Sensor connector type (E-CON type).
Using industry standard E-CON type.
Simple wiring through sensor connector.
When installing the module can choose to use the DIN guide rail or screw mounting A1SJ71LR21
3 wire sensor input. 7 slots.
Power supply unit.
Q4AR power supply 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 thhe corresponding switching output,
In order to make the system work in a certain order A1SJ71LR21 PDF A1SJ71LR21 Manual .
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 A1SJ71LR21 PDF.
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 Reference Manual .
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 Reference Manual .
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / outputt hysteresis phenomena, i A1SJ71LR21 Reference 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 tthe process of interpretation MITSUBISHI Reference Manual A1SJ71LR21 Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
