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 A975GOT-TBD Hardware A975GOT-TBD
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.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF A975GOT-TBD Hardware.
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.
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 A975GOT-TBD Hardware.
Mainly used for other programming languages more difficult to achieve the user 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. Cable type: cable or twisted pair.
A1SJ71PT32-S3 and A1SJ71PT32-S3 are the main control module of MELSECNET/MINI-S3,
The main PLC in the network can control 64 remote I/O modules.
The main control module carries on the high speed data communication to the remote module on the connection network.
Each PLCCPU can use a number of main control modules,
But up to no more than the maximum allowed by the main I/O CPU points.
A1SJ71PT32-S3 can be used in the cable system can also be used in twisted pair cable system;
A1SJ71T32-S3 can only be used in twisted pair cable network.

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-tto-one correspondence between the ladder diagram and the ladder diagram A975GOT-TBD User's Manual A975GOT-TBD User's Manual. Its characteristics are basically consistent with the ladder diagram language.
