MELSECNET/10 Network System AJ72LR25 Reference Manual MITSUBISHI AJ72LR25 Manual

Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 0.2ms the following.
Rated input voltage / current: DC24V/5mA.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup AJ72LR25 Reference Manual .
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool AJ72LR25 SI/QSI/H-PCF/ wide range H-PCF fiber optic cable.
Double loop.
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 AJ72LR25 Reference Manual . .
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 AJ72LR25 Reference Manual . .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram MITSUBISHI AJ72LR25 Manual .
So far the system''s hardware electrical circuit has been determined. 10BASE2.
Q mode.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian MITSUBISHI AJ72LR25 Manual .
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 AJ72LR25 Manual .
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. Output points: 16 points.
Voltage: DC5/12V.
Output type: Sink type.
Response time: 1ms.
8 points / a common end.
20 point terminal station.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requiremeents,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ72LR25 .
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation AJ72LR25 Reference Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
