Type of input and output terminal.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module. 2 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 A2NCPU-S1 Common Instructions Manual A2NCPU-S1 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 A2NCPU-S1 Common Instructions Manual A2NCPU-S1 Programming Manual .
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 analog quantity and switch quantity oof the controlled object,
Generally an input / output element to take up an input / output point A2NCPU-S1 Common Instructions Manual A2NCPU-S1 Programming 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% A2NCPU-S1 Common Instructions Manual A2NCPU-S1 Programming Manual .
The following describes the centralized control system I/O points of the estimate.
