An intelligent electronic device segregates urgent data frames from non-urgent data frames on reception so that the urgent data frames may be handled with greater priority. A switching device is disposed between an external network interface and multiple internal network ports. Based on a network data type indicia, urgent data frames are routed to one of the ports, and non-urgent data frames are routed to another port. A processor coupled to the internal network ports handles urgent data frames before handling any non-urgent data frames.

Intelligent electronic device with segregated real-time ethernet

A system for controlling and automating an electric power delivery system by executing time coordinated instruction sets to achieve a desired result. A communication master may implement the execution of time coordinated instruction sets in a variety of circumstances. The communication may be embodied as an automation controller in communication with intelligent electronic devices (IEDs). The communication master may also be embodied as an IED that is configured to coordinate the actions of other IEDs. The time coordinated instruction sets may include steps for checking status of power system equipment before executing. The time coordinated instruction sets may include reactionary steps to execute if one of the steps fails. The time coordinated instruction sets may also be implemented based on a condition detected in the electric power delivery system, or may be implemented through high level systems, such as a SCADA system or a wide area control and situational awareness system.

Electric power system automation using time coordinated instructions

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.

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.

Method and apparatus for customization

A power system device-to-device direct communication system comprises a first intelligent electronic device with a processor and a transmit module. Software within the processor maintains a list of 'virtual outputs,' which correspond to a number of data channels maintained within the transmit module. The second intelligent electronic device receives the data channels from the first intelligent electronic device and extracts the virtual output bits. The second intelligent electronic device then adjusts a group of its own output contacts in accordance with the received virtual output bits.
