Human computer interaction is the interaction between human and machine, which is essentially human and computer A9GT-80V4 PDF datasheet.
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 A9GT-80V4 PDF datasheet. .
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 system containing the computer,
The support software and hardware of the two-way information exchange between human and computer. The interface is defined as the media or means of communication,
Its physical and chemical embodiment is related to the support of software and hardware, such as a graphical display terminal with the mouse, etc.. Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Coaxial data communication line function.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
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 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.
User program storage capacity: it is a measurre of how much the user application can store the number of indicators A9GT-80V4 PDF catalog.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A9GT-80V4 PDF catalog. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
