MITSUBISHI A1SJ71E71-B2-S3 Ethernet interface module

Program memory capacity 14K.
Input and output points to the maximum 512 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage MITSUBISHI A1SJ71E71-B2-S3 A1SJ71E71-B2-S3 SRAM+E2PROM memory card.
RAM capacity: 32KB.
E2PROM capacity: 32KB. By MELSECNET/B I/O can be decentralized control.
In a main PLC station this module can control up to 512 I/O points.
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 MITSUBISHI A1SJ71E71-B2-S3.
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 A1SJ71E71-B2-S3.
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 laanguage 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 A1SJ71E71-B2-S3 A1SJ71E71-B2-S3. Its characteristics are basically consistent with the ladder diagram language.
