ETrigTo (FB) ¶ FUNCTION_BLOCK ETrigTo IMPLEMENTS IFBCommand Serves as a basis for E dge Trig gered, T ime o ut constrained 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. 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

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

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

Helper ¶ DecodeClass (Function) DecodeEvent (Function) EncodeSpec (Function)

DecodeClass (FUN) ¶ FUNCTION DecodeClass : EVENT_CLASS This function serves to extract the vaue eClass of type EVENT_CLASS from parameter dwSpec of the callback function. InOut: Scope Name Type Comment Return DecodeClass EVENT_CLASS The EVENT_CLASS of dwSpec. Input dwSpec DWORD A combination of EVENT and EVENT_CLASS

DecodeEvent (FUN) ¶ FUNCTION DecodeEvent : EVENT This function serves to extract value eEvent of type _Event from parameter dwSpec of the callback function. InOut: Scope Name Type Comment Return DecodeEvent EVENT The EVENT of dwSpec Input dwSpec DWORD A combination of EVENT and EVENT_CLASS

EncodeSpec (FUN) ¶ FUNCTION EncodeSpec : DWORD This function servers to create the parameter dwSpec of type DWORD, which is necessary for callback functions, out of two values of type EVENT and EVENT_SOURCE . InOut: Scope Name Type Comment Return EncodeSpec DWORD Input eEvent EVENT Event to be used eClass EVENT_CLASS Event class to be used
