Abstract
An intelligent electronic device (IED) includes a power monitoring circuit operative to monitor a parameter of a portion of a power distribution system and generate an analog signal representative thereof. An analog to digital converter couples with the power monitoring circuit and operates to convert the analog signal to a digital signal representative thereof. A processor couples with the analog to digital converter and operates to implement power management functionality and generate power management data. The IED also includes a first non-volatile memory operative to store first program code for execution by the processor. The processor operates to access a second non-volatile memory in the external function module via the interface. The second non-volatile memory includes a second program code and operates to replace the first program code in the first non-volatile memory with the second program code.
