Structured text language is a programming language that describes a program with a structured description of the text A2ACPUP21-S4 Programming Manual .
It is a programming language similar to a high level language A2ACPUP21-S4 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.
Sequential function flow chart language is designed to satisfy the sequential logic control A2ACPUP21-S4 Programming Manual .
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.
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 A2ACPUP21-S4 Programming Manual .
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 complicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced. RS-232:1, RS-422/485:1.
Transmission speed: 0.3 ~ 19.2kpbs.
Computer connection function.
Printer / peripheral device connection, BASIC language function.
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PPLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps A2ACPUP21-S4 Manual.
Design PLC peripheral hardware circuit. A2ACPUP21-S4 Manual.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
