Derived Signals
In addition to the raw signal data directly pulled from the datasource, there are derived signals which take raw signals from the same datasource and transform them. These Derived Signals once created work like raw signals when setting up SCADA Elements.
In the dialog that opens:
- enter in the new signals name,
- select the transformation method,
- and if needed choose the raw signal from which to derive the new signal.
Transform Methods
On creation of a new derived signal you need to choose by which method to perform the transformation.
Override
When creating a datasource you can setup Signal Value Mappings which map the raw signal value to element status values (Pump, Valve, Pipe).
In some cases, the value mappings are different on a signal by signal basis.
