A1SJ71QLP21 MITSUBISHI A1SJ71QLP21 Network module

Brand: MITSUBISHI
Name: Network module
Model: A1SJ71QLP21
SI/QSI/H-PCF/ wide H-PCF optical cable double loop PC (control station / common station) / remote I/O network (remote master station).
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect.

I/O slots: 5 slots.
Can you install the power module.
Outline dimension: 260*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate MITSUBISHI A1SJ71QLP21.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board A1SJ71QLP21
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. RS-232 2 channel.
Transfer speed: 2 channels.
A total of 115.2kbps.
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 MITSUBISHI A1SJ71QLP21.
And then combine the data and the program with CPU.
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.
Semiconductor circuit with memory function.
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation MITSUBISHI A1SJ71QLP21.
Read only memory. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI Network module. 10BASE2.
Q mode.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI Network module.
When the programmer input programinto the user program memory,
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 MITSUBISHI Network module. 5 slots.
Can be installed in the power supply unit for AnS series units installed QnAS/.
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.
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 A1SJ71QLP21.
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 A1SJ71QLP21.
