浅谈PLC的试运行与后期维护

Test Run and Post-Maintenance of the PLC

可编程控制器（PLC）由于具有可靠性高、功能强大、使用方便、维护相对简单等显著特点，已广泛应用于工业控制的各个领域。为了使PLC连续工作在最佳状态，在PLC正式使用前要进行试运行，此外使用后期的周期性检查、维护也是非常重要的。本文对PLC的试运行与后期维护进行了探讨。

Programmable Logic Controller（PLC）as high reliability,powerful,easy to use,maintenance is relatively simple and so striking feature has been widely used in industrial control fields.For continuous work in the best PLC,the PLC prior to use to conduct a formal test run, in addition to the periodic use of post-inspection,maintenance is also very important.In this paper, the PLC and post-maintenance test run was discussed.
