MemberDescription
SwingingDoorSwinging door (rate) deadband. A "swinging door" deadband is the percentage of deviation in the full-scale value range for an analog tag. The swinging door (rate) deadband applies to delta storage only. Time and/or value deadbands can be used in addition to the swinging door deadband. Any value greter than 0 can be used for the deadband. A value of 0 indicates that a swinging door deadband will not be applied. The swinging door deadband is essentially a rate of change deadband, based on changes in the slope of the incoming data values.
TimeValueValue and/or time deadband. The minimum time, in milliseconds, between stored values for a single tag or the percentage of the difference between the minimum and the maximum engineering units for the tag. Any value changes that occur within the time deadband or any data values that change less than the specified deadband are not stored. The time deadband applies to delta storage only.

Example
