Component 3, by control assembly 4 mutually transmit data, and it is each by control assembly 2, by control assembly 3, between by control assembly 4 not
Therefore it interferes with each other.In addition, numerical control device 1 of the present invention is also not necessarily to broadcast data to after by control assembly 2, then sequentially carry out
Will be controlled by component 3, by the data transfer needed for control assembly 4 to by control assembly 3, by control assembly 4, therefore, the present invention
Numerical control device will not reduce data messaging efficiency and reduce flexibility in use.
Main control interface 13 can connect simultaneously it is different types of by control assembly 2, by control assembly 3, by control assembly 4
By control interface 21, by control interface 22, by control interface 23, by control interface 24, by control interface 31, by control interface
32, by control interface 41, by control interface 42, so there is no need to because by control assembly 2, by control assembly 3, by control assembly 4 by
Control interface 21, by control interface 22, by control interface 23, by control interface 24, by control interface 31, by control interface 32,
By control interface 41, different by control interface 42 type and need to additionally increase main control interface newly, because without additionally increasing cost,
Wherein, it is connect by control interface 21, by control interface 22, by control by control assembly 2, by control assembly 3, by control assembly 4
Mouthfuls 23, by control interface 24, by control interface 31, by control interface 32, by control interface 41, by the type of control interface 42
It is：The serial communication bus of the types such as RS232, RS422, RS485, it is of the invention herein not limit.
Main control interface 13 is a serial main control interface, the e.g. serial main control interface of a DB9 types, serial master
The type of control interface can be replaced according to user's demand, and the present invention does not limit herein.
Three Ports are arranged by control interface quantity in response to by control assembly in main control interface 13, connectivity port number
It measures and can be arranged on demand by control component count, the present invention does not limit herein.
In conclusion each Port of main control interface of the present invention and each data transfer between by control assembly
It is also independent to transmit, it can be ensured that each to be interfered with each other between by control assembly.Numerical control device of the present invention
Main control interface can be connected to various different types of by control interface, therefore main control interface is not necessarily to because by controlling interface type not
Additional increase main control interface quantity is needed together, thus reduces cost.
