FB_BA_CombinationBI_BV

The template is a combination of a BI and BV object.

The binary input object Input logs a binary input value from a bus terminal and outputs it as a boolean process value. In addition, the process value Input is output as a rising edge bTrigBI_PrVal.

The binary value object Value represents a boolean process value. It can be parameterized as a switch or push button by the parameter E_BA_ToggleMode. The output value of the Value object is also output as a rising edge bTrigBV_PrVal.

	The initialization of the template takes place within the method FB_Init.
