一、桥式抓斗卸船机AC800M PLC控制系统通讯结构温州电厂5、6号桥式抓斗卸船机均采用ABB PLC控制系统,采用AC800M和支持Profi-bus-DP的CI851作为系统硬件的核心结构,用CI830和S800 I/O构成完整的硬件基础。在程序控制软件上使用3.2版本的ControlBuidder M。该控制系统采用双CPU控制器的配置,使用两个PM861对过程控制逻辑信号处理和传动系统调速分别进行控制,以保证系统控制响应的速度。整套系统共有5个远程I/O站,通讯模块选用CI851和CI830,控制器与I/O之间的连接分为两种:一是本地I/O,使用Modulebus(电气/光纤)通
First, the bridge grab ship unloader AC800M PLC control system communication structure Wenzhou Power Plant 5,6 bridge grab ship unloader using ABB PLC control system, the use of AC800M and support for CI851 Profi-bus-DP as the system hardware The core architecture, with CI830 and S800 I / O, forms the complete hardware foundation. Use ControlBuidder version 3.2 on program control software. The control system uses dual CPU controller configuration, the use of two PM861 process control logic signal processing and transmission speed control, respectively, to ensure that the system control the speed of response. There are totally 5 remote I / O stations in the whole system. The communication modules use CI851 and CI830. The connection between controller and I / O is divided into two types: one is local I / O, the other is Modulebus
