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 A2UCPU-S1 datasheet PDF catalog A2UCPU-S1 PDF datasheet.
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 A2UCPU-S1 datasheet PDF catalog A2UCPU-S1 PDF datasheet.
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. Poor visibility and operability. RS-232 1 channel.
RS-422/485 1 channel.
Transmission speed: 2 channels.
At the same time the use of 115.2kbps may.
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.
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.
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 program to do the compiler to compile the prrocess of interpretation A2UCPU-S1 datasheet PDF catalog A2UCPU-S1 PDF datasheet.
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) A2UCPU-S1 datasheet PDF catalog A2UCPU-S1 PDF datasheet. User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years.
