Anonymous users2024-02-06The letters of Mitsubishi PLC are some instructions with mnemonics.
For example, X is the input relay, Y is the output relay, T is the timer, C is the counter, and so on.
And mnemonics refer to mov, add, out, ld, ldi, etc.
MOV is a transfer instruction that is used to transfer the value of a register to another register.
Add is an addition instruction, such as [addd0k8d0], after the instruction is completed, the value of d0 and the value of k8 are added and placed in d0.
out is the output command, and the user outputs the power of the relay.
ld is a fetch instruction that is used to get the current input state.
LDI is a negation instruction that is used to obtain the input state of the current inverse.

Anonymous users2024-02-05Dear, we are glad to answer for you: What is the coincidence of Siemens PLC and Mitsubishi PLC input and output substitution? A:
Dear, hello, the commonly used PLC input symbols are X and I, the input symbol represented by Mitsubishi PLC is represented by X, and the input symbol represented by Siemens PLC is represented by I. The X on the PLC represents the input terminal, and the Y represents the output terminal, such as the PLC of the Mitsubishi series, I represents the input terminal of the judgment terminal, and the Q represents the output terminal, such as the PLC of the Siemens series, AI stands for analog input, and AQ stands for analog output. The X on the PLC represents the input terminal, and the Y represents the output terminal, such as the PLC of the Mitsubishi series, the I represents the input terminal, and the Q represents the output terminal, such as the PLC of the Siemens series, AI stands for analog input, and AQ stands for analog output.

Founded in 1847, Siemens AG is a global leader in electrical and electronic engineering. In 2014, Siemens sold its stake in BSH and completely withdrew from the home appliance sector to focus on electrification, automation and digitalization.
Our Digital Enterprise solutions cover industrial software, industrial communication, industrial security, and data-based services.
Siemens' main products include programmable logic controllers (PLCs), industrial computers (IPCs) and industrial operation panels (HMIs), industrial software, CNC machine tools, low-voltage electrical appliances, touch screens, etc.
Siemens is synonymous with "Made in Germany", and it is also a model for many Chinese manufacturing enterprises to learn.
7. Mitsubishi Electric Co., Ltd. ****.
As a global company, Mitsubishi Electric has been committed to the research, development and manufacturing of cutting-edge technologies and expertise for more than 90 years.
Mitsubishi is mainly engaged in information and communication systems, electronic components, heavy electrical systems, industrial automation systems, automotive electrical equipment and household appliances, and is a world leader in satellites, defense systems, ventilation equipment, and other fields.
In addition, Mitsubishi Electric has excellent display equipment and display device technology.
In recent years, Mitsubishi Electric has established more than 30 joint ventures and wholly-owned enterprises in China, and they are actively engaged in various businesses and technology transfer in a wide range of fields such as electronic devices such as automotive parts and semiconductors, as well as electronics and machines such as power transmission and transformation equipment, elevators, electric products for railway vehicles, industrial automation equipment, and household appliances.

Anonymous users2024-02-03Programmable controllers are produced by the needs of modern production, and are sub-programmable controllers.
Siemens PLCS7-200 series.
The class must also meet the needs of modern production.
In general, programmable controllers can be classified from three perspectives. The first is to classify from the control scale of the programmable controller, the second is to classify from the performance of the programmable controller, and the third is to classify from the structural characteristics of the programmable controller.
Control scale. It can be divided into large-scale, medium-sized and small-sized machines.
Siemens PLCS7-300 series.
Minicomputer: The control point of the minicomputer is generally within 256 points, which is suitable for single machine control or small system control.
Siemens miniature machine has S7-200: processing speed; Memory 2k; 248 digital amounts; Analog 35 channels.
Medium-sized machine: The control point of medium-sized machine is generally not more than 2048 points, which can be used for direct control of equipment, and can also monitor a number of programmable controllers at the next level, which is suitable for the control of medium-sized or large-scale control systems.
Siemens medium-sized machine has S7-300: processing speed; Memory 2k; 1024 digital points; Analog 128 channels; network profibus; Industrial Ethernet; mpi。
Mainframe: The control point of the mainframe is generally greater than 2048 points, which can not only complete more complex arithmetic operations.
Siemens PLCS7-400 series.
Complex matrix operations can also be performed. It can be used not only for direct control of the device, but also for the monitoring of multiple subordinate programmable controllers.
Siemens mainframe has S7-400: processing speed 1K words;
Memory 512k ; point 12672;

Anonymous users2024-02-02Siemens PLC has the following series:
S7-200CN, S7-200, S7-300, S7-400, ET200, S7-1200 series, each series of models are particularly many, imported things have very strict requirements for models, a number or a letter wrong is something else.
The model format is:
Mitsubishi PLC FX1S-10MT-001
Mitsubishi PLC FX1N-24MR-001
Mitsubishi PLC FX2N-32MR-001
Mitsubishi PLC FX2N-64MR-001
Mitsubishi PLC FX2N-128MR-001
Mitsubishi PLC FX2N-80MR-001
Mitsubishi PLC FX1S-30MT-001
These two are mainstream PLCs, one made in Japan, one made in Germany, I have used both, both are very representative, it is recommended to learn both, you can learn Mitsubishi's first, because most of the programming methods of other brands of PLC are imitation of Mitsubishi, especially domestic brands, just like the Delta I use now, and Xinjie, which is almost exactly the same as Mitsubishi. Mitsubishi is what a traditional ladder looks like. And Siemens is also unique, although he also said that it is a ladder diagram, but his is a modular ladder diagram, which looks more intuitive than Mitsubishi's, and the step7 software is also very easy to use. >>>More
The problem you encounter now is something I have experienced when I used to study on my own, I used to buy a ** of technical success, I can only read it for a year, and I bought a lot of books, and I look at it Sometimes I doze off, sometimes I encounter a problem, although I have a friend who is an engineer and can occasionally answer it, but it is not good to trouble people often, and then I don't want to learn when I learn to learn, and there was no equipment practice at that time, and I didn't learn again for several months, and then it was a colleague of mine, who used to be an electrician together, He learned from Bojun PLC, at that time his monthly salary was more than nine k, and then I also went to study, and now I am also an engineer, and I also take on some projects in my spare time, which is not bad.
Mitsubishi PLC programming program how to write PLC Hello, 1, after the program is written, you need to transform the program first, there are three ways to transform: the first is to press the F4 key of the keyboard directly, the second is to click the "transform" menu bar, and then click the first item "transform", the third is to click the "program transform" button of the toolbar, we choose the appropriate transformation method according to their own habits 2, after the program is transformed, you need to check whether there are syntax errors in the program, This check only self-diagnoses the syntax, not the design content. To check the program, click "Program Check" in the menu bar of the tool. >>>More
Explanation: Two devices of the same model may have different programs. The same MMC card model only means that the hardware is the same, but the user program is not necessarily the same. >>>More
Siemens PLC transmission instructions are mainly divided into two categories, one is single transmission, and the other is block transmission >>>More
