AH500 Hardware Manual

 After users set the PLC Link in ISPSoft, they can exchange the data with a device on the RS-485

network through the RS-485 serial control interface, and do not need to write any program.

(10) Hig

h-speed Ethernet communication interface

 AHCPU500/510/520/530-EN is equipped with a 10/100 M Ethernet communication interface, and

supports emails, webs, and socket services.

 After users set the Ether Link in ISPSoft, they can exchange the data with a device in the Ethernet

network 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.

(11) 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

the device

Parameter storage: The value in the device

Log storage: The system error log and the system status log

(12) Hot swap

 The AH500 series I/O modules support the on-line uninterruptible hot swap. When the system runs,

users can replace the module which breaks down without disconnecting the module. After the module

is replaced, the new module runs normally. Users do not need to set the module manually or switch

the state.

(13) Supporting the on-line debugging mode

 After a single instruction step has been complete, or after a breakpoint is specified, users can easily

find the bug in the program by means of the on-line debugging mode supported by the AH500 series

CPU module.

 If users want to enter the debugging mode, the CPU module must run. After users enable the on-line

monitoring function, they have to click

. The debugging screen varies from programming

language to programming language, but the same operation applies to these programming languages.

For the AH500 series PLC, structured texts do not support the debugging mode, and sequential

function charts support the debugging mode during the action and the transition.
