Instrument Type Catalog

An "instrument type" consists of the association of an instrument function with a class. For further information, refer to Class Definitions. A description for the type may be entered, and an I/O type and location specified.

When a new instrument is created, a class is specified. This in turn determines which tag formats may be selected for the instrument, and if the selected tag format includes the instrument function, which functions may be selected.

To open the Instrument Type Catalog, select Setup > Type Catalog from the Project tab. The Instrument Types Catalog window is then displayed:

Note: By default, the Instrument Types Catalog window is displayed when the above option is selected. To open the Loop Type Catalog window, select Loops from the Catalog for list. Select Instruments from the Catalog for list to open the Instrument Type Catalog window again.

These additional fields are also available in the windows used for creating and editing instrument types (see below).
