This disclosure pertains to systems and methods to detect network errors in a parallel redundant protocol (PRP) network. A node-level redundancy error subsystem of an intelligent electronic device (IED) maintains records (e.g., counts) of information associated with missing duplicate frames expected from node devices on the PRP network via redundant first and second local area networks (LANs). Non-zero counts of missing duplicate frames may be identified as network errors.

Parallel redundancy protocol error detection

A system and method for optimizing the handling of data on a priority basis within an intelligent electronic device is disclosed. A FIFO receives messages and the messages are each associated with a subscription identifier. The messages are then routed to and stored in buffers, each associated with a subscription identifier.

Intelligent electronic device with segregated real-time ethernet

Provided is an apparatus and method for customization of a protective device. The apparatus and method includes coupling programmer programmable memory to a microprocessor for processing select logic schemes. The programmer programmable memory is adapted to be modifiable by only a programmer of said protective device. Elements associated with some of the logic schemes are implemented into the programmer programmable memory in the form of a compiled settings structure having a plurality of allocation fields.
