viewer, Audit Trail Viewer, Trend Analyst and Users can be placed directly on a page as objects.
  • A DropDown or ListBox can list a folder, so an operator picks a rendered report instead of typing a path.
• Added 21 CFR Part 11 support for regulated installations.
  • New Part 11 Compliance (21 CFR) section in Parameters with Enable Part 11 Compliance Mode, off by default. It disables Guest login, disables deletion of historic alarms and events, enforces electronic signatures and applies a mandatory password expiry.
  • New Audit Trail Viewer page. Records are append-only and hash chained, and cover configuration and runtime changes made from the interface, the API, MCP and Git. Verify Chain reports whether the chain is intact.
  • Electronic signatures ask for user name, password, Meaning and Comment, and are recorded against the audited action.
  • Signature Required Actions selects which actions need a signature, from Config.Save, User.Edit, Recipe.Download, Variable.Write, Alarm.Ack and Project.Import. Disabling compliance mode always requires one.
  • New Audit Trail View Right per user group.
  • The audit trail records regardless of whether compliance mode is enabled.
• EnvisionSCADA can now act as an MQTT broker.
  • New MQTT Broker section in Parameters with the port, Enable TLS (MQTTS) and TLS port, a certificate, Allow anonymous connections and Enforce topic access control.
  • MQTT broker users are managed in their own dialog with credentials and Topic access control rules per user, each rule combining a Topic filter with the allowed access. A topic that matches no rule is refused. Rules can be imported and exported.
  • New MQTT broker log page showing live broker activity, with Pause, Clear, Export and Connected Clients.
• Added two device drivers.
  • EtherNet/IP Generic [BETA], using CIP explicit messaging addressed by class, instance and attribute. It is a separate driver next to the existing Ethernet/IP tag-based driver, which is unchanged.
  • Beckhoff ADS [BETA] for TwinCAT 2 and 3, addressed by PLC symbol path or by index group and offset.
  • The Ethernet/IP tag-based driver received write, PLC type validation and connection status fixes.
• New Map object to show equipment on a geographic map.
  • Map Style offers Street, Terrain, Light, Dark, Humanitarian and Satellite, with an optional Lock View (runtime).
  • Edit Map Children places group symbols on the map, positioned by a single variable holding latitude and longitude, or by separate Latitude and Longitude values.
  • Min Scale and Max Scale let symbols grow and shrink with the zoom level instead of stacking.
  • Dragging a group symbol instance onto a map adopts it, after which its asset or coordinates position it.
• New SVG Editor for preparing symbols.
  • Open it by right-clicking an image in the library, or with Open in SVG Editor on the object.
  • Paint slots list every fill and stroke in the drawing, and each one is set to Runtime, so it follows the object color states, or Static, so it keeps its own color. An outline can stay black while the body animates.
  • Readiness and Prep for library check a symbol before it goes into a library, and the preview shows it against a checker background and against light and dark themes.
  • All 321 symbols in the 1 P&ID library were cleaned up so they scale correctly when placed. Their colors are unchanged.
• The Color Library now holds multiple themes.
  • Add, Rename, Delete a theme and mark one as Default. Every theme carries the same color names, so only the values differ.
  • The Select Theme object action switches theme per client. The choice survives a reload and is available as client.SelectedTheme.
  • The page background, the Login, Viewer, Numpad and Keyboard colors, the alarm state colors and the Trend Analyst pens now accept a color name from the library, so they follow a theme change.
• Renaming something now offers to rewire the places that still name it.
  • Applies to a variable, device, Python script, converter, page, report and user group, from every screen that can rename, including the Asset Manager and a UDT push that renames materialized rows.
  • Saving a rename answers with what still uses the old name: page objects, alarm and event conditions and messages, Python scripts, schedules, converter expressions, report templates, UDT definition members and UDT instance parameters.
  • Every place found carries a tick box, ticked by default, with a search over Type, Location and Context and the matched name marked in the Context column, so a name used as prose in an alarm message or a comment can be left alone. The button reports how many places will be updated, and the result and the audit record state what was deliberately left unchanged.
  • Keeping the old references is a valid answer, for example when a variable is renamed so the existing references point at a different one. The references can also be reviewed in Cross Reference first.
  • Matching is on the whole reference, so renaming Flow1 leaves Flow10 alone. A user group rename also updates the User Groups lists on variables, pages, scripts, reports and UDT members, the user memberships, and page objects that test SYSTEM.UserGroups.
  • Historian samples keep the name that was in force when they were recorded and are never rewritten.
  • The preview and the apply are available over the configuration API and MCP, the preview writing nothing.
• An alarm or event whose condition cannot be evaluated is now reported instead of staying silent.
  • The System Log Viewer names the alarm, the problem and the condition, so the missing variable can be found and fixed, and reports a recovery line once the condition works again.
