GE GFK-0804B manual Skip/End Coil Pair

Skip/End Coil Pair

The Skip/End coil pair can be used to cause one or more outputs in the program to stay in their current state (1 or 0), regardless of the state of any inputs or other conditional logic to those outputs. The rungs with the outputs to be controlled must be located between the Skip coil and its paired End coil in the program.

In the example below, the Skip and End coil control the states of outputs O17 and O18. While the Skip coil receives power flow from its conditional logic (in the example, it is contact I1), all output coils within the Skip/End pair hold their last states.

This is a Skip to END operation. When input I1 is 0, the Skip command is not performed.

When input I1 is 1, all outputs till END are on hold, and are not affected by input conditions.
