- Scope - Name - Type - Comment - Input - xExecute- BOOLRising edge: Action startsFalling edge: Resets outputsIf 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. - 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
