Man machine interface (Machine Interaction Human, referred to as HMI), also known as the user interface or user interface,
Is a communication interface between human and computer,
Is an important part of the computer system MITSUBISHI A1SJ71AT21B PDF datasheet A1SJ71AT21B
Is a medium for interaction and information exchange between the system and the user,
It realizes the transformation between the internal form of information and the acceptable form of human being.
Where there is a man-machine interface in the field of human computer information exchange. Input points: 32 points MITSUBISHI A1SJ71AT21B PDF datasheet.
Voltage: AC100 ~ 120V.
Current: 12mA.
Response time: 25ms.
32 points / a common end.
38 point terminal station.
CE certification.
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. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI A1SJ71AT21B PDF datasheet.
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 consider the best performance to price ratio, a reasonable choice of PLC.
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.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the componentt image register are changed with the change of the execution of the program A1SJ71AT21B PDF catalog.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A1SJ71AT21B PDF catalog.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
