Plc features and functions
(1) The main characteristics of plc. The characteristics of plc are: reliable work, fast running speed, building block structure, flexible combination, good compatibility, simple and rich programming and generation, strong network function.
(2) The main functions of plc. Plc system can well complete industrial real-time sequence control, state control, counting control, step control and other functions; It can complete analog/digital (a/d), digital/analog (d/a) conversion, data processing, communication networking, real-time monitoring and other functions. Years of practice has shown that plc is reliable, specially designed for the factory, with reinforced components according to the requirements of the working environment, real-time scanning practice and fault diagnosis functions, and simple troubleshooting, which is favored by users. The reason why plc is so reliable is that it is a real-time core or operating system, which can execute relay logic, sequence function diagram, function block, structure text, command directory or their combination. In case of failure, its built-in equipment can maintain mechanical damage, and can maintain an orderly and predictable sequence.
We know that reliability is very important for industrial production. Every producer hopes that his production line will always maintain a good production condition, but the reality tells us that this is impossible. We can try our best to avoid equipment problems and reduce the possibility of problems. At this time, the PLC control system is much better than the original relay control. In fact, we can see this from the appearance of both sides. After all, there are more lines in the relay control system, and the installation and removal are more complicated. Many lines are densely interwoven, which is not only easy to damage the line due to mutual friction, but also easy to interfere with the signal electromagnetic wave in the opposite line. PLC equipment is relatively simple and rule-based, and is not easy to be damaged by self interference.

PLC is a device used for automatic control in industrial production. Generally speaking, it can be used directly in industrial environments without taking any measures. However, despite the high reliability and strong anti-interference ability mentioned above, when the production environment is too harsh, electromagnetic interference is particularly strong, or installation and use is not appropriate, it may lead to program errors or operational errors, resulting in incorrect input and output, leading to equipment loss of control and misoperation, to ensure the normal operation of the PLC. In order to improve the reliability of PLC control systems, on the one hand, PLC manufacturers are required to improve the anti-interference ability of the equipment; On the other hand, it is necessary to attach great importance to design, installation, use, and maintenance. Multi party cooperation can improve the problem-solving ability and effectively improve the anti-interference performance of the system.
