Modern PLC not only has the functions of logic operation, timing, counting, sequence control, but also has the functions of digital and analog input and output, power drive, communication, human-computer dialogue, self-inspection, record display, etc. It can control a production machine, a production line and a production process.

Simple programming, easy to master

At present, most PLCs still use “ladder diagram programming mode” in the form of relay control. It not only inherits the clarity and intuition of the traditional control circuit, but also takes into account the drawing reading habits and programming level of the electrical technicians in most factories and enterprises, so it is very easy to accept and master. The symbols and expressions of programming elements in ladder diagram language are quite close to the schematic diagram of relay control circuit. Through reading the user manual of PLC or short-term training, electrical technicians and technicians can quickly learn to use ladder diagram to compile control programs. At the same time, it also provides programming languages such as function diagram and statement table.

When the PLC executes the ladder program, it uses the interpreter to translate it into assembly language and then executes it (the interpreter is added inside the PLC). Compared with the user program written directly in assembly language, the execution time of ladder program is longer, but for most electromechanical control equipment, it is insignificant and can completely meet the control requirements.

Reduce the workload of control system design and construction

Because PLC uses software to replace a large number of intermediate relays, time relays, counters and other devices in the relay control system, the design, installation and wiring workload of the control cabinet is greatly reduced. At the same time, the user program of PLC can be simulated and debugged in the laboratory, which further reduces the on-site debugging workload. Moreover, due to the low failure rate, strong monitoring function and modularization of PLC, the maintenance is also very convenient.
