•DB1 %Fs – Deadband (% of full scale). If the value has changed less
than the deadband then it is not spontaneously transferred.
•DB2 %Fs – This is used instead of DB if the Crit.Min and Crit.Max
fields are used and the value falls within these limits. In case of offline
(GSM) channel, if the change in value is bigger than deadband 2 (% of
full scale) then a call to SCADA system is initiated.

Editing formulas
Formulas can be created between the values of analog and/or digital objects.
Referencing to object values
To use the measurement object in the formula, insert an @ sign together with
the object address up.
Example: @101 points to the value of the object with an address to uplink
101.
Constants
Constants can be used in formulas.
Example: 1.1+2.2+3 consists of 3 floating point constants
Brackets
Brackets can be used in formulas to change the priority of the operation.
