Value	Meaning	Description
0	Non-specific	There is no specific reason why the value is UNCERTAIN.
1	Last usable value	The connection to the data source is still established, however, the data source stopped updating the value for some reason.
2	Substitute value	A predefined value is used in case of an invalid value due to communication issues with the data source or a range violation. The reason for providing substitute values is configurable.
3	Initial value	A predefined value intended for the startup of the HMI system (or a sub-ordinate device) is used while not being able to provide values from the data source.
5	Range violation	The value lies outside the range defined by minimum value and maximum value. The limits define which direction (min or max) has been exceeded.
6	Sub-normal	A value derived from multiple values has less than the required number of good sources. This includes data aggregation by means of data compression algorithms.
