8 Monitoring
Interruption of POWERLINK communication
An interruption of POWERLINK communication in the OPERATIONAL state, e.g. by cable break or fai-
lure of the managing node, is detected by the controlled node. The response to this interruption of
communication depends on the following settings:
1. The watchdog monitoring time defined in the managing node is transferred to the controlled
node when the POWERLINK communication is initialised.
If the controlled node being in the OPERATIONAL state does not receive valid process data, the
process data are handled according to the setting in C13885 . (The last data sent by the mana-
ging node can either be used or set to zero.)
If communication fails, the controlled node state changes to PRE-OPERATIONAL (see
C13861 )
and the red LED "BE" is activated (see Fieldbus status displays
(

54)
).
By default, there is no response in the controlled node.
2. To cause a response by the controlled node, you additionally have to ...
• set a response of the controlled node ( C13880/1 ).
