
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 and
control interface (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.
