4-2 Communicating via the Interface Module

Monitor the series of blinks to determine the fault code. Count the

first and last series of slow blinks, disregarding the series of fast

blinks between the slow series.

Important: The interface module will flash the indicator lights as

shown in Appendix D. The processor may fault even though the

interface module does not.

The table below lists all major processor fault codes pertinent to a

sidecar module, such as the Ethernet interface module. For a

complete list of fault codes for PLC-5 processors, see the Enhanced

and Ethernet PLC-5 Programmable Controllers User Manual,

publication 1785-6.5.12.

Fault-code dependent See Appendix D

Off Ethernet interface is functioning

properly but it is not attached to

an active Ethernet network

Normal operation Attach the processor and

interface module to an

active Ethernet network

Green Ethernet channel 3A is

functioning properly and has

detected that it is connected to an

active Ethernet network

Normal operation No action required

XMIT Green Lights (green) briefly when the

Ethernet port is transmitting a

packet. It does not indicate

whether or not the Ethernet

Port is receiving a packet.
