According to statistics, CPU accounts for 5%, I/O interface accounts for 15%, input equipment accounts for 45%, output equipment accounts for 30%, and lines account for 5% of PLC control system failures. A total of 20% of the faults in the first two items belong to the internal faults of PLC, which can be detected and handled through the software and hardware of PLC itself; The remaining 80% of the faults are external faults of PLC. Therefore, PLC manufacturers are committed to developing and developing special intelligent modules for detecting external faults to further improve the reliability of the system.

Programming language diversification

With the continuous development of PLC system structure, PLC programming language is becoming more and more rich, and its functions are also constantly improved. In addition to the ladder diagram language used by most PLCs, in order to adapt to various control requirements, step programming language for sequence control, flow chart language for process control, high-level language compatible with computers (BASIC, C language, etc.) have emerged. The coexistence, complementation and development of multiple programming languages is a trend of PLC progress.
