12.3 Troubleshooting for I/O Modules


The introduction of modules
Digital I/O modules, analog I/O modules, network modules, temperature measurement modules, and
motion control modules can be installed in an AH500 system. Please refer to AH500 Module Manual for
more information about the specifications for I/O modules. The error codes and the remedies for the errors
are listed below.
12.3.1 Troubleshooting for Analog I/O Modules and Temperature
Measurement Modules
Error
Description
code
The signal received by channel 0
exceeds the range of inputs
16#A000 which can be received by the
hardware. (The ERROR LED
indicator blinks.)
The signal received by channel 1
exceeds the range of inputs
16#A001 which can be received by the
hardware. (The ERROR LED
indicator blinks.)
The signal received by channel 2
exceeds the range of inputs
16#A002 which can be received by the
hardware. (The ERROR LED
indicator blinks.)

1. Check the communication setting in the master, and
the communication setting in slave 27.
2. Check the communication cable.
1. Check the communication setting in the master, and
the communication setting in slave 28.
2. Check the communication cable.
1. Check the communication setting in the master, and
the communication setting in slave 29.
2. Check the communication cable.
1. Check the communication setting in the master, and
the communication setting in slave 30.
2. Check the communication cable.
1. Check the communication setting in the master, and
the communication setting in slave 31.
2. Check the communication cable.
1. Check the communication setting in the master, and
the communication setting in slave 32.
2. Check the communication cable.
Remedy
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 0 exceeds
the range of inputs which can be received by the
hardware.
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 1 exceeds
the range of inputs which can be received by the
hardware.
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 2 exceeds
the range of inputs which can be received by the
hardware.
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 3 exceeds
the range of inputs which can be received by the
hardware.
