The performance characteristics of Delta PLC

< p="">

Delta PLC is known for its fast speed, robustness and high reliability, and is widely used in various industrial automation machines. In addition to the features of fast program calculation, rich instruction set, multi-expansion function card and high performance price ratio, Delta PLC also supports multiple communication protocols to integrate industrial automation systems. In order to adapt to the industrial environment, PLC has the following characteristics compared with general control devices: 1. High reliability and strong anti-interference ability. The two main measures of hardware and software ensure the reliability of the control device:
Hardware measures: The main modules are large-scale or very large-scale integrated circuits. A large number of switching actions are done through a contactless electronic memory. The I/O system has complete channel protection and signal conditioning circuitry. Software measures: powerful self-testing and protection. 2, strong versatility, variable program, easy to use. The PLC has a full range of hardware devices that can form a control system that meets various requirements. Users do not have to design and manufacture hardware devices themselves. After the hardware is determined, in the case of changes in the production process or production equipment update, the user does not need to replace the hardware equipment of the PLC, and only needs to adjust the scheme to meet the requirements. 3, strong function and wide adaptability. Modern PLC not only has functions such as logic operation, timing, counting, and timing control. It also has digital-to-analog input and output, power drive, communication, man-machine dialogue, self-test, record display and other functions. It can control a production machine, a production line, and control a production process. 4, programming is simple, easy to master. Most PLCs still use the "trapezoidal programming method" in the form of relay control. It not only inherits the clarity and intuitiveness of the traditional control circuit, but also considers the reading habits and programming level of the electrical technicians of most factory enterprises, which is easy to be accepted and mastered. 5. Reduce the design and construction workload of the control system. Since the PLC uses software to replace a large number of intermediate relays, time relays, counters, etc. in the relay control system, the design and installation wiring of the control cabinet is greatly reduced. At the same time, the PLC user program can perform simulation debugging in the laboratory, reducing the amount of on-site debugging work. In addition, due to the low PLC failure rate, strong monitoring function, modularity, etc., maintenance is also very convenient. 6. Small size, light weight, low power consumption and convenient maintenance. A programmable controller (PLC) is applied to industrial equipment using microelectronics technology. Compact, rugged, small, lightweight and low power consumption. Because PLC has strong anti-interference ability, it is easy to install inside the equipment, and it is an ideal control equipment for mechatronics.
