FX Series PLC: FX3G PLC has a built-in large-capacity program memory, 32K steps, and the basic instruction processing speed can reach 0.21μs in specification mode. In the meantime, the FX series 5U is suitable for any industry, and is used by small and medium-sized enterprises. For example, this year's very popular mask machine is suitable for FX5U, and he can produce a more advanced mask N95.
Q series PLC: the program memory capacity can reach 252K steps, and the expansion memory can reach 32M, Q series PLC is generally used in large and medium-sized enterprises, because his system is huge.
L series: L series PLC is Mitsubishi's third generation of high-performance PLC, developed on the basis of Q series PLC.
A Series Mitsubishi PLC:
Mitsubishi PLCA series uses Mitsubishi's special sequential control chip (MSP), and the speed/instruction is comparable to that of large Mitsubishi PLC in the United States; A2ASCPU supports 32 PID circuits. The number of circuits in QnASCPU is unlimited, which can be changed with the size of the memory. The program capacity ranges from 8K steps to 124K steps, and the memory of QnASCPU can be expanded to 2M bytes if a memory card is used. There are a variety of special modules to choose from, including network, positioning control, high-speed counting, temperature control and other modules.
PLC series development:
1. Product planning is carried out in two directions: 14,336 I/O points, 32-bit microprocessor, multi-CPU parallel work, large-capacity memory, and high-speed scanning speed. Small: From the overall structure to the small modular structure, the flexibility of configuration is increased and the cost is reduced.
2. PLC is increasingly widely used in closed-loop process control.
3. Continuously strengthen the communication function.
4. New equipment and modules are constantly introduced In addition to the main selection of CPU to improve the processing speed, advanced PLC also has intelligent I/O modules with processors such as EPROM or RAM, high-speed counting modules, and remote I/O modules.
5. Programming things are rich and diverse, the functions are constantly improving, and the programming language tends to be standardized There are various simple or complex programmers and programming software, using ladder diagrams, utility diagrams, sentence lists and other programming languages, as well as advanced PLC instruction systems
6. Carry out fault-tolerant skills and choose hot standby or parallel work and majority voting methods.
7. Seek standardization of software and hardware.
PLC is widely used in agriculture, fishery, transportation, food industry, manufacturing industry, entertainment industry, medical care, environmental protection, energy and other industries! PLC is a new type of industrial automatic control equipment based on relay control, centered on microprocessor, integrating automatic control skills, computer skills and communication skills. At present, PLC has fundamentally replaced the traditional relay control system, and has become an important and widely used control equipment in the field of industrial automation, and is the first of the three pillars of industrial production automation (programmable manipulator, robot, computer-aided design and production).
