It would be nice if I could tell FSQL to ignore a tag in a group that is being monitored for changes. In a group monitoring the set points of a machine, I’d like to be able to write a 1 to a bit if any of the set points changes. I would like to use the handshake option to do this. The problem is that if the “success” bit is in the group, the group will trigger when it writes a 1, so I get two triggers and the “success” bit will never go low again. To get around this I had to make two groups. The first monitors the set points and an action item writes a 1 to a SQL table. The second group monitors that table and when it sees the 1, triggers. This is pretty round about, but it works for now.
I would think this feature wouldn’t be too complicated to include.
