ETrigToTl (FB)¶

FUNCTION_BLOCK ETrigToTl IMPLEMENTS IFBCommand

Serves as a basis for Edge Triggered, Time out constrained, Time limited function blocks

InOut:

Scope	Name	Type	Comment
Input	xExecute	BOOL	Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError) are present at the outputs for exactly one cycle.
	udiTimeLimit	UDINT	Defines how long (µs) an FB (requiring a long time for complete processing) may run until it is forced to return to the calling POU. The value 0 means that there is no time limitation.
	udiTimeOut	UDINT	Defines the time (µs) after which an FB (e.g. requiring an external acknowledgement) aborts operation due to a timeout with error message.
Output	xDone	BOOL	TRUE: Action successfully completed
	xBusy	BOOL	TRUE: Function block active
	xError	BOOL	TRUE: Error occurred, function block aborts action FALSE: No error
