Processing details
• This instruction changes the communication protocol, transmission setting, or station number of each channel of the
module specified by (U).
• The completion status of the ZP.UINI instruction can be checked with the completion device (d) and the completion status
indication device (d)+1.
• Completion device (d)
This device turns on during END processing of the scan where the ZP.UINI instruction completes, and turns off during the next END processing.
• Completion status indication device (d)+1
This device turns on or off depending on the completion status of the ZP.UINI instruction.
When completed successfully: The device remains off.
When completed with an error: The device turns on during END processing of the scan where the ZP.UINI instruction completes, and turns off during the next
END processing.
• The following figures show how the ZP.UINI instruction operates when its execution completes.
