10 Monitoring
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 interruption of communication is controlled via the following settings:
1. During the initialisation of PROFINET communication the watchdog monitoring time spe-
cified 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 (Fieldbus status
displays ( 75)).
There is no response in the I/O device
.
2. To trigger a response in the IO device, you additionally have to set a Response of the
Inverter Drive 8400 (C13880
) under the Monitoring tab in the »Engineer«.
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 of monitoring will be 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]
" ( 83).
10.2 Interruption of internal communication
• The response in the event of a communication error between the communication module and
the Inverter Drive 8400 can be set via code C01501.
• The communication module reports a connection interruption to the IO controller and changes
to the "No_Data_Exchange" state.
