FB_BA_Toggle

The function block is used to switch an actuator on or off.

The input bEn is used for enabling the function block.
A positive edge at the input bOn results in setting of output bQ. The output is reset by a rising edge at the bOff input. If a rising edge is presented to bToggle, the output is negated; i.e., if On it goes Off, and if Off it goes On.
