Using Ladder Logic to control output8?

Post by FullWindsor »

So what i am trying to achieve here is that whenever output 0-3 are on i also want output 8 to turn on. output 0-3 are valves controlling coolant flow to fermenters. Output 8 it the pump for the coolant.

here is my logic set up

What more do i have to do to get that output to fire once one of the others do?

Output8 needs to be in the last column. That should probably be clarified in the UI.
