Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] Referring to Fig. 1, it shows the structure of the system of the present invention, including an address configuration node 11 and multiple device nodes 12, and the address configuration node 11 and multiple device nodes 12 are connected through a bus.

[0041] The address information inside the address configuration node 11 includes a system number code and a list of device node address codes. Wherein, the system number is used to identify the system where the address configuration node is located, which is the same as the system number stored inside the device node 12, and the device node address code list includes the device node address codes of each device node 12 in the system. When a new device node 12 is added in th...

Abstract

The present invention relates to a distribution method for equipment node address codes, comprising the following steps that: an address configuration node in a system configures starting signals are allocated for each equipment node broadcast address; the equipment nodes receives the starting signals and respectively returns a unique confirmation code to the address configuration node; the address configuration node distributes unique equipment node address codes, and broadcasts the equipment node address codes as well as the confirmation codes; the equipment nodes determine that the confirmation codes accord with the own confirmation codes, and saves the equipment node address codes. Meanwhile, the present invention also discloses a distribution system for equipment node address code, as well as an address configuration node. The present invention solves the problem that the prior art is high in error rate when setting address codes, and has the advantages of easy realization, low cost, low error probability, etc.

Description

technical field [0001] The invention relates to the field of device node address code distribution, in particular to a device node address code distribution method and distribution system, and an address configuration node. Background technique [0002] In a process control system or a device test system, there are often a large number of devices of the same type, which are interconnected through a bus, and each device corresponds to a device node. When the device nodes need to exchange data, in order to identify each independent device node, each device node in the system must have a unique identifier, so as to distinguish it from other device nodes. [0003] In the application, it is often used to set the node address for each device node in the system to distinguish other device nodes, that is, each device node contains a device node address code inside, and the device node address code is unique in the system. The device node address code is included in the data sent by...
