Ethernet Network Redundancy Iec 61850 - Siemens Argus 7SR21 Technical Manual

Ethernet Network Redundancy IEC 61850

The EN100+ module is used on current Reyrolle devices (from 7SR21/22 hardware /DD) to provide
Ethernet/IEC61850 functionality. The RJ45 electrical EN100+ supports PRP redundancy protocols. The Duplex-
LC Optical EN100+ also supports RSTP and HSR redundancy protocols.
Earlier 7SR21/22 (/CC) devices were manufactured with the EN100 (not EN100+) module and the electrical
version cannot support redundancy. The optical version can support redundancy if firmware is updated. Earlier
devices do not support the EN100+ module cannot be updated by simply exchanging the EN100 module.
All current 7SR21/22 IEC61850 variants are delivered with the EN100+ (Plus) module and firmware 4.24 or later.
The EN100 module firmware can be updated by connecting to the relay via the rear Ethernet port. For more
information on connecting to the relay via the Ethernet port, please see the Reydisp Manager User guide.
Depending on the EN100 module type and Firmware version, the following protocol options are available:
