ETrigToA (FB)¶
FUNCTION_BLOCK ETrigToA IMPLEMENTS IFBCommand
Serves as a basis for Edge Triggered, Time out constrained, Abortable function blocks
- InOut:
- 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.- xAbort- BOOL- TRUE: Action is stopped immediately and all outputs are reset to their initial values.- 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- xAborted- BOOL- TRUE: Action aborted by user
