3C-2V/5C-2V coaxial cable between the single bus PC network (control station / common station) / remote I/O network (remote master).
Q mode.
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
And then output to the output interface, control the external drive.
Semiconductor circuit with memory function.
System program memory and user memory.
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
User memory: user program storage area and work data storage area.
Composed of random access memory (RAM). User use.

Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions MITSUBISHI A1SJ71QBR11
A1SJ71QBR11
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time MITSUBISHI A1SJ71QBR11.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in accordance with the functional flow of the order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the complicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced MITSUBISHI A1SJ71QBR11 MITSUBISHI Network module. 5 slots.
Installation of the power unit can not be used for AnS QnAS/ series units installed MITSUBISHI Network module.
The popularization and application of PLC programming has been developed rapidly in our 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 Network module.
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.
PLC user program is designed accordinng to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design A1SJ71QBR11.
As long as the user caan master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions MITSUBISHI A1SJ71QBR11.
