Output Coil

The basic type of output coil is controlled by conditional logic within the same rung. When the coil receives power flow from logic to its left in the rung, the reference associated with that coil is set to 1. When no power flow is received, the reference is 0.

The state of output coils may also be affected if they are between an MCR/End MCR coil pair or a Skip/End coil pair, as explained on the following pages.
