Man machine interface is the interface between man and machine in the field of information exchange and function contact or influence,
Information exchangee, functional contact or mutual influence, the hard contact and soft touch of a person and machine,
This interface includes not only the direct contact point line side,
It also includes the function of remote information transmission and control AJ71C24-S3 AJ71C24-S3.
The man-machine interface is the central link in the man-machine system,
Mainly from the safety engineering branch of the safety ergonomics to study and put forward the basis for the solution,
And over the safety engineering equipment engineering, safety management engineering and safety systems engineering to study the specific solutions and measures to the safety of human computer science and technology AJ71C24-S3.

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 AJ71C24-S3.
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 MITSUBISHI AJ71C24-S3.
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 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.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal.
RS-232:1, RS-422/485:1.
Transmission speed: 0.3 ~ 19.2kpbs.
Computer connection function.
Printer / peripheral device connection, BASIC language function.
How to choose MITSUBISHI PLC.
