1. A system for communicating a network event and monitored system data from an Intelligent Electronic Device (IED) to a central monitoring system comprising:

  • a plurality of IEDs in communication with and separate from monitored equipment,gathering monitored equipment information therefrom for producing monitored system data relating to a status of an electric power distribution system, and,transmitting the monitored system data;

    an access controller in communication with the plurality of IEDs and configured to receive the monitored system data from the plurality of IEDs, and further receiving the network event, the access controller comprising;

    an IED interface to communicate with the plurality of IEDsa central monitoring system communications interface to transmit the monitored equipment information to the central monitoring system according to a Supervisory Control and Data Acquisition (SCADA) format used by the central monitoring system;

    an information system communications interface to communicate with an information system according to a non-SCADA format used by the information system;

    a processor; and

    a logic engine receiving the network event according to the non-SCADA format, transmitting the network event to the information system in the non-SCADA format, data mapping the network event into the SCADA format, and transmitting the mapped network event to the central monitoring system through the central monitoring system communications interface in the SCADA format;

    wherein the SCADA format and the non-SCADA format comprise distinct communication protocols and the central monitoring system is incapable of communication using the non-SCADA format.
