PLC station distance: 2Km.
Cable type: GI-62.5/125.
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 MITSUBISHI A1SJ71C24-PRF PDF catalog

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 MITSUBISHI A1SJ71C24-PRF PDF catalog.
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 MITSUBISHI A1SJ71C24-PRF PDF catalog.
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 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-to-one correspondence between the ladder diagram and the ladder diagram. Its characteristics are basically consistent with the ladder diagram language. Output type: transistor drain.
Output points: 64 points.
Load voltage: DC12/24.
Load current: 0.1A.
Connection mode: terminal row.
Common public end points: 32.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advanced languages,
But in order to be convenient, the exprression methods of the statement and the types of statements are simplified A1SJ71C24-PRF PDF datasheet.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Needd to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers A1SJ71C24-PRF PDF datasheet. Poor visibility and operability.
