The external model design model of creating the system function is mainly to consider the data structure, the overall structure and the process description of the software,
The interface design is usually only used as accessories, only on the user''s situation (including age, gender, mental status, education level, personality, ethnic background and etc A3ACPU datasheet PDF catalog A3ACPU PDF datasheet A3ACPU ) to understand, to design an effective user interface;
According to the user model of the future system of the end user (for short),
In the end, it is consistent with the system image (external characteristic) of the system after the system is realized,
Users can be satisfied with the system and be able to use it effectively;
When the user model is established, the information given by the system should be considered,
System mapping must accurately reflect the syntax and semantic information of the system A3ACPU datasheet PDF catalog A3ACPU PDF datasheet.
In short, only to understand the user, to understand the task in order to design a good man-machine interface A3ACPU datasheet PDF catalog A3ACPU PDF datasheet. 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.
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 programming language is used to represent mnemonnic 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 A3ACPU datasheet PDF catalog A3ACPU PDF datasheet A3ACPU datasheet PDF catalog A3ACPU PDF datasheet. Its characteristics are basically consistent with the ladder diagram language.
