ONWORKS service LED
case When can it occur? meaning remedy
1
Anytime
Node is configured and running normally
No action necessary
2
Power up of controller
Bad node hardware
► Replace hardware
3
Power up of controller
Bad node hardware
► Replace hardware
4
Power up / reset
Node lacks application.
May be caused by neuron chip firmware when
a mismatch occurs on application checksum
► Using EXCELON, set module to
