FLIPFLOPPLCopen motion icon

Function BlockClosedA function block groups an algorithm and a set of private data. It has inputs and outputs. - Flipflop bistable.

Inputs

IN  : BOOL Swap command (on rising edgeClosedA rising edge is the transition of a digital signal from low to high. It is also called positive edge)
RST : BOOL Reset to FALSE

Outputs

Q   : BOOL Output

Remarks

The output is systematically reset to FALSE if RST is TRUE.
The output changes on each rising edge of the IN input, if RST is FALSE.
