Controller LEDs
See Also: Node LEDs
SynqNet
SynqNet controller LEDs will BLINK to indicate a fault (or undiscovered network). A controller with no blinking LEDs is in normal cyclic operation (without faults). Each SynqNet port has two LEDs. And each LED has a particular function, which is described in further detail below.
Each controller will have four green LEDs:
LED1 and LED3 = Link Activity
- On (Link Active)
- Off (Link Inactive)
LED2 and LED4 = Network Activity
- On (Cyclic Phase--Tx and Rx are Active)
- Off (Shutdown Phase--Idle State or network reset)
- Blink (Discovery Phase--only Tx is Active)
CAN
The XMP-CAN controllers have two green LEDs. These LEDs give a visual representation of the activity on the CAN network. The locations of the LEDs vary depending on the type of XMP-CAN controller. The photos and table below show the locations and meanings of each LED.
