A0J2CPU MITSUBISHI A0J2CPU Basic command processing speed: 44 ~ 56us 

Brand: MITSUBISHI
Name: CPU unit
Model: A0J2CPU
Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input AC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
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.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.

Input points: 32 points.
Voltage: DC12/24V.
Current: 3/7mA.
Response time: 10ms.
16 points / a common end.
Positive pole sharing.
36 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 MITSUBISHI A0J2CPU A0J2CPU
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 MITSUBISHI A0J2CPU.
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 MITSUBISHI A0J2CPU.
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 requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI CPU unit.
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 CPU unit.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. 16 channels.
Input: DC-10 ~ 10V, DC-20 ~ 20mA MITSUBISHI CPU unit.
38 point terminal station.
Analog quantity I/P multiplexing unit (isolation channel).
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 A0J2CPU.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devicees 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 MITSUBISHI A0J2CPU.
