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

Inputs

Input	Data Type	Range	Unit	Default	Description

RST	BOOL				Reset to FALSE.

• 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.
