AC500 是ABB 公司推出的一款可升级的和灵活的自动化控制系统，可完美地满足客户需求。此系统采用了底板上组合模块的结构。
不同系列的CPU 模块（PM571、PM581/582 和PM590/591）插在通用的CPU 底板上，CPU 底板上的通讯扩展槽数分为1、2、4 三种（TB511、TB521 和TB541）。S800 I/O是一种全面分布式的模块处理I/O系统，它通过工业标准的现场总线将主控制器与PLC（程序逻辑控制系统）联系起来，由于其具有广泛的连通性，它适用于ABB和其他厂家生产的各种处理控制器和PLC.由于可以现场安装，靠近感应器和传动器，
S800 I/O通过降低铺设电缆的成本来减少安装成本，由于具有模块“热插拔”，“飞跃”重新配置和冗余选项等特点，S800 I/O因而可促进产量，增加利润．
ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.
PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different),
Each card is connected to a fieldbus to collect process data and diagnostic information from the bus. The interface card is easy to replace and plug and play
(plug & play) and can be plugged in and out with power.
The field controller PS has the following features:
o
Flexible: it supports all international standard open fieldbus and can be mixed
4 high-speed fieldbuses can be connected at the same time (max. 12 MBD)
Simple project: only use the same tool CBF (control build f) software for configuration, debugging and diagnosis
