Cable type: 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 A1SJ71AR21  PDF.
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 A1SJ71AR21 
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 popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechaniical 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 A1SJ71AR21  PDF A1SJ71AR21  Manual .
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 A1SJ71AR21  PDF.
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 MITSUBISHI User's Manual.
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 MITSUBISHI User's Manual. 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 mnemoniic 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 betweeen the ladder diagram and the ladder diagram MITSUBISHI User's Manual A1SJ71AR21  Manual A1SJ71AR21  User's Manual. Its characteristics are basically consistent with the ladder diagram language.
