AH500 Module Manual
8-22
Additional remark:
1. If the values in m
1
and m
2
exceed the range, the operation error occurs, the instruction is not
executed, SM0 is ON, and the error code in SR0 is 16#2003.
2. If S~S+n-1 exceed the device range, the instruction is not executed, SM0 is ON, and the error
code in SR0 is 16#2003.
3. If the value in n exceeds the range, the operation error occurs, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#200B.
4. Due to the fact that the use of the instruction TO decreases the execution efficiency of the CPU
module and that of the I/O module, users should use it less often.
5. The descriptions of the error codes:
16#2003
Please refer to point 1 and point 2 in the
additional remark.
16#200B
Please refer to point 3 in the additional
remark.
16#1400
An error occurs when the data is
accessed through the auxiliary
processor.
16#1401
An error occurs when the data in the I/O
module is accessed.
16#1402
The arrangement of the I/O modules is
not consistent with the module table.
16#1407
A communication error occurs when the
data is accessed through the auxiliary
processor.
8.5 Quick Start
This section introduces how to carry out the Modbus RS-485/RS-422/RS-232 communication
through a communication port on AH10/15SCN-5A.
Setting communication
After users double-click the module AH10/15SCM-5A in the HWCONFIG window, they can set
COM1 and COM2 in the Parameter Setting window
Start ISPSoft, right-click the module in the HWCONFIG window, click Intelligent Module
Configuration on the context menu, and click Yes. SCMSoft is started.
