Status
If all Active IO Devices allocated to the CJ1W-PNT21 provide valid input
data, this flag will be ON. If one of the IO Devices does not provide data or its
data is marked as invalid, this flag will be OFF.

If all IO Devices allocated to the CJ1W-PNT21 have processed the sent
output data, this flag will be ON. If one of the IO Devices does not process
output data this bit will be OFF.

The IO Device Data Exchange Active flags indicate for each IO device if it is in
Data Exchange mode with the PROFINET IO Controller Unit. The flags are
allocated to a block of eight CIO words, and each bit in the block corresponds
to a IO Device number as set in the DTM (IO Device Setup tab).
