AC20R4-A8PU | MITSUBISHI Programming unit cable AC20R4-A8PU


MITSUBISHI AC20R4-A8PU Product information and technical parameters:
Brand: MITSUBISHI
Name: Programming unit cable
Model: AC20R4-A8PU
CPU-A8UPU/A8PUJ connection.

8 slots.
To install the power supply.
For Q4AR power duplex.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order MITSUBISHI AC20R4-A8PU.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic AC20R4-A8PU
And the control principle is decentralized, centralized and hybrid control three.
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 AC20R4-A8PU.
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 MITSUBISHI AC20R4-A8PU.
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.
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.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of thhe electrical wiring diagram and wiring diagram AC20R4-A8PU.
Electrical interconnection diagram of each part of the design system.
According to the construction drawings of the site wiring, and carry out a detailed inspection.
Because the program deesign and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced AC20R4-A8PU.
