Abstract:
1. A network electric device for communicating with another network electric device on a network, the network electric device comprising a processor configured for executing at least an application layer, a network layer, a data link layer, a physical layer, an application software, a network management sub-layer, and a parameter management layer, wherein the application layer handles a message for controlling or monitoring the network electric device or the other network electric device, and the application layer communicating with the application software and communicating with the network layer, wherein the application layer transmits a APDU (application protocol data unit) to the network layer; wherein the network layer performs at least an address management function and a routing control function and the network layer communicating with the data link layer, wherein the network layer transmits a NPDU (network protocol data unit) to the data link layer, wherein the NPDU comprises a start indicating field, a length field, and an end indication field, the start indicating field indicating a start of the NPDU, the length field specifying a length of the NPDU, and the end indication field indicating an end of the NPDU, wherein when a data having a length corresponding to the length field is received by the processor and the end indication field is not received by the processor, the processor considers this as a data error wherein the data link layer accesses a transmission medium, the data link layer communicating with the physical layer, wherein the physical layer provides a physical interface between the network electric device and the other network electric device, wherein the application software performs an intrinsic function of the network electric device, wherein the network management sub-layer transmits a parameter set-primitive to the parameter management layer, the parameter set-primitive including a destination layer field and a parameter field indicating which parameter is to be set, and the destination layer field indicating one of the application layer, the network layer, the data link layer, and the physical layer, and wherein when the parameter management layer receives the parameter set-primitive, the parameter management layer processes the received parameter set-primitive according to the destination field and the parameter field included in the parameter set-primitive.
