I want to monitor some tags change, then do some scripts.
if i have many tags want to monitor, I have to add many tag change scripts.
Is there another idea?
Today i find we can write scripts in tag or UDT tag.
When its value changed ,we can write scripts.
But has twoproblems:
one : when PLC restart, it will write first? How I avoid it?
Two: scripts can’t invoke gateway scripts ?How I invoke it?
