10.1 Interruption of PROFINET communication
An interruption of PROFINET communication in the "Data_Exchange" state, e.g. by cable
break or failure of the I/O controller is recognised by the I/O device.

The response to the communication interruption is controlled via the following
settings:
1. During the initialisation of PROFINET communication the watchdog monitoring
time specified in the I/O controller ( C13882 ) is transferred to the I/O device.
If the I/O device does not receive any valid process data in the "Data_Exchange"
state, the process data are treated according to the setting in
C13885 . (Like this
the data that were sent last by the I/O controller can be used or set to zero.)
After the watchdog monitoring time has elapsed, the I/O device changes to the
"No_Data_Exchange" status (see C13861 ), and the red LED BE is activated ( LED
status displays
( 64)
).
There is no reponse in the I/O device.
2. To trigger a response in the IO device, you have to set a Reaction of the Inverter
Drive 8400 motec ( C13880 ) additionally in the »»Engineer«« under the
Monitoring tab.
By setting a Reaction time delay ( C13881 ) you can decelerate this response.
• In the Lenze setting "0 ms", this monitoring is activated.
• With the setting "65535 ms", this monitoring is deactivated.
• A change in the monitoring mode becomes effective immediately.
• The monitoring time elapses when the "Data_Exchange" status is exited.
After this response delay has elapsed, the response set is executed with the error
message " PROFINET: Data_Exchange status quit [0x01bc6531] "
