Status
When an IO Device is in Data Exchange with the PROFINET IO Controller
Unit to which it has been allocated, it will exchange input and output data
with the allocated memory of the PLC CPU.
OFF
ON
Note The bits for station 0 and 127 are not used.
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,

Unit operation
The IO Controller is not in Data Exchange with the
IO Device due to the fact that:
• the corresponding station does not provide data
at all.
• the corresponding station's inputs are invalid.
• the corresponding station is (another) IO
Controller station.
• the corresponding station is not allocated to this
IO Controller.
The corresponding station is in Data Exchange with
valid inputs.
