Interface: RS232C.
Transmission distance: 15 meters.
A1SJ71UC24-R2/R4/PR computer communication components can communicate with PLC, such as computers and other external intelligent devices, and the components are as follows:
Full / half duplex transmission.
4 special communication protocols.
No protocol and bidirectional mode AD75P3 datasheet PDF catalog AD75P3 PDF datasheet.
Protocol selection switch function AD75P3
The optional baud rate, the highest 19.2K.
Since the echo diagnostic test. 5 slots.
To install the power supply.
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 AD75P3 datasheet PDF catalog AD75P3 PDF datasheet.
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.
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 AD75P3 datasheet PDF catalog AD75P3 PDF datasheet.
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 exist input / output hysteresis phenomena, i AD75P3 datasheet PDF catalog AD75P3 PDF datasheet. 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 AD75P3 datasheet PDF catalog AD75P3 PDF datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
