China is the world''s biggest market for human machine interface,
But it is not the highest sales market in the world,
This shows that the low-end user interface in China has a large share of A161 Manual A161 User's Manual A161
In recent years, the rapid development of national brands, to take a low price and other strategies, is a massive attack on the low end of the market,
Has occupied the dominant position in the low-end market, has won the recognition of the majority of users.
International brands are also gradually developing its economic products, in order to seize the share of the low-end market A161 Manual A161 User's Manual.
Therefore, in the low-end market steady,
The overall performance of the domestic human machine interface manufacturers showing a rapid growth of the state. 5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program A161 Manual A161 User's 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.
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.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the anaalog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A161 Manual A161 User's Manual.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% A161 Manual A161 User's Manual.
The following describes the centralized control system I/O points of the estimate.
