A1SI61 High speed interrupt module

3C-2V/5C-2V coaxial cable single bus remote I/O network (remote I/O station).
Q mode.
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 A1SI61.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register A1SI61
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
Semiconductor circuit with memory function A1SI61.
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
User memory: user program storage area and work data storage area A1SI61.
Composed of random access memory (RAM). User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years. 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.
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.
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 progrramming 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-one correspondence between the ladder diagram and the ladder diagram A1SI61 A1SI61. Its characteristics are basically consistent with the ladder diagram language.
