Post by mjam04 on AM243 LaunchPad as PROFINET Device with CODESYS – RPC Aborted error when scanning devices ^{CODESYS Forge talk (Post)}
Hello, I am currently trying to use the AM243 LaunchPad as a PROFINET device and connect to it using CODESYS. In my setup I am also using a Raspberry Pi running the CODESYS PROFINET Runtime, which acts as the PROFINET controller. The setup of the Profinet controller is correct, so all devices are in the same subnet. However, I encounter an issue when scanning for PROFINET devices in CODESYS. The AM243 LaunchPad appears in the scan results, but the following error is reported: RPC Aborted: 0x16C9A049 Additionally, CODESYS shows the message that the identification data is not available and the IP address should be checked. Because of this error, the controller cannot establish a connection to the device. Another observation is that I cannot ping the AM243 LaunchPad from my PC, even though I configured what should be the correct IP address. Setup: PROFINET Device: AM243 LaunchPad PROFINET Stack: Industrial Communication SDK example PROFINET Controller: Raspberry Pi running CODESYS with PROFINET Runtime Engineering PC: CODESYS IDE Network: Ethernet connection between PC, Raspberry Pi, and AM243 In the attachments there is a screenshot of the corresponding error. Did anybody had the same error? Any hints or debugging suggestions would be greatly appreciated. Thank you!

Hi, It was my fault. I was using a REAL variable instead of INTEGER. Sorry for posting this.

Hi tommyk-mar, do you call SMC_SmoothPath after SMC_NCIntepreter? Both G51 in the G-Code and the function block call are needed. You can see how this can be done in this example: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_cnc_3.html Best regarsd, Georg

Post by mrkm-dic on CODESYS: Combining Master Redundancy with EtherCAT Ring Topology – Is it Supported? ^{CODESYS Forge talk (Post)}
Hello, I would like to ask whether it is technically supported (and practically achievable) to combine CODESYS Master Redundancy with EtherCAT ring (loop) redundancy in the same system. System setup CODESYS version: CODESYS 3.5.21.40 CODESYS Control SL for Weidmuller u-OS-4.12.2.0 Controllers (Masters): Weidmuller UC20-M4000 ×2, configured as Active / Standby using CODESYS redundancy EtherCAT Slaves: Weidmuller UR20-FBC-EC ×3, supporting EtherCAT ring / line break detection Topology: EtherCAT ring (loop) Main question Is it officially supported to use: ・CODESYS PLC/Master redundancy (Active/Standby) and ・EtherCAT ring topology (for cable redundancy) at the same time? Expected behavior Our expectation is: ・When the Active PLC fails, the Standby PLC becomes Active ・The Standby PLC then takes over the role of EtherCAT Master ・EtherCAT communication is re-established ・I/O control continues after reinitialization (a short interruption is acceptable; no strict bumpless requirement) We do not expect completely seamless / zero-cycle switchover, but we want to understand: ・Whether this combination is supported by design ・Or whether there are known limitations or restrictions when EtherCAT ring mode is used together with Master redundancy Clarification At this stage, the question is mainly about feasibility and support, not about a specific error message yet. Any official guidance, limitations, or real-world experience would be greatly appreciated. Thank you in advance.

It's already fine to use, with help of exporting/importing as PLC_Open, at least CODEX is good in editing directly at XML and/or providing changes description separately.

You actually can use copilot by PLCOpen XML file exporting/importing. It's fine to work with it directly (at least, the Codex do it quite well).

Am I alone in this? Is this a known fault? Should I look for the reason of the lacking update option for "Control for linux SL" in my system or is it a potential fault in the codesys system?

If the Professsional Developer Edition (which includes the Test Manager) is not supported by Schneider, then an option is to use the Open Source Unit test framework. See: https://forge.codesys.com/lib/counit/home/Home/
