A.4 Troubleshooting of I/O Modules

Introduction to troubleshotting modules
The following AS series modules can be installed in an AX-3 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.
A.4.1 Troubleshooting of Analog Modules (AD/DA/XA) and
Temperature Modules (RTD/TC)
A.4.1.1 ERROR
You can set up the option to be True in Module Alarm Setting to have the following errors appear as warnings when
they occur. Otherwise, when an error occurs, only an error message appears.

A.4.1.2
ERROR LED Indicators Blinking Every 0.2 Seconds
The following errors are specified as warnings to ensure that the AX-3 Series CPU can still run even when the warnings
are triggered by its AIO modules. If you need the CPU STOP running immediately when the first 4 errors occur, you need
to set the them as errors.
