    • The PLC 20 adaptor corresponding to a power line communication apparatus has four PLC bridges 30A to 30D, each of which is correspondingly connected to Ethernet communication connectors 26A to 26D, operation mode setting switches 27A to 27D, display units 28A to 28D. Each PLC bridge 30A to 30D includes a PLC modem unit 301, a bridge unit 302, an Ethernet IF unit 303, and a communication control unit 304. The communication control unit 304 obtains data type information on the basis of setting conditions of switches 27A to 27D corresponding to each communication port. Since the time slot required for the communication link corresponding to the communication port of the PLC network can be obtained on the basis of the data type information, the reservation request can be transmitted to the control terminal.
    • 对应于电力线通信装置的PLC 20适配器具有四个PLC电桥30A至30D,每个PLC电桥相应地连接到以太网通信连接器26A至26D,操作模式设置开关27A至27D,显示单元28A至28D。 PLC桥30A至30D包括PLC调制解调器单元301,桥单元302,以太网IF单元303和通信控制单元304.通信控制单元304基于开关27A至 27D对应于每个通信端口。 由于可以基于数据类型信息获得与PLC网络的通信端口相对应的通信链路所需的时隙,所以可以将预约请求发送到控制终端。
