Abstract: An intelligent electronic device (IED) is provided. The IED includes a metering sub-assembly and an input base module sub-assembly. The metering sub-assembly is hinged to the input base module sub-assembly, where when in an open position, various cables, connectors, and input/output cards/modules are accessible. Various input/output cards/modules are interchangeable to add/change functionality and/or communication capabilities to the IED. In one embodiment, a communication card is provided with at least one antenna disposed internal or external to a housing of the IED.

Abstract: A system and method is provided for simultaneous communications on Modbus and DNP 3.0 over Ethernet for an electronic power meter. The system incorporates one or more protocol wrappers to provide compatibility with both Modbus and DNP based applications. The system removes the appropriate wrappers and routes the incoming data packet to its destination. Additionally, the system also wraps outgoing response packets with the appropriate protocol wrapper based on the related data packet wrappers.

Abstract: Apparatuses, systems, and methods for providing security in an intelligent electronic device (IED) are provided. In one aspect of the present disclosure, an IED is provided including at least one processor that receives a communication via a communication interface, the communication including an unencrypted file and a digital signature. The at least one processor decrypts the digital signature to obtain a first value, executes a hash function on the unencrypted file to obtain a second value, determines if the first value and second value match, and updates at least one firmware package stored in at least one memory of the IED with the unencrypted file if it is determined that the first value and the second value match.
