Abstract
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.
