description | An electronic trip unit having a two-wire, asynchronous, serial communication accessory network that is connected to a number of unique digital and analog remote slave devices. The address for each slave device is set by its function so that the trip unit does not have to be programmed in the field each time an accessory is added to the system. The network is capable of two-way communication when requested by the electronic trip unit. Accessory network communication is controlled by a first microprocessor within the electronic trip unit or alternatively by a network interface gateway. The first microprocessor also controls overcurrent and instantaneous protection functions of the trip unit while a second microprocessor controls voltage based and metering functions. The second microprocessor also has the capability of communicating with a central control network. |
