故障维护
系统使用者自身进行的日常维护,维护人员应对系统维护技术难度和可操作性有一定的认识,了解应具备的维护工具,明确哪些工作能自己完成,做到心中 有数,出现问题要及时制定可行的维护方案。对DCS系统故障维护的关键是快速、准确地判断出故障点的位置，故障维护中的一些经验总结如下下几点：
1） DCS系统往往具有丰富的自诊断功能。根据报警,可以直接找到故障点,并且还可通过报警的消除来验证维修结果。
2） 通信接头接触不良会引起通信故障,确认通信接头接触不良后,可以利用工具重做接头;通信线破损应及时更换。
3） 某个卡件故障灯闪烁或者卡件上全部数据都为零,可能的原因是组态信息有错、卡件处于备用状态而冗余端子连接线未接、卡件本身故障、该槽位没有组态信息等。
4） 当某一生产状态异常或报警时,我们可以先找到反映此状态的仪表,然后顺着信号向上传递的方向,用仪器逐一检查信号的正误,直到查出故障所在。
5） 当出现较大规模的硬件故障时，最大的可能是由于DCS系统环境维护不力而造成的系统运故障，除当时采取紧急备件更换和系统清扫工作外，还要及时和厂家取得联系，由厂家专业技术支持工程师进一步确认和排除故障

预防维护

有计划地进行主动性、预防性维护,保证系统运行稳定可靠。根据大修周期，利用大修进行一次预防性的维护，以掌握系统运行状态,消除故障隐患。大修期间对DCS 系统应进行彻底、全面的维护，内容包括：

1） 系统冗余测试: 对冗余电源、服务器、控制器、通讯网络进行冗余测试。操作站、控制站停电检修。包括计算机内部、控制站机笼、电源箱等部件的灰尘清理。

2） 系统供电线路检修。并对UPS进行供电能力测试和实施放电操作。

3） 接地系统检修。包括端子检查、对接地电阻测试。

大修后系统维护负责人应确认条件具备方可上电，并应严格遵照上电步骤进行。
