5、执行机构可靠性研究
当现场的信号准确地输入给PLC后，PLC执行程序，将结果通过执行机构对现场装置进行调节、控制。怎样保证执行机构按控制要求工作，当执行机构没有按要求工作，怎样发现故障？我们采取以下措施：当负载由接触器控制时，启动或停止这类负载转为对接触器线圈控制，启动时接触器是否可靠吸合，停止时接触器是否可靠释放，这是我们关心的。
X0为接触器动作条件，Y0为控制线圈输出，X1为引回到PLC输入端的接触器辅助常开触点，定时器定时时间大于接触器动作时间。R0为设定的故障位，R0为ON表示有故障，做报警处理；R0为OFF表示无故障。故障具有记忆功能，由故障复位按钮清除。
当开启或关闭电动阀门时，根据阀门开启、关闭时间不同，设置延时时间，经过延时检测开到位或关到位信号，如果这些信号不能按时准确返回给PLC，说明阀可能有故障，做阀故障报警处理。程序设计如图3b 所示。X2为阀门开启条件，Y1为控制阀动作输出，定时器定时时间大于阀开启到位时间，X3为阀到位返回信号，R1为阀故障位。
6、结论
我们在胜利油田胜利采油厂胜砣注聚站自动控制系统设计中采用了以上方法，经过近2年的运行证明这些方法的采用对提高系统可靠性运行是行之有效的。
