AD51-S3 Detailed analysis of the process and work characteristics of the controlled object, MITSUBISHI AD51-S3

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 the electrical wiring diagram and wiring diagram.
Electrical interconnection diagram of each part of the design system MITSUBISHI AD51-S3.
According to the construction drawings of the site wiring, and carry out a detailed inspection AD51-S3
Because the program design 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. 5 slots.
No need to install power.
For QnA/A series.
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 AD51-S3.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three MITSUBISHI AD51-S3.
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 MITSUBISHI Intelligent communication module.
A scan cycle is divided into the input sample, the program execution, the output refresh MITSUBISHI Intelligent communication module.
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 MITSUBISHI Intelligent communication modulle AD51-S3.
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 tto do the compiler to compile the process of interpretation MITSUBISHI AD51-S3.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
