Hi, I want to initialise some tags on first scan only. As they are related to wall-clock time, I want to do the initialisation when the PLC first goes into RUN mode, rather than give the tag a 'start up' value in the datablock.
Is there a built-in tag that I can use for this?
I *think* it might be %M0.0 but I'm not sure.
Thanks
