Hey guys,
I'm pretty new to all that PLC stuff.
I wonder how I can check wether 2 inputs just became positive.
For example, I/0 AND I/1 are on in the same scan.
I want to check if they became on this scan and power an output as long as they're both still on.
But, if one of them is on without the other, or they're both on but didn't do this in the same scan, I don't want to power that output.
I hope my explanation is clear enough. If not, I will try again.
Thanks,
Yair.
