Interruption of Ethernet POWERLINK communication
An interruption of Ethernet POWERLINK communication in the OPERATIONAL state, e.g. by
cable break or failure 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 Ethernet 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 managing 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
( 55)
).
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 ).
