MELSECNET/10 Network System (Remote I/O network) AJ71LR21 Reference Manual MITSUBISHI AJ71LR21 Manual

Output points: 32 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
32 points / a common end.
38 point terminal station.
With heat protection.
With short circuit protection.
With the surge absorber.
Each scanning process. Focus on the input signal sampling AJ71LR21 Reference Manual. Focus on the output signal to refresh.
Input refresh process AJ71LR21 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.
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 AJ71LR21 Reference Manual.
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.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive AJ71LR21 Reference Manual.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference MITSUBISHI AJ71LR21 Manual. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI AJ71LR21 Manual.
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.
Read only memory MITSUBISHI AJ71LR21 Manual. Manufacturers use, content can not be changed, power does not disappear. Input points: 32 points.
