A4H124-24TX P0973JM 以太网交换机Enterasys系列工控品质备件
仅使用模块化PLC控制器和HMI操作员面板。根据公认的假设，该系统应执行功能类似于DCS系统，但由于程序限制是不可能完成所有功能的。设计的系统分为分配了以下设备：TIA Portal V13软件到工程层；工艺层的两个PLC S7-1200；HMI KTP 700基本面板至操作员层；SCALANCE XB005接口提供使用以太网的所有设备之间的通信通信层；嵌入控制器数字和模拟输入和输出，其精度在保持某些指导方针的同时确定输入和输出层。分布式控制系统的模型生产线。建议的系统（图1）用于控制生产线模型，冗余度为由于使用了两台西门子S7-1200控制器。主控制器是PLC1，其任务是以在典型的操作条件下控制该过程。从控制器是标记为PLC2的设备任务是在PLC1时刻接管控制与使用PLC控制器有关的问题分布式控制系统。建立的生产线控制模型满足设置任务，这些任务在许多方面与由商业DCS系统执行。拟议的模型可以被其他设备有效替代安装在真实对象中。
提出的解决方案是软件与S7-1200控制器协作可防止为所有变量定义公共数据库。他们分别为每个控制器定义。实施控制系统的为比实施使用商业DCS的类似系统。此外，在建议的解决方案，可以自由选择可以独立的过程控制元件被改进的。综上所述，可以说，在设计分布式过程控制系统，PLC控制器可以使用，具有可用性和较低的是另一种解决方案。

n the case of PLC systems, PLC should not be included in the package, but competition with DCS suppliers forces PLC manufacturers to provide all other necessary software and packages. Many DCS designs allow cycle times to be configured for each function block. Therefore, the DCS system is responsible for the cycle time scheduling of function blocks as basic execution units.
This is one of the reasons why the overall scanning time of DCS is relatively higher than that of PLC system. This function has also been introduced into the PLC system in some form.DCS has inherent multiprocessor capability, so that functions are distributed in the network.In a typical multi processor (multi node) DCS architecture, engineers must make less effort to communicate with each other, or one controller can easily access tags from another controller&＃39;s database. That is, FB input to one controller can be the output of FB of another controller. Now this is possible in PLC, but more efforts must be made.
