It is not designed for Network such as IEC61850,Hot-Standby, PRP, etc.‡Note: Select a LAN module designed for PRP/HSR/RSTP when the PRP/HSR/RSTPcommunication is required(“L or N” code at position E). When required the Hot-standby communication, select dual LAN modules by referring Positions E and F.Note: Module locations can be identified by positon codes in brackets. For the IED caseexamples, with regard to the stand-alone of MainUnit, a 100Base-TX/1000Base-Tmodule is mounted at C11 when “14” code is chosen at Positon E&F. To identify thelocations C11—C15 in the IED, see Figure 4.1-1 (p. 250).
