在设计阶段要严格计算和规范DCS控制器工作负荷，还要仔细核算通讯网络负荷，在设计变更时，要考虑到I/O点的冗余以及报警数量等。同时在正式运行该系统前要进行调试和试运行，模拟可能会发生的各种紧急情况，及时发现其存在的通讯故障，防止运行后造成不必要的经济损失。
06 建立科学合理的DCS维护管理系统
DCS维护人员应每天按时检查DCS机柜和通信网络各模块的工作状态，检查是否发生故障提示，并及时分析产生异常情况的原因，并且及时进行处理。用网络测试仪检查网络的硬件工作状态，以及检查交换机的指示灯，使用“ping”命令检查计算机网络，以及每台计算机的IP设置。在检查卡件以及通讯部件时，要佩戴防静电手腕，防止静电导致通讯故障。In the design stage, the working load of DCS controller shall be strictly calculated and standardized, and the communication network load shall be carefully calculated. In the design change, the redundancy of I / O points and the number of alarms shall be considered. At the same time, before the formal operation of the system, commissioning and trial operation shall be carried out to simulate various emergencies that may occur, and the existing communication faults shall be found in time to prevent unnecessary economic losses after operation.
06 establish a scientific and reasonable DCS maintenance management system
DCS maintenance personnel shall check the working status of DCS cabinet and communication network modules on time every day, check whether there is fault prompt, timely analyze the causes of abnormal conditions and deal with them in time. Use the network tester to check the hardware working status of the network and the indicator light of the switch. Use the "Ping" command to check the computer network and the IP setting of each computer. When checking cards and communication components, wear anti-static wrist to prevent communication failure caused by static electricity.
