ProtoLink developed a Microsoft Windows application that allows energy industry
professionals to monitor and control well pumping operations remotely from a
desktop computer. The program retrieves live data from remote telemetry
units (RTUs) via DDE servers. This information is then graphed in a
format specified by the user. Graphs may be printed and stored in files
adhering to an industry standard. Unlike previously available dynagraph
display applications, this program supports multiple industrial
protocols. Dynagraph setpoint editing may be accomplished by dragging a
setpoint bitmap with a mouse. The program offers features expected in a
graphing package, including automatic scaling, line type and color selection,
legends, grid lines, etc.
