DCS系统配置
1. 系统配置的工作内容
DCS的发展使系统配置的适应性越来越强，而且也囊括了PLC控制功能，从几个、十几个回路的小系统到几百个、几千个回路的大系统都可以实现。系统配置的原则应是在满足装置生产和控制要求的前提下尽量减少硬件的数量，以求经济合理，并留有恰当的余量。系统配置工作主要包括以下几个方面。
（1） 系统I/O点统计：一般包括10-15%的备用量。要分别考虑热备用和冷备用的情况。
（2） 控制站：凡是参与控制的变量或重要的监视变量，考虑进入控制站。I/O卡件种类和数量按I/O点统计表的数量确定。机柜具有10%的备用空间。主控单元冗余配置、内部网络冗余配置、控制I/O卡冗余配置，电源冗余配置，按1秒的标准扫描周期估计系统负荷满足DCS具体要求，考虑现场变送器供电制式与DCS的关联。
（3） 监视站：对于有监视站的系统，可以考虑一些仅需要监视的点数到监控站中。但监视站一般不是冗余配置。
（4） 操作站：根据工艺流程工段或区域的划分和中控室内操作人员数确定操作站的台数。zui低限度要配两台带电脑设备的主操作站，打印机的台数应满足报警、报表及拷贝的需要，但报警和报表用的打印机必须分开。
（5） 辅助操作台的配置：安装闪光报警器、指示仪、手操器、开关按钮、指示灯、端子排、空开、等。
（6） 其他站或模件的配置：根据不同系统的结构及功能需要，可配置工程师站、大屏幕、上位机等。
（7） 通信系统配置：凡是与通信有关的网卡、网线（总线）、交换机、耦合器、调制解调器等应根据需要考虑冗余配置。
（8） 系统电源和辅助机柜配置（安全栅柜、端子柜、继电器柜、配电箱等）：UPS不间断电源容量比DCS系统所需容量高40%，并保证电网停电时能继续供电30分钟。按现场危险场所划分，*安全栅型号。
（9） 备品备件和消耗品，原则上要备足两年的用量、
