Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance A3NCPUP21 Common Instructions Manual A3NCPUP21 Programming Manual .
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage A3NCPUP21
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load A3NCPUP21 Common Instructions Manual A3NCPUP21 Programming Manual .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,

Man machine interface is the interface between man and machine in the field of information exchange and function contact or influence,
Information exchange, 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.
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 solutioon,
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 A3NCPUP21 Common Instructions Manual A3NCPUP21 Programming Manual A3NCPUP21 Common Instructions Manual A3NCPUP21 Programming Manual .
It realizes the transformation between the internal form of information and the acceptable form of human being.
