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]

" ( 71).
