Attribute set table (PIATRSET)

The PIATRSET table contains sets of attributes used to build point classes. An attribute defines a point attribute; it is comprised of a name, data type and default value. An attribute set contains a list of attributes. Attribute sets are the building blocks of point classes. Point classes are made up of a list of attribute sets.

Note: Changing existing attribute sets - except for changing default values, should be done with great care, in standalone mode.

An attribute set has many of the “Attrib, Default, Type” triplet. The ellipsis (…) following “TYPE” indicates those three may be repeated.

The following piconfig session demonstrates how to list the attribute sets on the Data Archive server:

* (Ls - PIATRSET) PIconfig> @table piatrset
* (Ls - PIATRSET) PIconfig> @ostr set
* (Ls - PIATRSET) PIconfig> @ends
*PIConfig Err> Wild-card specs. missing, default to '*'.
alarmparam
base
classic
sqcalm_parameters
totals
* (Ls - PIATRSET) PIconfig>

To list the entire classic and then base attribute sets use the ellipsis to repeat the output.

Users familiar with classic PI Points will recognize all these attributes. These two attribute sets, Classic and Base, make up the classic point class.

* (Ls - PIATRSET) PIconfig> @table piatrset
* (Ls - PIATRSET) PIconfig> @ostr attrib, default, type
* (Ls - PIATRSET) PIconfig> @ostr ...
* (Ls - PIATRSET) PIconfig> @istr set
* (Ls - PIATRSET) PIconfig> classic
