Function Block FFS

The Function Block FFS is a Flip-Flop switch with toggle input.

Input TR

This is the push button input. This toggles the output Q between true and false on a positive edge.

Tip: If this should happen on a negative edge, use the Function Block N before the input.

Input SET1

If this input is true, then the output Q is held at true. This input has priority over the input RESET.

Input RESET

If this input is true, then the output Q is held at false.

Output Q

The output toggles between true and false. This is true when SET1 and RESET are true.
