PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control MITSUBISHI A1SJ71AT21B.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control A1SJ71AT21B
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity MITSUBISHI A1SJ71AT21B.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal MITSUBISHI A1SJ71AT21B.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing A1SJ71AT21B MITSUBISHI.
This requires the resolution of the analog unit and the standard electrical signal A1SJ71AT21B MITSUBISHI. Cable type: twisted pair.
A1SJ71PT32-S3 and A1SJ71PT32-S3 are the main control module of MELSECNET/MINI-S3,
The main PLC in the network can control 64 remote I/O modules.
The main control module carries on the high speed data communication to the remote module on the connection network A1SJ71AT21B MITSUBISHI.
Each PLCCPU can use a number of main control modules,
But up to no more than the maximum allowed by the main I/O CPU points.
A1SJ71PT32-S3 can be used in the cable system can also be used in twisted pair cable system;
A1SJ71T32-S3 can only be used in twisted pair cable network.
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 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 MITSUBISHI A1SJ71AT21B A1SJ71AT21B. Its characteristics are basically consistent with the ladder diagram language.
