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 A173UHCPUN Fundamentals Manual A173UHCPUN Programming Manual A173UHCPUN
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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 A173UHCPUN Fundamentals Manual A173UHCPUN Programming 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.
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 A173UHCPUN Fundamentals Manual A173UHCPUN Programming 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. Series Name: A960GOT.

Human computer interaction is the interaction between human and machine, which is essentially human and computer.
Or from a broader perspective: human computer interaction is the interaction between people and machines that contain computers.
Specifically, the two-way communication between the user and the computer machine,
Using a certain symbol and a liquid crystal screen to be used as a man-machine interface display
Action to achieve, such as the hit key, move the mouse, display the symbol / graphics on the screen, etc..
This process consists of several sub processes: identifying the interaction object, understanding the interaction object, grasping the object modality, information adaptation and feedback, etc.;
The human computer interface is the communication media or means between the user and the computer systemm containing the computer,
The support software and hardware of the two-way information exchange between human and computer A173UHCPUN Fundamentals Manual A173UHCPUN Programming Manual. The interface is defined as the media or means of communicatioon,
Its physical and chemical embodiment is related to the support of software and hardware, such as a graphical display terminal with the mouse, etc A173UHCPUN Fundamentals Manual A173UHCPUN Programming Manual. .
