Abstract
A system for monitoring and controlling an electrical distribution network comprises an electrical distribution substation having a local area network (LAN), a feeder subsystem and a gateway. The feeder subsystem is coupled to the substation and receives electrical energy therefrom for distribution to customers, and includes slave devices for performing switching functions. The gateway provides remote access to the slave devices and the LAN.

29. A method of interfacing a master application with a plurality of slave devices via a gateway using a nonaddressable protocol, comprising the steps of:
-
building a request at said gateway responsive to a first message received from said master application; transmitting said request to said slave devices; starting a timer having a timeout period; checking said slave devices for a second message within said timeout period; and building a response at said gateway responsive to said second message and transmitting said response to said master application if one of said slave devices provides said second message within said timeout period.

30. A method of interfacing a master application with a plurality of addressable slave devices via a gateway using an addressable protocol, comprising the steps of:
-
building a request having an address at said gateway responsive to a first message received from said master application; transmitting said request to one of said slave devices, said one of said slave devices having said address; checking said slave device at said address for a second message; and building a response at said gateway responsive to said second message and transmitting said response to said master application.
