• 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.

Maintenance release

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

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

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

Support for additional data types and events is added to complete support of DNP3 Level 1 for the outstation library.

Additionally support for implementing a DNP3 master will be added.

With this version, the Automation Server has its own file system in the cloud to store any files. In addition to pure file storage, this also enables additional files to be remotely deployed to PLCs along with the actual CODESYS application.

New version enhances the SubNodeCom library to provide more detailed and precise diagnostic information.

This version contains performance improvements and bug fixes.

• added out-of-license message with configurable threshold
• added possibility to execute configurable batch file, once license threshold is reached
• added license restore support
• support of license name instead of only product codes

This version introduces message security for Pub/Sub for runtimes V3.5 SP21 or later (with runtimes < V3.5 SP22, it must use the same certificate using in other OPC UA functions). Additionally, the OPC UA Pub/Sub license is included in the "software metrics" dialog.

This version prepares the transition to version 5.0: It provides unbound-placeholder resolution for the Memory Block Manager library of CODESYS. This allows for add-ons and for projects that can safely switch between Base Libraries 4.0.1 and 5.x.

This version contains bug fixes.

Fixes issues with exception handling in IEC code. This is required to resolve issues with using OPC UA and BACnet on devices with LoongArch CPUs.

This version contains bug fixes and some small additions to existing scripting drivers.

This version contains several Bug-Fixes.

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 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

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