Troubleshooting the OP-1212
33
I have configured the panel and connected it to my PLC. All of the lights are
flashing and nothing seems to work. What do I do?
D
Observe the TX and RX LEDs on the rear of the panel. If the TX LED flashes
but the RX does not, check all cables and connections and try again.
D
Examine the configuration and verify the Link and Comm. information match
the PLC type and family that you are using (i.e. baud rate, parity, stop bit,
address).
D
If you are using the secondary comm port on a
Direct
LOGIC PLC and both
TX and RX LEDs are flashing verify the mode of that port is set to HEX and
not ASCII.
D
If you are using a Allen--Bradley PLC, verify that the baud rate for channel 0
is set to 4800 or 9600 and the memory map has been expanded to include
the full range of registers (i.e., N7:0 through N7:7).
When I press a pushbutton nothing happens.
D
Verify that the control relays that you are using in your ladder logic match the
ones associated with the memory location that you mapped to the panel.
