FUNCTION_BLOCK ETrig EXTENDS EdgeTriggeredBehaviourModelBase IMPLEMENTS IETrig

This function block is a base implementation of a PLCopen Edge Triggered Behavior Model (see: IETrig). For use, this block should be extended and the specific inputs and outputs must be supplemented. The output eErrorID of the application-specific enum type ERROR must be added.

InOut:

Scope	Name	Type	Comment
Input	xExecute	BOOL	Rising edge: Starts defined operation FALSE: Resets the defined operation after ready condition was reached
Output	xDone	BOOL	TRUE: Ready condition reached
	xBusy	BOOL	TRUE: Operation is running
	xError	BOOL	TRUE: Error condition reached
