6F2S1931 (0.20)Centralized GRB200(Soft: 030, 031, 032, 033, 034)- 530 -Settings [PortA_AdminEdge] and [PortA_AutoEdge] †: are provided for a port, which isable to operate as ‘Edge’. Edge will not be joined for the spanning tree computation, soEdge port is able to have the communication immediately when the LAN connection isstarted (link-up; Notice that the user has to know that no loop will occur in the network,in advance). When On is set for the [PortA_AdminEdge], the Port A unconditionallyoperates as Edge. PortA can detect Edge port itself, when On is set for the[PortA_AutoEdge].Setting [PortA_PathCost]: is used to set the distance for the root bridge (path cost), whenthe port is used in the LAN network, actually. As a rule, the setting value depends on thecommunication bandwidth.Setting [PortA_Priority]: is set a priority value for the port. Similar to the setting[BridgePrioriy], a port having the smallest number can have the highest priority. Notethat a number can be set in 16 steps†Note: Port A (connection for LAN_A) is located at C11 of IED. The second Port B(connection for Port B) is located at C12 and has similar settings. See Table 10.2-6for the IP addresses examples. The user can find the contents about LANcommunication module in ChapterTechnical description: Signal processing andcommunication module.
