Embodiment Construction
[0027] In order to make the content of the present invention easier to understand, the following specific examples are used as the present invention.
[0028] FIG. 1 is a block diagram of a multipoint communication system according to an embodiment of the present invention. Referring to Figure 1, Multipoint Communication
[0029] In this embodiment, the master device 110 and the plurality of slave devices 120_1 to 120_N may respectively include microprogrammed controls
[0031] Further, when the user couples the master device 110 and the plurality of slave devices 120_1 to 120_N to multiple points
[0032] Next, when the slave device 120_1 updates its own slave device identification code, the slave device 120_1 can send a confirmation
[0033] And, when the slave device 120_2 updates its own slave device identification code, the slave device 120_2 can also send
[0034] FIG. 2 is a flow chart of the operation of the master device according to an embodiment of the present invention...

The invention provides an identification code numbering method and a multipoint communication system. The identification code numbering method includes the following steps: sending the identification code packet to the multi-point communication bus through the master device; receiving the identification code packet through the multi-point communication bus through the first slave device, and temporarily storing the identification code according to the identification code packet; changing the master device The voltage level of the control output pin of the master device; and when the first slave device judges that the voltage level of the first control input pin coupled to the control output pin of the master device changes correspondingly, the first slave device determines according to the identification code The first slave device identification code of the first slave device is updated. The identification code numbering method and the multipoint communication system of the present invention can enable multiple devices in the multipoint communication system to automatically perform identification code numbering.
Description
Identification code numbering method and multipoint communication system technical field The present invention relates to a kind of coding method, relate in particular to a kind of identification code numbering method and multipoint communication system. Background technique [0002] The data transmission mode between multiple terminal devices in a general industrial system or a multi-device system is usually The plurality of terminal devices are connected by a communication bus, so that the plurality of terminal devices can communicate or exchange data. In this regard, in the process of using the communication bus to connect the plurality of terminal devices for communication or data exchange, the plurality of terminal devices The terminal devices will have different identification numbers, so as to be used as one of the multiple terminal devices basics of device identification. However, in general, the identification code numbering method of the plurality of termina...
