Verifying Proper Power-Up of the CMM742
After configuring the Interface, follow the procedure below to verify that the Ethernet Interface is
operating correctly.
1.
Turn power OFF to the PLC for 3–5 seconds, then turn the power back ON. This will
initiate a series of diagnostic tests.
The MODULE OK LED will blink indicating the progress of power-up.
2.
The LEDs will have the following pattern upon successful power-up. At this time the
Ethernet Interface is fully operational and on-line.
LED
Ethernet Interface Online
MODULE OK
●

●/✲ (ON/Traffic)
SERIAL ACTIVE
❍
(OFF)
STATUS

If the STATUS LED is OFF, check the PLC Fault Table. Alternatively, use the Station
Manager LOG command as explained in GFK-1186, TCP/IP Ethernet Communications
for the Series 90 PLC Station Manager Manual
.
Problems During Power-up
If a problem is detected during power-up, the Ethernet Interface may not transition directly to the
Operational state. If the Interface does not transition to Operational, check the LED pattern on the
Interface and refer to the following chart and table for corrective action.
