DCS系统故障诊断步骤
　　DCS系统一旦出现故障，正确分析和诊断故障发生的部位是当务之急。故障的诊断就是根据经验，参照发生故障的环境和现象，来确定故障的部位和原因。这种诊断方法因DCS系统产品不同而有一定差别。
　　1)是否为使用不当引起的故障。这类故障常见的有供电电源错误、端子接线错误、模板安装错误、现场操作错误等。
　　2)是否为DCS系统操作错误引起的故障。这类故障常见的有某整定参数整定错误、某设定状态错误造成的。
　　3)确认是现场仪表设备故障还是DCS系统故障。若是现场一次仪表故障，修复相应现场仪表。
　　4)若是DCS系统本身的故障，应确认是硬件毛病或是软件故障。
　　5)若是硬件故障，找出相应的硬件部位，更换模板。　6)若是软件故障，还应确认是系统软件或是应用软件故障。
　　7)若是系统软件有故障，可重新启动看能否恢复，或重新装载系统软件重新启动。
　　8)若是应用软件故障，可检查用户编写的程序和组态的所有数据，找出故障原因。
　　9)利用DCS系统的自诊断测试功能，DCS系统的各部分都设计有相应的自诊断功能，在系统发生故障时一定要充分利用这一功能，来分析和判断故障的部位和原因。
