The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment MITSUBISHI PLC Programming Manual A1NCPUR21
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students MITSUBISHI PLC Programming Manual.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Structured text language is a programming language that describes a program with a structured description of the text MITSUBISHI PLC Programming Manual.
It is a programming language similar to a high level language. In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system.
Mainly used for other programming languages more difficult to achieve the user program A1NCPUR21 Programming 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 A1NCPUR21 Programming Manual.
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. Output type: transistor drain A1NCPUR21 Programming Manual.
Output points: 16 points.
Load voltage: DC12/24.
Load current: 0.1A.
Connection mode: terminal row.
Common public end points: 8.
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 expressionn methods of the statement and the types of statements are simplified A1NCPUR21 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 MITSUBISHI PLC Programming Manual. Poor visibility and operability.
