There are 6 standard LEDs for all SynqNet nodes, however some nodes may not visibly display all the LEDs. Be sure to consult your drive manufacturer to determine the actual LED locations.

LED1 - LED4 indicate network status. For any network fault, one or more LEDs will blink (No blink = normal operation).

LED5 indicates a node alarm by blinking (No blink = normal operation).

LED6 is for the FPGA boot status and is rarely used.

The location of each LED varies for each node type. Please contact the node manufacturer for details.

LED2
CYCLIC
ON = network cyclic
BLINK = network not cyclic
OFF  = power off, or reset
LED3
LINK_OUT
ON = receive valid (OUT port)
OFF = not valid, power off, or reset

REPEATER
ON = repeater on, network cyclic
BLINK = repeater on, network not cyclic
OFF = repeater off, power off, or reset
LED5
FPGA
ON = network cyclic
BLINK = network not cyclic
OFF = power off, or reset
LED6
BOOT
ON = loaded RUNTIME image into FPGA
DIM = loaded BOOT image into FPGA
OFF = not loaded, power off, or reset
