Synchronous communication network terminal address searching method

The invention relates to synchronous bus communication and discloses a synchronous communication network terminal address searching method. The method comprises the concrete steps that: a synchronous communication network system is built, wherein the synchronous communication network system comprises a communication host machine and a communication terminal, and the communication host machine and the communication terminal are connected through a synchronous communication bus; the communication host machine sends broadcast commands, the communication terminal carries out self address conversion and then sends the conversion codes to the communication host machine, the communication host machine receives the overlapping of all communication terminal conversion codes, the addresses of all communication terminals are obtained after the analysis, in addition, the addresses are verified with the communication terminals one by one, when one address is the same as the communication terminal address, the address is stored as the communication terminal address, and otherwise, the address is abandoned. After the adoption of the searching scheme provided by the invention, the communication host machine can fast search all equipment in the network no matter how big the communication terminal equipment address is, and the system can enter the normal operation state as fast as possible.
