I have a single boolean tag I'm reading from a plc. I setup a transaction group with 4 basic opc/group items: the boolean tag listed twice, one tag to store the value for the hour meter, one tag to store value for the counter. I made 8 groups exactly like this. When I look at the tx group, specifically the bool tags, I see a value on one of them and "Bad_Stale" for the others value but its the same tag. Please help.
