MITSUBISHI LD77MH4
Function: RS-485 communication.
Adapter for connecting the left extension function of the CPU module.
CPU module can be connected to the left side up to 6 units. PLC station distance: 1Km.
Cable type: QSI-200/250.
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, you can determine the CPU PLC is as a main station or in situ station LD77MH4
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 LD77MH4.
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 LD77MH4.
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 characteeristics of instruction tablee 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-oone correspondence between the ladder diagram and the ladder diagram LD77MH4 LD77MH4. Its characteristics are basically consistent with the ladder diagram language.
