12.3
Troubleshooting for Other I/O Modules
Introduction to troubleshotting modules
Digital I/O, analog I/O, temperature measurement, positioning, counter, load cell, and network modules can be
installed in an AS Series system. There are 2 types of error codes; error and warning. The CPU module and its
modules stop operating when errors occur. The CPU modules and its modules do not stop operating when warnings
are triggered.
12.3.1
Troubleshooting for Analog Modules (AD/DA/XA) and
Temperature Modules (RTD/TC)
12.3.1.1 ERROR LED Indicators Are ON
You can set up HWCONFIG to have the following errors appear as warnings when they occur. Otherwise, when an error
occurs, only an error message appears.
Error
Description Solution
16#1605 Hardware failure
If the problem persists, contact the local authorized
distributors.
16#1607 The external voltage is abnormal. Check the power supply.
16#1608
The factory calibration or the CJC is
abnormal.
If the problem persists, contact the local authorized
distributors.
12.3.1.2 ERROR LED Indicators Blinking Every 0.2 Seconds
The following errors are specified as warnings to ensure that the CPU can still run even when the warnings are triggered
by its modules. If you need the CPU STOP running immediately when the first 4 errors occur, you need to set them as
errors.
Error
Description Solution
The external voltage is abnormal.
