RS-422 connection (QnA/A/FXCPU direct connection, computer connection, micro computer connection).
No clock function.
Applicable models: A985 (-V) /975/970/960GOT A1SJ71QLP21GE PDF. PLC station distance: 500M.
Cable type: coaxial cable.
The function of the MELSECNET interface module is to connect the main CPU PLC to the MELSECNET data communication system.
As long as the switch on the component to set,
Can determine the CPU PLC is as the main station or in situ station A1SJ71QLP21GE
There are two modules available for selection: one is the connection of the optical cable network and the network of the coaxial cable.
For a ANSCPU, up to only a piece of interface components can be inserted, A2ASCPU can be inserted 2 A1SJ71QLP21GE PDF.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely useed 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 A1SJ71QLP21GE PDF A1SJ71QLP21GE 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 MITSUBISHI User's Manual.
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 MITSUBISHI User's Manual.
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 mnemmonic 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 A1SJ71QLP21GE Manual A1SJ71QLP21GE User's Manual. Its characteristics are basically consistent with the ladder diagram language.
