PLC Based Control System for a Pump StationTomáš Polák
所幸,这时国际上也开始兴起了开放式系统的浪潮,涌现出了一批热衷于开放式系统的公司(但没有一家是有名气的大公司)。该系统一开始曾经受过日本横河公司的CENTUMCS的概念的启发,也考虑了ROSEMOUNT的DELTA-V的现场总线与PC-BASED的合一的开放概念,也参考过美国OPTO22的SNAPI/O系统的带有以太网接口的I/O模块,但上述系...
谈到PC-Based控制器,首先要明确PC的定义。狭义的PC指的是x86硬件+ Windows操作系统,这种情况下PC-Based控制器的下面两层就是x86硬件+ Windows操作系统(带实时扩展),典型的PC-Based控制器有Beckhoff的CX1000/CX2000/CX5000/IPC+TwinCAT, Siemens的WinAC RTX,CODESYS Control RTE SL等。更宽泛定义的PC-Based控制器...
PAC(可编程化自动控制器,programmableautomationcontroller)的概念定义为:控制引擎的集中,涵盖PLC用户的多种需要,以及制造业厂商对信息的需求。PAC包括PLC的主要功能和扩大的控制能力,以及PC-based控制中基于对象的、开放数据格式和网络连接等功能。从技术层面分析,PAC是一种总线型分布式控制系统,PAC系统总线技术作为工业现场...
Aerodynamic brake control system with an emergency button, with emergency reset function. 空气动力制动控制系统设有网络传输功能,通过该网络可以任意组合多个空气动力制动控制系统,且具有主从选择功能. Aerodynamic brake control system is provided with network transmission function, which could be a combination of...
在超过半个世纪的发展历程中,PLC不仅没有被竞争者PC-based、PAC替代,还在与时俱进,不断演进发展,囊括了工业生产所需的逻辑控制、顺序控制和运动控制(以及三者的复合应用)功能,并向过程控制领域不断延伸。它所代表的简易、可控、稳定、高效时至今日都是企业生产作业的基本要求。本文将详细梳理PLC的发展历程,总结其...
