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 AJ71LP21GE AJ71LP21GE
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 AJ71LP21GE . .
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 AJ71LP21GE . 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.. Twisted pair / rubber insulated cable.
Single bus.
LINK MELSEC-I/O (control unit).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. Output points: 24 points.
Voltage: DC24V/AC240V, 2A/1 point, 4A/ public end.
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.
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 requiremennts,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ71LP21GE Reference 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 AJ71LP21GE Reference Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
