MITSUBISHI AJ71LP21 Product information and technical parameters:
Brand: MITSUBISHI
Name: SI/QSI fiber optic cable module
Model: AJ71LP21
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).
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.

Data communication line module (coaxial cable) Master / local station for A3VTS multiplex system.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures AJ71LP21.
Protection and chain is an indispensable part of the program, must be carefully considered AJ71LP21
It can avoid the control logic confusion caused by illegal operations. 16 channels.
Thermocouple input.
38 point terminal station.
Thermocouple I/P multiplex unit.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book AJ71LP21.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points AJ71LP21. Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:1.0.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: iit is a measure of how much the user application can store the number of indicators AJ71LP21.
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 llogical operation instructions each account for 1 words AJ71LP21. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
