A1SJ71AT21B Melsecnet interface module MITSUBISHI A1SJ71AT21B

10BASE2.
Q mode.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types off machinery or production process A1SJ71AT21B.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program A1SJ71AT21B. Output type: transistor output, drain type.
Output points: 32 points.
OFF leakage current: 0.25mA.
Output protection function A1SJ71AT21B.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool MITSUBISHI A1SJ71AT21B.
Cable type: twisted pair cable.
The function of the MELSECNET interface module is to connect the main CPU PLC to the MELSECNET data communication system MITSUBISHI A1SJ71AT21B.
As long as the switch on the component to set,
Can determine the CPU PLC is as the main station or in situ station.
There are two modules available for selection: one is the connection of the optical cable network and the network of the coaxial cable MITSUBISHI A1SJ71AT21B.
For a ANSCPU, up to only a piece of interface components can be inserted, A2ASCPU can be inserted 2.
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.
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 usinng 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 A1SJ71AT21B. Its characteristics are basically consistent with the ladder diagram language.
