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 A970GOT-SBA PDF. 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 A970GOT-SBA
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
The function module is used to represent the function of the module,
Different function modules have different functions A970GOT-SBA PDF.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and complex control logic,
Because thee function module diagram can clearly express the function relation, the programming debugging time is greatly reduced A970GOT-SBA PDF MITSUBISHI Operating Manual A970GOT-SBA Manual. 3C-2V/5C-2V coaxial dual ring remote I/O network (remote I/O station).
Q mode.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program MITSUBISHI Operating Manual.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU MITSUBISHI Operating Manual.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
Semiconductor circuit with memory function.
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user programm to do the compiler to compile the process of interpretation A970GOT-SBA Operating Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
User memory: user program storage area and work data storage area.
Composed of random access memory (RAM) A970GOT-SBA Manual. User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years.
