Interruption of PROFINET communication
An interruption of PROFINET communication in the DATA_EXCHANGE state, e.g. by cable
break or failure of the IO controller is recognised by the IO 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 IO controller is transferred to the IO device.
If the IO device does not receive any valid process data in the DATA_EXCHANGE
state, the process data are treated according to the setting in
. (Like this
the data that were sent last by the IO controller can be used or set to zero.)
After the watchdog monitoring time has elapsed, the IO device changes to the
NO_DATA_EXCHANGE status (see
), and the red LED "BE" is activated
There is no reponse in the IO device.
2. To trigger a response in the IO device, you have to set a Response of the Inverter
Drive 8400
) additionally in the »Engineer« under the Monitoring tab.
By setting a Reaction time delay
) you can decelerate this response.
The response delay elapses when the DATA_EXCHANGE status is exited.
After this response delay has elapsed, the response set is executed with the error
PROFINET: Data_Exchange status quit [0x01bc6531]
