[Question] Is there any standard way to query a PLC for its current program version or checksum? #51

(This is not an issue for Sally per se, but a question related to Sally7 devs and users field of work)

I would like to track if any changes or incompatibilities could happen between the programs I develop in C# using Sally, and the PLCs I communicate with.

Is there any standard way to query a PLC for its current program version or checksum?

I searched existing discussions and documentation without finding anything useful so far:

Is the function GetChecksum good enough for this usage? How would I call this function with Sally?

Hi @Thieum, sorry for the late reply. I don't see any implementation of GetChecksum, only a mention of it's existence. If there's an implementation, I imagine I could add it to Sally7.
