Post by imdatatas on MC_MoveAbsolute: C0138: No matching 'FB_Init' method found for instantiation of SMC_MoveAbsRelPerformerImpl [ERROR] ^{CODESYS Forge talk (Post)}
Dear @gseidel, Thank you for your reply. The exact version of Codesys and its compiler was 3.5.21.20. The compiler version was fixed and could not be changed in project settings. Since I couldn't continue due to this compilation error, I temporarily overcame this issue as follows. -- I completely uninstalled Codesys 3.5.21.20 and completely deleted the Codesys folder in the C:\ProgramData folder. -- I restarted my computer and installed Codesys 3.5.19.70. -- I updated the Codesys Installer and all its add-ons to the latest versions. -- The project that was giving me the compilation error I mentioned before is now open with Codesys 3.5.19.70, compiled it, and successfully downloaded it on the device. -- I haven't encountered the same problem anymore. I think this issue is related to SP21 and its compiler. Frankly, I'd expect a project created with an older version to compile without errors after opening it with the latest Codesys version and updating all libraries. Regards, imdatatas

Post by tomast on Codesys and Siemens SINAMICS 20 modbus RTU "Response CRC Fail" ^{CODESYS Forge talk (Post)}
Hi everyone, I'm currently working on a project involving the control of 5 VFDs via Modbus RTU, this time using the WAGO 750-8212 CPU. So far, I've managed to make progress, but I've encountered an issue. While I can successfully read and write to all the registers I need, I consistently encounter a "Response CRC Fail" error when attempting to write the value 1151 to the STW register at address 40100. I'm able to set the frequency via register 40101 and adjust all other parameters using different registers. Setting STW to 1150 results in the drive ready boolean from the ZSW-bit being received instantly. However, the moment I attempt to send 1151 to register 40100, I immediately receive the "Response CRC Fail" error for all channels. I've also attempted to use combined control, employing Modbus for frequency control and starting from a digital input. Everything seems to function properly until I send the start command to the VFD. Interestingly, I consistently encounter the same error the moment I send the start command, regardless of whether I use register 40006 (high) or 40100 (1151). Could someone please assist me in resolving this issue?

Post by rk-gaw on Unhandled exception and refactoring error ^{CODESYS Forge talk (Post)}
Hello everyone. I hope this is the right place to ask for help, this error is causing me a great amount of time loss and I really would like to end this nightmare. I don't know why but at times if I try to Browse -> Display Cross Reference on a variable Codesys just crashes. I'll attach the file with the complete crash report hoping someone can figure why it happend. I think that the unhandled exception comes from the PersisranceManager Module and is connected with the other big problem I'm facing: I cannot refactor in my project, if I'll try to refactor a POU name the whole POU will become "frozen", it's like its desynchronizing from the project and the project cannot find the pointer to the POU once I refactor it. And when I open the project a warning pop-up will show up with the frozen POUs name, but I cannot figure out what the warning is telling me. I'll attach every warning and error pop up the project is showing me, and thanks in advance to anyone who can figure something out.
