MITSUBISHI AJ71QLP21S Product information and technical parameters:
Brand: MITSUBISHI
Name: SI/QSI fiber optic cable module
Model: AJ71QLP21S
SI/QSI/H-PCF/ wide range H-PCF fiber optic cable.
Double loop.
PC inter network (management station / station) / remote I/O network (remote control station).
External power supply function.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
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.
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..
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.

Adapter for mounting rails. Unit connection CPU unit.Cable for extended use in multiplexing unit.Ethernet network module 10BASE5/10BASE2
Control layer /MELSECNET/10 (H) is the middle layer of the whole network system,
Control network which is convenient and high speed processing data transmission between PLC, CNC and other control equipment AJ71QLP21S.
As MELSEC control network MELSECNET/10,
With its good real-time performance, simple network settings, no procedures of the network data sharing concept,
As well as the redundant circuit and so on, has obtained the very high market appraisal,
The number of devices to reach the highest in japan,
In the world is also one of the few AJ71QLP21S
And MELSECNET/H not only inherited the excellent characteristics of MELSECNET/10,
Also makes the network real-time better, more data capacity,
Further adapt to the needs of the market AJ71QLP21S. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function.
AnNCPU command processing time and ACPU compare to 10-20% high speed processing AJ71QLP21S.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Program 1 channel connection, AnCPU/QnACPU use.
MITSUBISHI PLCC detection, fault diagnosis and display and other procedures AJ71QLP21S.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures.
Protection aand chain is an indispensable part of the program, must be carefully considered AJ71QLP21S.
It can avoid the control logic confusion caused by illegal operations.
