
AHCPU500/501/510/511/520/521/530/531-RS2 provides two DB9 serial control interfaces, i.e. COM1
and COM2.

AHCPU500/501/510/511/520/521/530/531-EN provides one DB9 serial control interface, i.e. COM.

Users can set the DB9 serial control interface to RS-232, RS-485, or RS-422 according to the
application environment. The data transfer rate can be increased from 9600 bps to 1 Mbps.

AH500 basic series CPU module (AHCPU500/510/520/530): After users set the PLC Link in
NWCONIFG in ISPSoft, they can exchange the data with a device through the RS-485 serial control
interface, and do not need to write any program.

AH500 advanced series CPU module (AHCPU501/511/521/531): After users set the PLC Link in
HWCONIFG in ISPSoft, they can exchange the data with a device through the RS-485 serial control
interface, and do not need to write any program.
11. High-speed Ethernet communication interface

AHCPU500/501/510/511/520/521/530/531-EN is equipped with a 10/100 M Ethernet communication
interface, and supports emails, webs, and socket services.

AH500 basic series CPU module (AHCPU500/510/520/530): After users set the PLC Link in
NWCONIFG in ISPSoft, they can exchange the data with a device network through the Ethernet
communication interface, and do not need to write any program.

AH500 advanced series CPU module (AHCPU501/511/521/531): After users set the PLC Link in
HWCONIFG in ISPSoft, they can exchange the data with a device through the Ethernet
communication interface, and do not need to write any program.

The status or the error message related to the system is sent to users' email boxes immediately. Users
do not need to be on the spot to understand the problem.
12. Memory card

The memory card has the following functions.
System backup: The user program, the CPU parameters, the module table, the setting value in the
device
System recovery: The user program, the CPU parameters, the module table, and the setting value in
Parameter storage: The value in the device
Log storage: The system error log and the system status log
