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 A73CPU-S1 Fundamentals Manual A73CPU-S1 Programming Manual A73CPU-S1
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 A73CPU-S1 Fundamentals Manual A73CPU-S1 Programming Manual. .
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 A73CPU-S1 Fundamentals Manual A73CPU-S1 Programming Manual. 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.. Output type: transistor drain.

Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advanced languages,
But in order to be convenient, the expression methods of the statement and the types of statements are simplified A73CPU-S1 Fundamentals Manual A73CPU-S1 Programming Manual.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Needd to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers A73CPU-S1 Fundamentals Manual A73CPU-S1 Programming Manual. Poor visibility and operability.
