Dispositivo y procedimiento de creación de uno o más canales de comunicaciones de baja velocidad utilizando un canal de comunicación en tiempo real

摘要

An intelligent electronic device having a slow speed communications link creates one or more virtual communications channels using unused or dedicated bits from a primary real-time communications channel. The virtual communications channels are used to transport low-speed information, such as fault location information, device configuration information, device revision information, and date / time information.
