A system and method is provided for simultaneous communications on Modbus and DNP 3.0 over Ethernet for an electronic power meter. The system incorporates one or more protocol wrappers to provide compatibility with both Modbus and DNP based applications. The system removes the appropriate wrappers and routes the incoming data packet to its destination. Additionally, the system also wraps outgoing response packets with the appropriate protocol wrapper based on the related data packet wrappers.

A system and method for providing an additional option function to existing functionality of a meter device configured for measuring parameters of energy is provided. The meter device is coupled with an option device for exchanging data between the meter and the option devices along at least one data path, including exchanging initialization data provided by the option device between the meter device and the option device, wherein the initialization data is useable by the meter device for configuring the meter device to be in condition to operate with the option device. The data exchanged between the meter device and the option devices are processed by at least one processor. Upon the coupling of the devices and the exchanging of the initialization data, the meter device is operated with the option device for adding the option function to existing functionality of the meter device.
摘要:
An intelligent electronic device (IED) for monitoring/measuring parameters of electrical services to a plurality of loads and receiving/transmitting information over communication networks is disclosed. The electrical services may be connected to the same or different AC services. The IED may be configured as a terminal or a server of an Intranet, LAN, WAN, or the Internet. In one application, these techniques are implemented in IEDs such as digital electrical power and energy meters.
