Ethernet Network Redundancy IEC 61850

The EN100 module is used on Reyrolle devices to provide Ethernet/IEC61850 functionality. The EN100 supports
RSTP, PRP & HSR redundancy protocols.
All IEC61850 variants are delivered with the EN100+ (Plus) module and firmware 4.21 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 Userguide.
Depending on the EN100 module type and Firmware version, the following protocol options are available:
Interface Type
Electrical RJ45 EN100+
Electrical RJ45 EN100+
Optical EN100+
Optical EN100+

RSTP – Rapid Spanning Tree Protocol
RSTP is a redundancy protocol with a minimal response time that has been standardized in IEEE-802.1D (2004).
The reconfiguration time depend on the topology and start at 50ms.
RSTP need to be enabled on the device within Reydisp Manager (See Reydisp Manager userguide). Network
rings with up to 30 devices is possible.
