44 PLC-5 Ethernet Interface Module

Publication 1785-IN019B-EN-P - January 2007

Monitor the series of blinks to determine the fault code. Count the first and last series of slow

blinks, and disregard the series of fast blinks between the slow series.

Module Error Codes

When the status LED blinks red, it signals that a hardware or software fault has been detected

and it reports the error via a code. This code is a two-digit fault code signaled by a flash

sequence. First, the LED begins the sequence with 10 rapid flashes. Then the LED signals the

first digit of the code by a number of slow flashes. Approximately two seconds after the LED

displays the first digit, the LED displays the second digit. This sequence repeats itself until the

module is either reset or replaced.

The following table lists controller fault codes relating to the interface module.

IMPORTANT

The interface module will flash the indicator lights as shown in the

Module Error Codes table. The controller may fault even though the

module does not.
