8 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 A4UCPU User's Manual.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic A4UCPU
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 A4UCPU User's 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 A4UCPU User's Manual.
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 MITSUBISHI A4UCPU Manual MITSUBISHI A4UCPU Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear. RS-422 1 channel, RS-422/485 1 channel.
Transfer speed: 0.3-19.2kbps.
Equipment layer / field bus CC-Link device layer is the PLC and other control devices and sensors and drive devices connected to the field network,
Network for the lowest layer of the whole network system MITSUBISHI A4UCPU Manual .
Using CC-Link field bus connection, the number of wiring is greatly reduced,
Improve the maintainability of the system.
And, not just the amount of data ON/OFF and other switches,
Can also be connected to the ID system, bar code reader, inverteer, man-machine interface and other intelligent devices,
From the completion of a variety of data communication, the management of the terminal production information can be realized,
On the centralized management of the state oof the machine movement,
Make maintenance work efficiency also greatly improved A4UCPU User's Manual A4UCPU Hardware.
Q series PLC in the use of CC-Link function better,
And easier to use.
