PM864AK01 3BSE018161R1应用DCS冗余CPU控制器ABB模块

AC 800M 控制器由安装在水平 DIN 导轨上的若干单元组成。DIN 导轨，可安装在机箱内。大多数装置包括一个底座安装板和一个用螺钉固定的可拆卸模块。构成 AC 800 M 控制器的硬件单元包括

- 中央处理器单元（CPU）

- 用于不同协议的通信接口模块

- S800 输入/输出模块

- 电源模块

各种 I/O 系统可直接（S800 I/O 或通过 PROFIBUS 或 FOUNDER）连接到 AC 800M 控制器。(S800 I/O）或通过 PROFIBUS 或 FOUNDATION 连接。CPU 由一个底板 TP830（接线板）和一个处理器模块 PM8XX 组成。PM8XX 具有不同的速度和内存组合。底板 TP830 承载着与处理器、电源、通信接口以及外部总线的大部分连接。电源和通信接口以及外部总线的大部分连接。

S800 I/O is a distributed and modular I/O system that communicates with controllers over PROFIBUS-DP/DPV1 or direct (via Modulebus). The S800 I/O system is DIN rail mounted and consists of Fieldbus Communication Interfaces, Modulebus Modems, S800 I/O modules and Module Termination Units (MTU). S800 I/O modules (not S800L) are mounted on MTU&＃39;s, this makes them hot-swappable. Depended on the mounting requirement (horizontal or vertical) and on the field termination needs (powering, fusing etc.) there are numerous of MTU&＃39;s to choose from. The S800 I/O system supports fully redundant applications, redundancy can be built in on both communication level and I/O module level. S800 I/O connected with PROFIBUS- DP/DPV1: ? Field Communication Interface CI801 or CI840 is the I/O station master ? Maximum 24 I/O modules per I/O station ? 1 base I/O cluster with up to 12 I/O modules (connected via electrical Modulebus) ? 1-7 additional I/O clusters with up to 12 I/O modules per cluster (connected via optical Modulebus using Modulebus Modems)
