Station: Name of the station that the VV belongs to.
Station ID: ID of the station the VDV belongs to (do not change).
Variable: The name of the variable.Time Variable options
Time Variable: 0 means it is not a Time Variable, and 1 means it is a Time Variable.
Starting From: Time Stamp from when the equation should be active (only for Time Variables).
