Set a deadband interval

The deadband properties allow sampling variables with respect to their previous sampled value.
TIP: For more information about common deadband configurations, see Deadband interval configurations.
Prerequisites
  1. To set a deadband interval
  2. In
    Project view
    , select a data logger object.
  3. In
    Properties
    , set
    Default deadband mode
     to:
    • None
      . Samples the variable when the value of the variable changes by any amount.
    • Absolute
      . Samples the variable when the value of the variable changes by an amount equal to or greater than the absolute deadband value.
      TIP: For example, if the variable value is 3 and the deadband value is 1, the variable is sampled when variable value is 4 or greater.
    • Percent
      . Samples the variable when the value of the variable changes by an amount equal to or greater than the % deadband value.
      TIP: For example, if the variable value is 10 and the deadband value is 20, the variable is sampled when the variable value is 12 or greater.
  4. Set
    Default deadband value
    .
    For example, if the value is 5, the logger samples the variables whose values have had an absolute or percentage change of at least ± 5 with respect to the previous sampling.
