1.2 Overview
An AH500 series CPU module is a medium type of advanced controller with built-in communication ports. It
provides a strong network function for users, and users can create connection among devices on the network
through software. An AH500 series CPU module also provides structured programming. Users can assign
programs to different tasks, and write a program which is frequently executed in a function block. Besides,
users can choose different programming languages (instruction lists (IL), structured texts (ST), ladder diagrams
(LD), sequential function charts (SFC), and function block diagrams (FBD)) dealt with by IEC 61131-3
according to their needs when writing programs. They can create the AH500 hardware configuration by means
of hardware configuration software. They can also restore or back up a system rapidly through the built-in SD
interface in an AH500 series CPU module. This manual introduces the basic operation of an AH500 system,
and help users familiarize themselves with the AH500 system.
Built-in with multiple communication interfaces, AH500 series CPU module provides user-friendly setting
environment for users to create connections with devices easier and more rapidly. Users can restore or back
up a system rapidly through the built-in SD interface in an AH500 series CPU module.
An AH500 series CPU module provides structured programming. You can assign programs to different tasks.
