ンドを受信するまで待機する。Conventionally, in this type of serial bus interface power supply control method, a power-off command for multiple power supplies is
Physical address data that is individually set for each power supply is sent in advance in a command, and the power supply that matches the physical address data included in the command indicates to the power supply control device that the command has been successfully received. “AC”
The power control device responds with “ACK” command.
When the command is received, the physical address data for the next power source following the physical address data is included in the power cut command and transmitted, and the device waits until it receives an "ACK" command from the matching power source.
“ACK”コマンドを受信すると、次に続く物理アドレ

るという欠点がある。In the conventional power supply control method described above, individual physical addresses are sent to multiple power supplies, and after receiving an "ACK" command from a power supply with a matching physical address, the next command is sent. Because this operation is repeated, it takes a lot of time to complete power-off as a system.Furthermore, since power-off instructions are given to each power supply individually,
There is a drawback that it is not possible to simultaneously turn off a plurality of power supplies for each voltage type, and that it is impossible to turn off power supplies for each voltage type in sequence.

実行し、電源切断完了データを送信する。In the power control method of the present invention, physical address data and order data are individually set for multiple power supplies, and a power cut command sent from the power control device is composed of a control code representing a power cut instruction and order data. However, the power-off completion data transmitted from the power supply is composed of a code indicating the completion of power-off and physical address data. During an initialization operation, the power supply control device reads and stores physical address data and order data individually from a plurality of power supplies. The power control device transmits power-off commands in accordance with a predetermined order of power-off. The power supply that has set the order data that matches the received power-off command executes the power-off operation and transmits power-off completion data.
