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.
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 MITSUBISHI A1SJ71UC24-R4 A1SJ71UC24-R4
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 MITSUBISHI A1SJ71UC24-R4.
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 A1SJ71UC24-R4.
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 MITSUBISHI Computer communication module.
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 MITSUBISHI Computer communication module. 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 MITSUBISHI Computer communication module. Its characteristics are basically consistent with the ladder diagram language. Type of input: DC leakage.
Input points: 8 points.
Input voltage: DC24.
Input current: 7mA.
Output type: transistor drain type.
Output points: 8 points.
Common public end points: 8.
PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control.
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.
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.
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 signaals 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 A1SJ71UC24-R4.
So the standard telecommunication number, the conversiion between the number of operations to use a variety of computing MITSUBISHI A1SJ71UC24-R4.
This requires the resolution of the analog unit and the standard electrical signal.
