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" state (
), and the red LED BE is activated (
).
There is no response in the IO device.
2. To trigger a response in the IO device, the »Engineer« has to provide an additional Response
of the Servo Drive 9400
(
) under the Monitoring tab.
In order to delay this response, you can set a monitoring time
/
).
• 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" state is exited.
After this response delay has elapsed, the response set is executed with the error message
"
PROFINET: "Data_Exchange" status quit [0x00c88131]
.
