Device
ALWAYS make sure the IO Device Data Exchange Active flag is ON before processing
the slave's input data. The last data from the slave will remain in the PLC memory if
data exchange is stopped,
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).

The bits for station 0 and 127 are not used.

Unit operation
No new IO Device Alarms have been received.
One or more new IO Device Alarms have been
received.
This bit will be set to OFF by the Unit.
Unit operation
The IO Controller is not in Data Exchange with the
IO Device due to the fact that:
•
•
•
•
The corresponding station is in Data Exchange with
valid inputs.

the corresponding station does not provide data
at all.
the corresponding station ’s inputs are invalid.
the corresponding station is (another) IO Control-
ler station.
the corresponding station is not allocated to this
IO Controller.