  • A mass failure, such as one bad push or a device whose variables were removed, is reported in batches with an outstanding count rather than being swallowed.
• The configuration and designer screens are now fully translated.
  • The remaining English text was added to the Edit Mode translations, including the certificate and CA generators, License, System Log Viewer, the Envision toolbar and the object context menus, the Python editor, the Report Designer, the AI chat sidebar, the MCP OAuth, AI chat and OPC UA blocks in Parameters, and the device help text.
  • The data grid header, filters and paging on the runtime viewers follow the operator language.
  • Accented and non-Latin characters no longer appear as character codes in dialogs, confirmations and tooltips.
• Added a Simulation mode per device.
  • Available on Modbus TCP, OPC UA, Ethernet/IP, EtherNet/IP Generic, S7, DNP3, BACnet, IEC104 and MELSEC devices.
  • A simulated device makes no connection. Its variables read and write in memory like Local variables and report Good, and the device reports Simulation as its state. Values are not retained across a restart.
• IEC 104 commands now have a per point Command Mode.
  • Direct execute, Select before operate, and Select before operate (operator).
  • The operator mode gives the page three actions, Select Command, Execute Command and Cancel Selection, so a selection can be reviewed before it is executed and released if it is not. A device level Command Select Timeout bounds it.
  • Commands are reported only once the device confirms them.
• Added a Restart Device action, available on a button, an alarm, an event, a schedule, from Python and over the API, so a single device can be restarted without restarting the server.
• Added dual-LAN path redundancy for the primary and standby link.
  • Each participant can carry a second IP address on a separate network. The heartbeat probes both paths and synchronization follows the one that is up, so a single failed cable or switch no longer interrupts it or forces a role change.
  • The Certificate Generator accepts the second IP address so one certificate covers both paths.
• OPC UA Browse is now an expandable tree of the server address space, with Expand All, Search, Update Node IDs and Add Selected.
• Polylines can show arrowheads and crossing bridges, and objects can rotate continuously.
  • Arrow Start and Arrow End offer None, Arrow and Open Arrow, with an Arrow Size.
  • Bridge Crossings draws a small hop where a polyline crosses another one it is drawn over.
  • Rotate Continuously, with Rotation Speed and Rotation Direction, is available on SVG, Image, Label, Square, Circle and Polygon objects.
• Performance improvements.
  • Trend objects redraw only when their data changes, which is noticeable on pages carrying many trends.
  • Python scripts no longer hold the interpreter while waiting for device reads and writes, so scripts no longer block each other during device access.
  • The historian is no longer integrity checked at startup, which could take hours on a large database and prevented the server from coming up.
  • Historian indexes that could not be used were removed and the remaining ones slimmed.
• Configuration API, Design API and MCP improvements.
  • Create or update a batch of design objects in a single page save, with consistent arguments and partial updates.
  • Online and Offline project files can be listed, uploaded and downloaded over the configuration API and MCP.
  • Alarm actions are available over the runtime API and MCP, gated by user rights.
  • Signature-gated actions can be driven over MCP by passing a signature token.
  • Optional OAuth 2.0 for MCP, off by default, configured in Parameters.
  • Design API: attribute values are validated against the published rules when they are written, so a malformed value is refused at save instead of failing when an operator clicks the object.
  • Design API: polyline and polygon geometry can be read back, and a polyline created over the API draws the line style and cap it was given.
  • Design API: the object metadata states the minimum frame width for the viewer objects and the Document Viewer.
• Python improvements.
  • SendEmail() sends mail with attachments, and RunReport() renders a report.
  • Output from a manual execution is captured per run, and files a script produced are listed for preview.
• Interface improvements.
  • Text alignment is now available on the input, button, picker, dropdown and list box objects, not only on the label.
  • A label can drive conditional colors on its background as well as its text.
  • Alarm banners, data tables, dropdowns and list boxes take their configured colors at runtime.
  • The variable picker is offered wherever a variable name is typed.
  • Copying a group symbol gives the copy its own name instead of appending to the previous one.
  • A new push dialog shows the replacer matrix when pushing a group symbol to its instances.
  • Polyline and polygon points follow the cursor at any zoom level and land on the page grid.
  • A popup opened with a Popup Context closes the popups already open in that context, also when the context comes from a group symbol replacer.
  • An empty value can be written to a variable from the Set Value dialog, and a value that is not a number reports why instead of closing without writing.
  • A Read Only label with no actions of its own passes clicks through to the object behind it, so a label over a button no longer blocks that button.
  • Importing alarms or events keeps a standing alarm standing, instead of displacing it and raising it again as a new occurrence with a fresh time and an extra alarm count.
  • The trend property window follows the page theme instead of always being a white panel.
  • An unexpected error now shows a branded page with a reference number for support instead of a developer message.
• Minor bug fixes and GUI improvements.
