Synchronous communication network terminal address searching method

[0023] Specific embodiment 1: If there is only one communication terminal device on the synchronous communication network, the address of the device is 10000001 (0x989681 in hexadecimal). First, the communication host sends a broadcast command. After receiving the command, the communication terminal calculates its own address conversion code as (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x02), And send the conversion code to the communication bus. The communication host receives the conversion code and restores it to a hexadecimal address of 0x989681, then the communication host sends the address to the communication terminal, and the communication terminal responds to the address, then the communication host records the address of the communication terminal. The entire communication search process only needs to send two communication commands, which is very fast.

[0024] Embodiment 2: If there are two communication terminal devices on the synchronous communication network, the addresses of the two communication terminal devices are 10000001 (0x989681 in hexadecimal) and 10000002 (0x989682 in hexadecimal). First, the communication host sends a broadcast command. After receiving the command, the two communication terminals calculate their address conversion codes as (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x02 ) and (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x04), they send their own address conversion codes to the communication bus at the same time, and the communication host receives the two communications The superposition of terminal address conversion codes is (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x06), and then parses and restores two communication terminal device addresses, which are 0x989681 and 0x989682 respectively . Then the communication host sends
