Redundancy Protocols Gateway (PRP/HSR)

SIC-A provides any-to-any protocol conversion that permit the integration of equipment with proprietary and legacy protocols in a modern infrastructure with the most recent protocols and redundant topologies.

SIC-A can work as a multi-protocol conversor, as an unmanaged Redbox or as a redundant protocol gateway.

SIC-A can manage upto 3000 data points of the most common protocols (Modbus, IEC 60870, DLMS, DNP3,...) or upto 800 data points of advanced protocols as IEC 61850.

The device provides with HSR (High-availability Seamless Redundancy) is one of the chosen redundancy protocols for the substation automation as per the IEC 61850 standard. This redundancy is the evolution of the existing Parallel Redundancy Protocol (PRP).

It is especially suited for applications that demand high availability and very short switch over time because it provides zero recovery time in case of the failure of any component. A good example of application may be the protection of automatized electrical substations or the control of synchronized drives, for instance.
