1.5 System Overview
The NRG SymphoniePRO Data Logger is an advanced, internet-ready, low-power, microprocessor-controlled
data logging system specifically designed for conducting resource assessments for the renewable energy
industry. Each of the 16 or 26 standard channels’ averages, standard deviations, and other statistical values are
calculated from continuous 1 second data samples.
The SymphoniePRO logger has selectable statistical averaging intervals (1, 2, 5, 10, 15, 30, 60 minutes). One
second samples can be recorded by the logger allowing review of the sample-by-sample data for complex
scientific studies. Data intervals are time-stamped with the beginning time of each interval and are written to
the internal Flash memory. If an SD card is installed, the data will also be stored on the SD card.
Addition of an iPack allows flexible options for data transfer through remote MetLink connections or standard
email services. MetLink is a proprietary protocol optimized for NRG loggers and transfers data over multiple
types of communication interfaces. MetLink allows connections to be initiated from either direction (from the
logger or from SymphoniePRO Desktop Application), and the MetLink Monitor utility can be used to view the
status of active connections.
Various communications options are available to fit your application and location anywhere in the world.
Cellular iPackGPS units can be easily connected to the back of the SymphoniePRO logger to enable remote
communications via a cellular network. iPackACCESS can be used in conjunction with a BGAN M2M Satellite
module for satellite communications capability where cellular service is either unavailable or unreliable.
iPackACCESS can also be used to connect the SymphoniePRO logger directly to a SCADA system or local area
network (LAN), where real-time (i.e., 1 Hz) data can be polled via Modbus TCP.
