You only need to create a single library because CODESYS will recompile it for each 32-bit or 64-bit target on import, as long as you only use pure IEC/ST and neutral types like __XWORD, __XINT, __UXINT. Pointer arithmetic can be done by casting the pointer to __XWORD then adding the offset and casting it back, e.g. pNew := POINTER_TO_BYTE(__XWORD(pBase) + offset). https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_library_development.html Wheelie Life Avoid using UDINT/DWORD to hold the address as it will crash on 64-bit. Only if you use external C code or an architecture-dependent binary will you need two copies of the library; otherwise one is sufficient and portable.

Problem was solved by installing a package manager.

Unhandled exception and refactoring error

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.

Hello, this has been happening to me too since I updated to SP21 Patch 4. It seems the problem is on my main computer (Desktop) but not on the laptop. Has anyone found the cause? Thanks

Let's say I have a CODESYS controller (PLC) with a runtime version around 3.5.19. If I use development software version 3.5.21.40 or a later version that will be released in the future for programming, could there be any problems or malfunctions in the controller's program execution or in the execution of the new, updated function blocks from the newer software? I mostly work with servo-based motion applications, so please keep that in mind when answering, and provide a detailed answer so I don't have to email you again about this topic.
