[Abstract] PLC (PLC) in industrial control applications in the increasingly broad and PLC control system directly affects the reliability of the industrial enterprises in production safety and economic operation, the PLC in the application of the need to improve their systems Anti-interference capability. According to the author of this article for many years the design, installation and use of experience, proposed the use of attention in a number of issues, to draw the attention of users.
Overview
With the development of science and technology, PLC in industrial control of more and more extensive. PLC control system directly affects the reliability of the industrial enterprises in production safety and economic operation, the system's anti-interference capability is related to the whole system reliable operation of the key. Automation systems used in various types of PLC, some focus on the installation in the control room For example, I plant sewage oxidation ditch field operations room of the PLC , some are installed in production at the scene and electrical equipment (such as the two catalysts automatically sootblowers And instrumentation control after large-scale use of the PLC), most of them are strong, strong, equipment and circuit formed by the poor in the electromagnetic environment. PLC control system to improve reliability, ask the PLC equipment manufacturers improve the anti-jamming capabilities on the other hand, require engineering design, construction and installation of the use of maintenance attach great importance to multi-perfect solution to meet, effectively enhance system The anti-jamming performance.
