Remote I/O controller, coaxial cable, coaxial loop system.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc A1SJ72QLR25 PDF. .
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps A1SJ72QLR25
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc A1SJ72QLR25 PDF. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Input and output points: 512 points.
Input / output data points: 512 points A1SJ72QLR25 PDF.
Program capacity: 8k.
Basic command processing speed (LD command) S:1.25.
RAM memory capacity: 32K, with computer connectivity.
The popularization and application of PLC programming has been developed rapidly in ouur country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment MITSUBISHI Reference Manual A1SJ72QLR25 Manual .
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students MITSUBISHI Reference Manual .
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Structured text language is a programming language that describes a program with a structured description of the text MITSUBISHI Reference Manual .
It is a programming language similar to a high level language. In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system.
Mainly used for other programming languages more diffficult to achieve the user program A1SJ72QLR25 Reference Manual .
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CCPU A1SJ72QLR25 Manual .
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
