plc和dcs的区别

炒股赚钱平台1、CONGFAZHANDEFANGMIANLAISHUO:

DCS从传统的仪表盘监控系统发展而来。因此,DCS从先天性来说较为侧重仪表的控制,比如我们使用的YOKOGAWA CS3000 DCS系统甚至没有PID数量的限制(PID,比例微分积分算法,是调节阀、变频器闭环控制的标准算法,通常PID的数量决定了可以使用的调节阀数量)。 PLC从传统的继电器回路发展而来,最初的PLC甚至没有模拟量的处理能力,因此,PLC从开始就强调的是逻辑运算能力。

DCS在发展的过程中也是各厂家自成体系,但大部分的DCS系统,比如横河YOKOGAWA、霍尼维尔、ABB等等,虽说系统内部(过程级)的通讯协议不尽相同,但操作级的网络平台不约而同的选择了以太网络,采用标准或变形的TCP/IP协议。diangon.com这样就提供了很方便的可扩展能力。在这种网络中,控制器、计算机均作为一个节点存在,只要网络到达的地方,就可以随意增减节点数量和布置节点位置。另外,基于windows系统的OPC、DDE等开放协议,各系统也可很方便的通讯,以实现资源共享。
