Hi Guys,
I'm converting a Zelio program (in FBD) to an M221 (Ladder) and having a brain issue.
I am monitoring two analog inputs. When both analogs are above a set value for a set time, I want to energise an output. In the Zelio, I used a Schmitt trigger so I had hysteresis (deadband), but am unsure how to achieve this in ladder in the M221.
Any help would be greatly appreciated.
