I am working on a safetyPLC project and need the use of EVL/EVC to share variables between safetyPLC and non safe PLC side.
Recently we discovered that function blocks instances have some additional safety requirements that would we have to fulfill, but since we only use these blocks once it made sense to change to all to PRGs instead.
After changing them all, the EVC list stopped displaying the variables, it seems that there are too many PRGs for it to handle. The code still works, but I can't add new variables through the GUI now, it just shows blank.
I'm using CODESYS 3.5 sp11.
Are there any workarounds to this?
For now I think I will have to open an old version with FBs that worked, share variables only through GVL and then copy this evc to the new project with the PRGs.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
