Troubleshooting the OP-1212 Panel
This section is intended to help you through some typical situations that might occur
while using the OP-1212. It is difficult to diagnose or solve all probable situations that
may arise, therefore this section will discuss some of the more common trouble
areas.
To help isolate the problem area, these problems have been divided into three
sections:
D
Panel Configuration
D
Panel to PLC Communications
D
Panel Operation
If you continue to have a problem after applying this section, please contact our
Technical Support team. Someone will be available between 9:00 am and 6:00 pm
(EST) Monday through Friday. Phone

.
When I try to download the configuration, the message ”could not
communicate with panel” appears.
D
Examine the two LEDs on the rear of the panel that show the state of the
communication link. If the RX LED blinks but the TX LED does not, verify that
you are using the appropriate cables.
D
If the RX LED does not blink, the communication cable is plugged into the
wrong serial port of the PC, the cable is faulty, or the panel is faulty.
D
If the TX LED and/or the RX LED is blinking very slowly while you are
attempting to download and all of the Lamps and LEDs are blinking, verify
that the panel address is set to 31 (all positions ON) and power cycle the
panel.
