Hi All
Using Step 7, ladder logic. I need to program the following sequence:
If temperature starts to fall, open internal fuel gate to feed fuel.
So I need to operate a digital output based on a 'decline in temperature', any advice, please, on how to capture a decline in a set value? I guess I am looking for a Math function?
Cheers
