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.
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.
PLC user program is designed according to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design.
As long as the user can master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram. Its characteristics are basically consistent with the ladder diagram language.
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.
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 the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced.
Output type: bidirectional controlled silicon.
Output points: 8 points.
Load voltage: AC100-240.
Load current: 1A.
Connection mode: terminal row.
Common public end points: 1.
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 A1S62RD4N. 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 A1S62RD4N
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 A1S62RD4N.
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 A1S62RD4N. Poor visibility and operability MITSUBISHI Temperature input module. Type of input: DC source.
Input points: 16 points.
Input voltage: DC24.
Input current: 7mA.
Connection mode: terminal row MITSUBISHI Temperature input module.
Common common point: 16.
Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions MITSUBISHI Temperature input module.
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in accordance with the functional flow of the order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the compllicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced MITSUBISHI A1S62RD4N A1S62RD4N.
