Bug Fixes and Stability Improvements
Several issues have been resolved for a more reliable experience

CODESYS SoftMotion Staubli allows to control Staubli robots of the TS2 and TX2 series with CODESYS using the uniVAL drive interface.

CODESYS EtherCAT version 4.10.0.0 contains a known issue with the function "Load PDO info from the device", which prevents it from working properly with the CODESYS SoftMotion Staubli Support package. Please use either an earlier or a newer version of CODESYS EtherCAT instead.

This version introduces the new, application-based subscription licenses that can be updated via the Store. It also includes maintenance of Persistance Manager (15), DataLog Manager (5) and others (11).

Maintenance release with bug fixes.

This version contains several bug fixes including

Refactoring:

• Dialog shows wrong places of changes in page-oriented CFC
• Renaming an FB instance leads to rename of box type

Project Update:

• When updating a project from SP16P9 (CFC 4.2.0.0) to newer versions like SP19P4 or SP20P2 (CFC 4.3.0.0 / 4.4.0.0), the alignment of boxes (inputs/outputs) and connecting links changes unexpectedly due to the introduction of the "Hide namespaces" feature

CODESYS SoftMotion 4.19.0.0 brings support for additional axes to our robotics functionality.

This version fixes a bug, that in case of a communication error generated many log entries.
Moreover it fixes a bug of the PN Controller that may occur in special situations when disabling and re-enabling devices.

This version contains bug fixes.

This version fixes sporadic crashes when disconnecting a data source from an OPC UA Server. Also some issues when working with datas sources at engineering time are fixed.

This version will support the CODESYS Redundancy add-on.
Moreover it includes the support for network redundancy by the client, given that the servers support more than one connection.
It also contains bug fixes and minor improvements.

The release of our SIL2 certified runtime based on runtime system SDK V3.5 SP21. This version includes the PLCOpen Safety V2.0 function blocks for factory automation.

This version optimizes the treatment of 7bit-ASCII-only strings and simplifies the exchange with classic string functions by an internal terminal null.

Contains a fix for issues with the TEST_AND_SET operator not working reliably.

Issues with jumps in very large POUs on ARM Cortex targets are fixed.

This version contains improvements in diagnosis and in the decoding and writing of structures & arrays.

This release includes usability improvements.

Analysis results can be exported in the SARIF format which allows to view and process it in third party tools and CI workflows.

This version contains compatibility improvements and bug fixes, supporting additional PLC types.

Bug fix version for a more robust online communication with CODESYS Safety Extension.

Adjustment of the execution order within a network. 
In this version, the execution order within a network is the same as in LD FBD.

Preview version of the Simulation Interface for evaluation and integration in simulation tools (please contact sales): The Simulation Interface integrates CODESYS applications into machine simulations (Software-in-the-loop) by a toggle switch using OPC UA mechanisms.

The code generation for a recipe definition has been further optimized for array of struct.
A few important bug fixes have been made.

This version allows communicating with Azure IoT Hub via WebSocket proxies, provides a new library for accessing a Weather Forecast service, and includes maintenance of MQTT Client, AWS IoT Core Client, SNMP Service, Mail

A few important bug fixes and smaller improvements have been made.

This version contains bug fixes.

Update with improvements and bug fixes!

This version can be used without references of to-be-discontinued CAA libaries, and contains optimizations of "Element Collections".

Service packs for CODESYS V3 are released at annual intervals and include numerous improvements and bug fixes.

Maintenance release containing bug fixes and usability improvements.

This version changes the encoding of array data types conforming to the specification and compatible with other OPC UA tools.

This version contains bug fixes and minor improvements.

Besides bug fixes and improvents, this version will bring a network overview page with all connections of all adapters.

Last maintenance release before start of the service phase.

Created the possibility for device manufacturers which use their own licensing mechanisms for the engineering environment to integrate the CODESYS Professional Developer Edition into their systems.

Maintenance release

This version contains bug fixes and improvements.

This version contains bug fixes and minor improvements.

The POU Visu Generator can generate visualizations from SFC and Ladder POUs. If a transition of a SFC POU is implemented as Ladder, a navigation into the Ladder transition and back to the SFC POU is generated. A great possibility to view SFC and Ladder diagrams within the visualization.

This version contains several bug fixes and minor improvements.

Support of Application Based Bundle-Licenses

The usage of the memory tools is supported for core dumps.

This version adds language support for Turkish and Portuguese and contains a bugfix.

• This is the initial release for supporting the DNP3 protocol in CODESYS applications. The protocol can be configured and used through a new library for DNP3. A CODESYS Store Runtime product for Linux with at least version 4.10 is required for using DNP3.
• Known Limitations:
• configurator is not available, DNP3 can be used through an user-friendly library
• In this first release, only the usage of a CODESYS device as an outstation is supported.

This version contains bug fixes and minor improvements.

This release fixes the problem that projects may get modified on opening, when they use libraries from Inspection-supporting library addons (currently CODESYS Base Libraries, CODESYS String Libraries).

This is a maintenance release fixing known issues for the usage of packed data structures. Furthermore, the usage of the FPU can be disabled explicitly for devices.

Improved support for Clang / LLVM EABI

Improved support for Clang / LLVM EABI.

By serving as a gateway, this version enables proprietary add-ons to connect to IO-Link devices.

Fixed issues in certain cases when using pack_mode attribute on ARM based devices.

Support new functionality standardized in BACnet standard ASHRAE 135-2020 and protocol revision 25.

Update of "CODESYS Application Composer Single License" only, no functional changes. This update is necessary for running "CODESYS Application Composer" (any version) in SL-mode on any new CODESYS versions starting with V3.5 SP19 Patch 3. It cannot be used with older CODESYS versions. For using "CODESYS Application Composer" with older CODESYS versions, use the old "CODESYS Application Composer Single License".
