The choice between the HSR and PRP redundancy protocols depends on the required functionality, cost and complexity. 

The self-healing Ethernet ring solution enables a cost-efficient communication ring controlled 

by a managed switch with standard Rapid Spanning Tree Protocol (RSTP) support. 

The managed switch controls the consistency of the loop, 

routes the data and corrects the data flow in case of a communication switch-over. 

The relays in the ring topology act as unmanaged switches forwarding unrelated data traffic. 

The Ethernet ring solution supports the connection of up to 30 615 series relays.

If more than 30 relays are to be connected, it is recommended to split the network into several rings. 

The self-healing Ethernet ring solution avoids single point of failure concerns and improves the reliability of the communication.

For optimized control and reliable operation of your switchyard, the REC670 is your best choice for transmission applications.

REC670 integrates advanced voltage control for transformers in a substation in a single IED. 

The IEDs feature a large HMI for local control and instant access to important data, 

such as settings, events and disturbance information.

The outstanding I/O capability in REC670 enables control of several bays with complete measurement with only one IED. 

For instance, one REC670 IED is capable of handling control of all apparatuses 

in one entire diameter in 1 ½ breaker arrangement including breaker failure protection for all breakers.

The REF 543 feeder terminal is designed for protection, control, 

measurement and supervision in medium voltage networks.

The REF 543 feeder terminal can be used with different kinds of switchgear, 

including single busbar, double busbar and duplex systems.

The data communication properties include the following communication standards: 

SPA bus, LON bus, IEC 60870-5-103. IEC 61850 via SPA-ZC 400. 

Profibus DPV1 via SPA-ZC 302. DNP 3.0 and Modbus communication with higher level equipment. 

Further, the LON communication together with the PLC functions minimizes the need for hardwiring between the feeder terminals.
