Table attributes

Each table has its own list of attributes, with one attribute designated the primary key. The primary key is unique and is the first attribute shown when you run the ?atr command. The ?atr command shows each attribute's name, data type, default value, and current value, if applicable. Each of the table attributes can be viewed, set, or modified.

For example, the following command shows the PI point attributes and their default values for a point of the classic point class. The D: indicates the default value of the attribute and the C: indicates the current value, if applicable.

* (Ls - PIPOINT) PICONFIG> @tabl pipoint,classic
* (Ls - PIPOINT,CLASSIC) PICONFIG> ?atr
*> ?atr
1 - tag String D: !#!#!# C:
2 - Newtag String D: C:
3 - archiving BYTE D: 1 C:
...

Note: If you try to create a point without specifying the tag name attribute, the name defaults to !#!#!#, which is invalid. Therefore, you must enter a different, valid name.
