Hi,
I am trying to set up a derived tag that gets its state from an expression looking at a number of very similar Tag Names, eg all start with CC_888_.
There is such a vast number of tags across various PLC's that I am trying to simplify the expression to save on arduous repetitive work. I am trying to do an expression using address for each PLC featuring a wildcard of the tag name that is similar.
So the expression appears like
If {/Data::[16_5_PLC1]*CC_888_*} >0
Then 1
Else 0
Is it possible to wildcard on derived tags in this way so that the tag will check all tags startiing with that text in the PLC address?
Thanks in advance.
