Hi!
Could you explain to me how to monitor the state of the ECC?
At the documentation page https://www.eclipse.org/4diac/en_help.php?helppage=html/development/forte_monitoring.html I could not find command to be used for this purpose.

I tried to use the keyword $ECC, but it didn't work out
Request:

<Request ID="14" Action="CREATE"><Watch Source="E_SR.$ECC" Destination="*" /></Request>

Response:

<Response ID="14" Reason="NO_SUCH_OBJECT" />

I attached the full Kotlin script that I used and corresponding output file.

Thanks in advance,
Daniil

Hi,

I think with all the updates we did on correctly handling IEC 61131-3 strings in 4diac FORTE we have problem that a $ is not a good qualifier any more. I guess we need to change that to something else. Maybe &.

Does anybody have an idea what would be good?

Cheers,
Alois

We probably want something which is an invalid identifier but not the escape symbol I guess?.

& would be ok, but is also and alternative for the AND keyword, so I would not take it if someone comes up with a good idea needing this. How about the exclamation mark "!" ? As far as I know, it is not used for nothing special in IEC 61131
