MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process A2NCPU Hardware Manual A2NCPU User's Manual A2NCPU
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program. Output points: 24 points.
Voltage: DC24V/AC240V, 2A/1 point, 4A/ public end A2NCPU Hardware Manual A2NCPU User's Manual.
OFF leakage current: 0mA.
Output type: relay output.
Response time: 12ms.
8 points / a common end.
50 point terminal station.
CE certification.
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 A2NCPU Hardware Manual A2NCPU 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.
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.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should considder the best performance to price ratio, a reasonable choice of PLC A2NCPU Hardware Manual A2NCPU User's Manual.
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 A2NCPU Hardware Manual A2NCPU User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
