Defines how value changes shall be classified as part of the 'deadband' or the 'liveband'. A value which is within (less or equals to) the deadband value is part of the 'deadband'; otherwise it is part of the 'liveband'. Only values part of the 'liveband' are reported when using monitored items within subscriptions.
C#
public enum OpcDeadbandType
Name | Value | Description |
---|---|---|
None | 0 | There is no 'band'-logic to be applied to value changes. This means that every value change is part of the 'liveband' and is therefore reported using subscriptions. |
Absolute | 1 | The limit of the 'band'-logic is defined using an absolute value. Only value changes exceeding the absolute value of the deadband value are reported using subscriptions. |
Percent | 2 | The limit of the 'band'-logic is defined using a percent deviation from the default value range of a variable node. This option is only supported in case there a node provides range information. Only value changes exceeding the deadband value (which then expresses the percental deviation) are reported using subscriptions. |
