Post by nathant on Can't open online view of FB instance from code editor, only from Device/POU windows ^{CODESYS Forge talk (Post)}
Hello, The title pretty much says it all. When trying to open a FB from the CFC/Ladder/SFC editors while online, the FB does not open in an online view of that specific instance. Instead, it opens an offline view with '???' shown for the value of any variable. This makes debugging extremely cumbersome, as I have to find each FB in the POU window and select the specific instance I am trying to view. Anyone know the cause/solution for this? Thanks.

Hello I wouldn't call an FB from inside a FUN; it feels wrong to me. I have had something similar. Try declaring the FB instances as GlobaVars rather than the instance memory.

Post by andrej on POU - Access to runtime ^{CODESYS Forge talk (Post)}
Hello all, when creating a POU, the Codesys IDE allows the setting "Enable System Call" (in the Settings, Property -> Build), see picture. The name suggest, that runtime functionalities i.e. functions of codesyscontrol such as "stop plc" etc. can be directly called. I tried various approches without success, the following does, unsurprisingly not work. FUNCTION accessRTE: BOOL; ****************************** codesyscontrol.stop(); Can you please tell me how I can make a system call to codesyscontrol from a POU. Or could you provide me with a use case for this setting. Many thanks for your feedback and kind regards Andrej
