Is it better to learn Siemens or Mitsubishi

Mitsubishi PLC is a Japanese brand, and the programming is intuitive and easy to understand, which will be easier to learn, but there are many instructions. Siemens PLC is a German brand, the instructions are more abstract, the learning is more difficult, but the instructions are less, so the cycle of learning Mitsubishi and learning Siemens is the same.

The main difference between Siemens PLC and Mitsubishi PLC is that Siemens has always advocated the use of structured programming, that is, the program of a device is composed of several subprograms, each subprogram is responsible for a function, and then called through the main program when needed, which has many benefits, such as finding faults, debugging, etc. are very convenient, and all of Mitsubishi's programs are in a main program (at least the FX series), if the program is longer, it is very troublesome to debug, and there is in terms of analog processing, Siemens is also more convenient than Mitsubishi's.

Therefore, it is recommended to learn from Siemens.

Learn PLC first learn Mitsubishi or Siemens is introduced as follows:

Learn PLC, Mitsubishi is easier to get started, because Mitsubishi is Japanese, programming is intuitive and easy to understand, the idea is simple, it will be easier to learn, but there are more instructions, it is recommended to learn Mitsubishi's FX series first. But from the perspective of learning and prospects, Siemens is better, if you want to learn Siemens, it is recommended to learn S7-200 first, although 200PLC has been discontinued, but it is relatively simple, after all, it is a Siemens product, there will not be much difference, first easy and then difficult, step by step is the truth.

PLC (Programmable Logic Controller) generally refers to a programmable logic controller (programmable control device).

A programmable logic controller is an electronic system designed for digital operations in industrial environments. It uses a programmable memory to store instructions for performing operations such as logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs.

Introduction: <>

Programmable logic controller (PLC), a digital computing controller with a microprocessor for automatic control, can load control instructions into memory at any time for storage and execution. The programmable controller is composed of CPU, instruction and data memory, input and output interfaces, power supply, digital and analog conversion and other functional units. The early programmable logic controller only had the function of logic control, so it was named the programmable logic controller.

Later, with the continuous development, these computer modules with simple functions have included logic control, timing control, analog control, multi-machine communication and other functions, and the name has also been changed to programmable controller (programmable controller), but because of its abbreviation PC and personal computer (personal computer) abbreviation conflict, coupled with the habitual reasons for cracking, people still often use the name programmable logic controller, The abbreviation PLC is still used.

The programmable logic controller used in industry has been equivalent to or close to the host of a compact computer, and its advantages in scalability and reliability make it widely used in various industrial control fields.

Whether it is in the computer direct control system, the centralized decentralized control system DCS, or the fieldbus control system FCS, there are always a large number of PLC controllers of all kinds. There are many PLC manufacturers, such as Siemens, Schneider, Mitsubishi, Delta, etc., and almost all manufacturers involved in the field of industrial automation will have their PLC products to provide.

This is all good, and it is better to learn both. Siemens PLC is a European PLC that pays more attention to data and has strict requirements for data types. Mitsubishi PLC is a Japanese PLC that pays more attention to function, and there are relatively many functional instructions.

The current PLC is either more similar to Siemens or more similar to Mitsubishi. Therefore, it is best to learn both, so that it will be much easier to contact the PLC of other manufacturers in the future.

Hope...

Mitsubishi belongs to the Japanese system, and Siemens belongs to the European system, each with its own characteristics. In practical applications, you can learn which one you use more, and which one you learn well, and other PLCs are the same.

I want to learn PL and I am bored, and Mitsubishi is so entangled. I think Mitsubishi is the best, Mitsubishi refrigerator, really good.

Their programming concepts are different, Mitsubishi PLC is a Japanese brand, programming is intuitive and easy to understand, and it will be easier to learn, while Siemens PLC is a German brand, the instructions are more abstract, and it is more difficult to learn, but there are fewer instructions, while Mitsubishi has more instructions, so the cycle of learning Mitsubishi and learning Siemens is the same; Mitsubishi's advantage lies in discrete control and motion control, Mitsubishi's instructions are abundant, there are special positioning instructions, control servo and stepping are easy to implement, to achieve some complex action control is also Mitsubishi's strength, and Siemens is weaker in this area, there is no special instruction, do servo or step positioning control is not unrealizable, but the program is complex, and the control accuracy is not high. Process control and communication control Siemens is a strong point, Siemens' analog module is cheap and the program is simple, while Mitsubishi's analog module is expensive and the program is complex, Siemens is also easy to communicate, the program is simple, and Mitsubishi is weak in this function. Therefore, for different equipment and different control methods, we must reasonably choose PLC, use its advantages and avoid its shortcomings.

For example, a certain equipment is only some action control, such as a manipulator, you can choose Mitsubishi's PLC, a device has a servo or stepping to control the positioning, also choose Mitsubishi's PLC; Like ** air conditioning, sewage treatment, temperature control, etc., there are many analog quantities to be processed, it is more appropriate to choose Siemens' PLC, and there are many instrument data to be collected by communication on the site of a certain equipment, and Siemens' good control is chosen. To learn to choose a certain brand, we should combine it with the actual situation to see whether it should be used more widely in various industries, small enterprises, Japanese-funded enterprises, and Taiwan-funded enterprises Mitsubishi; Large enterprises and the north are used more by Siemens. And it is also very important to choose a good PLC training institution!

Everyday Automation PLC Training Institution: Your first choice for PLC training!

1. Mitsubishi PLC's FX series has stable and reliable performance, good performance and high cost performance. But it is inconvenient to use expansion modules, which is a big weakness of Mitsubishi;

2. Siemens' advantage is that large and medium-sized PLCs do relatively well, which Mitsubishi will never be able to match; However, the stability of Siemens' small PLC is not as good as that of Mitsubishi, but Siemens' small PLC is much more convenient to use than Mitsubishi.

The main difference is the appearance of the PLC, the number of points it carries, and the difference in function.

There is no big difference, it is nothing more than some, the difference in instructions.

Mitsubishi is Japanese, Siemens is German. In addition to the difference in appearance and development platform, Siemens is more powerful, of course, it is also higher, and its market share is also larger. In terms of the friendliness of the development platform, Siemens is also far superior to Mitsubishi.

Differences between the programming methods of Siemens and Mitsubishi PLC: Siemens tends to be more structured programming, while Mitsubishi is usually linear or modular programming.

1. Understand the working mode of PLC.

2. Proficient in PLC programming instructions and applications.

3. Find some materials with examples, write programs according to the logic of examples, and practice a lot until you are proficient in applying various instructions and program structures, programming methods and methods.

4. Compile comprehensive example programs, summarize them, and think about the rules of PLC programming

5. Plan or actually participate in a control project, write design specifications, flow charts, etc., and provide your own comprehensive ability.

6. Learning--> application--> learning--> application, a virtuous cycle of learning.

See more, think more, do more, the main thing is to have a use environment, it is recommended that you find a design department of a company that does related applications, and then learn it quickly, and it is also a good way to go to the ultraviolet industrial control network to communicate with other netizens.

Having an experimental environment is the most important thing! This thing is very poor just by reading a book, and it will be quite quick to learn it with actual equipment.
