Providing high speed communication between multiple CPU.
Shorten the fixed scan interrupt time, high precision device MITSUBISHI PLC Programming Manual.
The minimum interval of the fixed period interrupt program is reduced to 100 s Q173DCPU
The high speed signal can be accurately obtained, which makes the contribution to the higher precision of the device.
High speed and high precision machine control by multi CPU.
By parallel processing of the linear and multi CPU high-speed communication (cycle 0.88ms) of the parallel control program, the high speed control MITSUBISHI PLC Programming Manual.
Multi CPU high speed communication cycle and motion control synchronization, so it can achieve the maximization of computing efficiency.
In addition, the latest movement control CPU in performance is 2 times the previous model,
To ensure high speed and high accuracy of the machine control.8 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module MITSUBISHI PLC Programming Manual.
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 Q173DCPU Programming Manual.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic Q173DCPU Programming Manual.
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 Q173DCPU Programming Manual.
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 exisst input / output hysteresis phenomena, i Q173DCPU Manual . 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 MITSUBISHI PLC Programming Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
