Fieldbus Status - WAGO LONWORKS 750-319 Manual

3.1.7.2 Fieldbus status

The operating status of the communication via LON is signalled via the top
LED group (SERVICE, STATUS and ICOM).
The SERVICE LED is directly connected to the Service Pin of the Neuron
Chip and indicates the state of the Neuron-C application.

The STATUS LED indicates that a coupler is activated. This is the case when
a wink task is sent and when the communication of both network manager and
DPRAM interface fails.

Trouble shooting
Press the Service-Pin of the coupler and check
the Neuron-C application.

Check the Neuron-C application, if necessary
restart the application.
Trouble shouting
Reset fieldbus coupler hardware by switching off
the supply voltage of the coupler for about 3
seconds.
Change the fieldbus coupler if necessary.
Trouble shooting
Check bus system integrity
