Reliability is the key performance of electrical control equipment. Due to the use of modern large-scale integrated circuit technology, strict production processes, and advanced anti-interference technology for internal circuits, PLC has high reliability. For example, the F series PLC produced by Mitsubishi has an average time between failures of up to 300000 hours. Some PLCs that use redundant CPUs have longer mean time between failures.
Using PLC to form a control system, compared to relay contactor systems of the same scale, the electrical wiring and switch contacts have been reduced to hundreds or even thousands of times, greatly reducing faults. In addition, the PLC has a hardware fault self detection function, which can send out alarm messages in a timely manner when a fault occurs. In the application software, the application can also program fault self-diagnosis programs for peripheral devices, enabling circuits and equipment in the system other than PLC to also receive fault self-diagnosis protection. In this way, it is not surprising that the entire system has extremely high reliability.
PLC has developed to this day, forming a series of products of various scales, including large, medium, and small. It can be used in various scale industrial control occasions. In addition to logical processing functions, most modern PLCs have comprehensive data processing capabilities and can be used in various digital control fields. In recent years, a large number of functional units of PLC have emerged, allowing PLC to penetrate various industrial controls such as position control, temperature control, CNC, etc. With the enhancement of PLC communication capabilities and the development of human-machine interface technology, it has become very easy to use PLC to form various control systems.
