The embodiments of the present invention provide a board communication method and system, and a board. The board is plugged in any slave device slot on a backplane, and the board includes a memory, a board in-position detection circuit, and a chip-select enable circuit; the board in-position detection circuit is connected to the master device through an in-position signal cable when the board is plugged into a slave device slot, so that the master device obtains an in-position signal of the board through the in-position signal cable; the chip-select enable circuit is configured to obtain an address signal corresponding to the slave device slot through an address signal cable when the in-position signal of the board is "active"; the memory is configured to configure a device chip-select enable address of the board according to the address signal corresponding to the slave device slot and obtained by the chip-select enable circuit, and communicate with the master device through a communication bus. The embodiments of the present invention further provide another board and another board communication system and method. The embodiments of the present invention implement automatic identification and allocation of device chip-select enable addresses of slave devices. |
