描述
从系统的可扩展性和兼容性的方面来说。
市场上控制类产品繁多,无论DCS还是PLC,均有很多厂商在生产和销售。对于PLC系统来说,一般没有或很少有扩展的需求,因为PLC系统一般针对于设备来使用。一般来讲,PLC也很少有兼容性的要求,比如两个或以上的系统要求资源共享,对PLC来讲也是很困难的事。而且PLC一般都采用专用的网络结构,比如西门子的MPI总线性网络,甚至增加一台操作员站都不容易或成本很高。
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,比如西门子、ABB、霍尼维尔、GE、施耐德等等,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。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。
3、从数据库来说。
DCS一般都提供统一的数据库。换句话说,在DCS系统中一旦一个数据存在于数据库中,就可在任何情况下引用,比如在组态软件中,在监控软件中,在趋势图中,在报表中……而PLC系统的数据库通常都不是统一的,组态软件和监控软件甚至归档软件都有自己的数据库。为什么常说西门子的S7 400要到了414以上才称为DCS?因为西门子的PCS7系统才使用统一的数据库,而PCS7要求控制器起码到S7 414-3以上的型号。
