FUNCTION_BLOCK SETIO_PART
The SETIO_PART function block sets the output data for a subset of the output data associated to a slot or subslot of a Field Device. The output data are addressed within the slot or subslot through the OFFSET and LEN parameters. The SETIO_PART function block sets the output data to the Host Controller interface into the cyclically written output data of the Field Device. The function block is invoked by a 1 of the EN input. If the Output data are stored successfully and the Field Device is still cyclically communicating, the ENO output is set to 1.
If the Output data are stored successfully and the Field Device is still cyclically communicating, the ENO output is set to 1
Never use GETIO-/SETIO_PART FBs concurrently with %I/%Q-Input/Output-Mapping for the same slot/subslot !
