In the tag group editor there is a "read after write" option in the "OPC Setting".
Is the "read after write" supporsed to mean read the OPC PLC value after the Ignition tag has been written to? Or has it something to do with the OPC-UA module writing to the tags in the PLC and then read after that? What triggers the read after write action?
How does "read after write" behave when the tag group is set on a memory tag with no OPC comminucation?
If I have a bunch of memory tags and OPC tags and I just want them to "update" their values when they are wirtten to from an Ignition designer or client, because I know that is the only time they change, how would I best set up the tag group for them?
