Monitoring

11.1

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 (

C13882

/

C14882

) 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

C13885

/

C14885

. (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 (

C13861

/

C14861

), and the red LED BE is activated (

Fieldbus

status displays

( 79)

).

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

(

C13880

/

C14880

) under the Monitoring tab.

In order to delay this response, you can set a monitoring time

(

C13881

/

C14881

).

• 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]

"
