CODESYS^® Release Plan &
Roadmap

Maintenance Update

This version will contain bug fixes and improvements.

• Optional additional I/O channels that contain diagnosis information of each single Modbus channel.

• New FB ModbusTCPRequestServer that allows the application to control the server's answers to requests from the client.

This version will contain bug fixes, improvements and the following new features:

• Topology Editor that displays graphically all involved devices and its connections.

• Dynamic Reconfiguration to support online change when modifying/adding devices.

• Support of GSDML specification V2.46

• Show newest installed device only

  • Per default, no more duplicates / older versions of a device are shown.

• SysEthernetBurst

  • Use new runtime interface (included in SP22) that sends and receives multiple Ethernet frames with one call.
  • Noticeable performance improvement.

New library implementing the SRCI interface for commanding robots of various vendors.

The Simulation Interface integrates CODESYS applications into machine simulations (Software-in-the-loop) by a toggle switch using OPC UA mechanisms (machine simulation requires compliant connector).

This version can only be used with new versions of CODESYS Communication, Visualization, Ethernet IP, Application Composer, Control Loop.

It introduces the new File_and_Dir library for synchronous and asynchronous file and folder operations which improve on CAA File and SysFile/SysDir.

And it cuts dependencies on CAA libraries. This introduces an incompatibility where user-defined data types are used in Element Collections (they now need to implement MBM.IDisposable).

Also it includes fixes for multi casting (BASLIB-239) and online change (BASLIB-63).

The first stable release after the 0.9 preview brings key improvements, including: • An updated and cleaner file format • Harmonized line endings for improved Git compatibility • Optimized user experience (SP22 improvements) • Compatibility with CODESYS Git V2.0.0.0 • Optimized Scpripting driver Perfect for professional, file-based project management!

Maintenance and usability version. This version will support ConformanceTest 22.

This version contains several Improvements and Bug fixes. For example the usablility will be improved by enablling the horizontal scrolling with the mouse wheel.

With this version we will improve the usability for certificate signing request (CSR) and certificate revocation lists (CRL)

This version contains several improvements and bugfixes.

Besides several bug fixes, this version contains usability improvements for CODESYS Safe Control Core 4.2.0.0

Enables the usage of the Test Manager in noUI mode for CI/CD workflows.

New major version of the Git Integration which works directly on top of a CODESYS file based storage project. This means that human readable project representation is available by default enabling new use cases for our git Integration.

Support for the RISC-V 64-bit CPU Architecture.

This version introduces complete UI-less Python scripting. Also it fixes a problem with very long module descriptions (>32k) and adds forward compatibility with upcoming CAA-free BASLIB 5.0 (and also still with CAA-based BASLIB 4.0.1).

Maintenance release

Support of an external FB interface, which enables the user to extend the safe functionalty with additional functionblocks.

Support of 64bit ARM/x64

This version contains mainly bug fixes and some improvements in various product areas.

Maintenance version.

Maintenance version.

This version provides a new Web Client library using modern Strings (STRLIB) and supporting the content-type "multipart/form-data".

This version adds support for AxisGroup objects.

This version contains mainly bug fixes and some improvements in various product areas.

This version brings two new visualization elements:

• Donut Gauge / Round Slider to display and modify values

• Donut Chart for a quick overview of percentage values

In addition, many more improvements and bug fixes have been made.

This version brings support for MC_MovePath, which allows to use the G-Code processing from SoftMotion CNC to move an axis group from SoftMotion Robotics.

The new Ladder introduces a fully customizable toolbox. Improved workflow, plus multiple important bug fixes.

Allow UTF-8 identifiers for the trace name and traced variables in the Trace Editor.

First release of the new development system

• Compatible with CODESYS Control V3 – there will be no separate runtime for CODESYS go!
• Add-ons programmed as libraries are reused from CODESYS V3.
• Platform-independent engineering tool for CODESYS PLCs
• Backend running on desktop, server or on the PLC itself, if Windows- or Linux-based
• Frontend running on any device with web browser support
• Textual project storage

V1.0.0.0 will provide limited functionality compared to V3 focusing on two use cases:

• Implementation of simple applications that do not require more than the currently available functionality
• CI/CD for libraries

Available functionality

• UI and essential editors
  • Navigator
  • Editor / view host
  • Command infrastructure
  • ST editor
  • Enhanced offline functionality
  • Online mode and monitoring
• Compiled library generation
  • Compatible with V3
  • No library documentation support, yet
• Ladder editor
  • No professional coding features e.g. IntelliSense, auto-declare, underlining errors in the editor yet (planned for 2026)
• Devices & Fieldbus
  • Basic support
  • GPIOs for Raspberry PI
  • MODBUS TCP Server and Client

Fixes sporadic issues with the atomicity of the TEST_AND_SET operator.

Maintenance release Fixes sporadic issues with the atomicity of the TEST_AND_SET operator.

Enable usage of codegenerators for ARM architecture in CODESYS go!

This version includes bug fixes. The inlcuded third-party components will be updated to the latest available versions.

Enables an LLM to interact with the CODESYS Development System through the Model Context Protocol interface. To achieve this, an MCP server is integrated into the Development System. The server provides a set of so-called tools that allow an LLM to:

• Read project contents
• Create or modify datatypes and POUs using structured text
• Use the compiler and retrieve compiler errors
• Access library documentation

This version contains several bug fixes and improvements for the installation process. Users can now select required packages directly from their local hard drive, ensuring a smooth and complete installation even when the deployment server is missing components.

This version contains several bugfixes and improvements.

Maintenance version. It will support the IO Device Description Scheme 1.1.5.

Maintenance version.

The data source online change can be licensed and activated using the new store product "Online Configuration Change"

This version includes bug fixes.

• New file management features:

  • Deploy additional files along with applications
  • Transfer multiple files or folders to multiple PLCs at the same time
  • Move files and folders within the file management

• Remote access to Edge Gateway logs

• Automatic certificate renewal for encrypted connections

• Update to runtime SDK V3.5 SP22 Patch 1
• Support of EWF licensing containers
• XDP support of Ethercat and Profinet on x86 systems
• Execution of Linux-based SL runtimes with specific user rights, not generic root access
• Rework with various improvements of SL Deploy Tool
• Integration of performance and support report via plc shell command
