SAP PCo Acknowledge to OPC


Hi community,

we want to use the SAP PCo in our environement, our engineers think that there's probably a problem with using the PCo.

We want to trigger some MII transaction through the PCo by reacting on a single bit provided by the OPC server. I would suggest to use onTrue as TriggerType, but now how is the signal set back to 0 after triggering the MII, do I need to build a PCo Tag Query that sets back the bit in the OPC? Or is it better to set the signal automatically back after a certain time?

There seem to be some doubts about the reliability of the SAP PCo!

Maybe someone out there has a similar use case or a kind of Best Practive for such a scenario?
