MITSUBISHI AJ72LP25G How to choose MITSUBISHI PLCMITSUBISHI AJ72LP25G
Output points: 32 points.
Voltage: DC5/12/24V.
OFF leakage current: 0.1mA.
Output type: bidirectional thyristor output (type sink).
Response time: 10ms.
8 points / a common end.
50 point terminal station.
With the surge absorber.
Each scanning process. Focus on the input signal sampling AJ72LP25G. Focus on the output signal to refresh.
Program in the implementation phase, the input end of a new state, the new state can not be read AJ72LP25G.
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 AJ72LP25G.
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 MITSUBISHI AJ72LP25G.
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 MITSUBISHI AJ72LP25G. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 AJ72LP25G.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Enter 16 points.
Voltage and current: 14mA DC24V.
Response time: 8ms.
16 point 1 public end, 20 point terminal.
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.
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.
Remote I/O controller, optical fiber GI.
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 AJ72LP25G..
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.
