6. Data Logging Functions
6.1. General
The Dupline Mastergenerator can be configured to log Digital signals, Analink signals, Multiplexed analog sig-
nals and Counter values. The loggings can either be event or time based. Logged values are always stored in
non-volatile memory to enable later retrieval. Simultaneously, at the actual time of logging, the values can be
sent to the Central Dupline-Online Database via GSM modem or the Internet. The Dupline-Online WebServer
then makes it possible for users with individual passwords to access own real-time and historical Dupline data
via the Internet.
6.2. Dupline-Online
Dupline-Online is a new Internet based concept for central and de-central monitoring and control of remote
facilities such as water works, power stations, apartment buildings, super markets, gas stations, car wash
machines, elevators and unmanned railway stations. As the interface to the physical layer, the Dupline
Fieldbus collects and controls all desired field data such as energy, water and gas consumption, alarms, light-
ing, pumps, movement detectors, temperature, humidity, pressure, fluid levels etc. The Dupline
Mastergenerator can be programmed to log any combination of digital, analogue and counter signals based
on events or time and send them to the central Dupline-Online Database via the built-in GSM Modem (option-
al) or via the Internet. Users can then access own real-time and historical data on their existing internet-
connected IT-equipment by entering username and password on the homepage www.dupline-online.com.
Dupline-Online services include alarm buffers with time and date tags on all events, trend curves for
analogue signals, histograms with daily energy consumption, export of data to other systems, SMS alarms to
mobile phones and buttons for switching signals at the remote site.
