REX521GHHG SH07G 综合保护继电器

PLC是一种用于工业生产自动控制的设备。一般来说，它可以直接在工业环境中使用，无需采取任何措施。

然而，尽管上述可靠性高、抗干扰能力强，但当生产环境太恶劣、电磁干扰特别强、或安装使用不当时，可能会导致程序错误或操作错误，导致误输入和误输出，从而导致设备失控和误操作，以确保PLC的正常运行。

为了提高PLC控制系统的可靠性，一方面要求PLC厂家提高设备的抗干扰能力；另一方面，需要高度重视设计、安装、使用和维护，多方合作可以提高问题的解决能力，有效提高系统的抗干扰性能。  

PLC is a kind of equipment used for automatic control of industrial production. In general, it can be used directly in industrial environments without taking any measures.

However, despite the above high reliability and strong anti-interference ability, when the production environment is too harsh, electromagnetic interference is particularly strong, or the installation and use is not appropriate, it may lead to program errors or operational errors, resulting in misinput and misoutput, resulting in equipment loss of control and misoperation to ensure the normal operation of the PLC.

In order to improve the reliability of PLC control system, on the one hand, PLC manufacturers are required to improve the anti-interference ability of equipment; On the other hand, it is necessary to attach great importance to design, installation, use and maintenance, and multi-party cooperation can improve the problem solving ability and effectively improve the anti-interference performance of the system.
