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)
