2.) SVG SCADA - Hot Water Temperature & Pump ON/OFF

This shows a real-time interactive SVG SCADA drawing of a building's heating hot water system. A field temperature transmitter is sending its data over the DSN to the temperature gauge in the SVG SCADA drawing. An ON/OFF button provides the ability for the SCADA operator to turn the pump on or off.
Sequence Of Operation:

Initially the hot water pump is shown as "OFF" at the button. As the operator, you can click the button to request the pump be turned "ON".

When the operator requests the pump ON action, the message "ON" is published via DSN. The SVG SCADA drawing subscribes to the data. When the message is received via DSN, the SVG SCADA changes the button status display from OFF(red) to ON(green). Also the pump's impeller symbol will then be rotating, and flow arrows will move along the hot water piping.

When the pump is ON (green), The data from the field-mounted temperature transmitter is published over the DSN every two(2) seconds. The SVG SCADA drawing subscribes to the data, and the dial of the temperature gauge moves to display the data.
