Details on AC configuration

CAUTION:

These datapoint types must only be changed using the configuration panels described before, otherwise inconsistencies will arise!

Internal datapoint _AcStructure

The parameters of the AC type compressions are saved in an internal datapoint of type _AcStructure. The datapoint elements have the following meaning:

Table: Meaning of the datapoint elements


Element name	Type	Meaning
general.intervals	dyn_int	all predefined intervals in the seconds format.
types.actype	dyn_bool	TRUE if the datapoint type was created with the compression configuration panel.
types.applied	dyn_bool	TRUE if the parameters of the datapoint type have been assigned to all datapoints.
types.archives	dyn_string	Name of the archive used
types.exceptions	dyn_ string	List of the datapoints that are not meant to assume the parameter settings.
types.functions	dyn_ string	The statistical functions set at the compression levels.
types.intervals	dyn_ int	The time interval of the compression levels in seconds.
types.names	dyn_ string	Name of the datapoint type created in the compression configuration.
types.sources	dyn_ string	Source for the statistical function.
types.vartypes	dyn_ int	0 = digital / 1 = analog.

All datapoint leaves of the node "types" have the same number of elements; each AC type has a line in the dyn fields.

Structure of the AC datapoint types

The datapoint types created in these configuration panels (AC types) have a permanently defined structure containing fixed structure elements and variable structure elements defined by the configuration.


Layer 1	Layer 2	Layer 3
AcType
	value
	C1
		MIN
		MAX
		...
	C2	MIN
		MAX
		....
	....

.value always exists. This element takes the source values.

.C1.MIN, for example, contains the statistical function Minimum for compression level 1. The name of the end leaves is always the same as the statistical functions used. Level 1 (C1) uses either the leaf .value as source or has the pseudo-function "MAN" (manual input). Level 3 uses the values from level 1 or 2 for its source.

For manual input, the value is set manually via the Laboratory Values panel (see Laboratory values panel).
