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 MITSUBISHI A1SC07B. 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 A1SC07B
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 MITSUBISHI A1SC07B.
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.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Need to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers MITSUBISHI A1SC07B. Poor visibility and operability MITSUBISHI Extension cable. 3C-2V/5C-2V coaxial cable single bus 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 Extension cable.
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 MITSUBISHI Extension cable.
And then combine the data and the program with CPU.
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 A1SC07B.
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) MITSUBISHI A1SC07B. User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years.
