Add a catalog unit

Although you can add custom units to the catalog, before doing so you should make sure the required unit is not already defined. Dimensions can have multiple valid names, so you should check under alternate dimension names before creating a new unit. For example, length and distance are different names for the same dimension, as are voltage and electric potential.

To add an engineering catalog unit:

1. In the Operations Control Management Console, expand a server group and then expand a server.

2. Expand Configuration Editor, expand System Configuration, and then expand Tag Configuration.

3. Right-click Engineering Units Catalog, and then click New Engineering Unit Catalog.... The New Catalog Unit dialog displays.

   

4. For the unit's Symbol, enter Formal and Basic values.

   If the Basic value is blank, it is automatically populated with the Formal value.

   The Basic value is displayed as the unit's symbol by default.

   Notes: Unit symbols are case-sensitive and unique.
   
   In many cases, the formal and basic symbols are identical. In some cases, such as when extended characters are part of the symbol, it is appropriate to use the formal field for those values.

   

5. Enter a Name to describe the unit.

6. Selecting Visible allows this unit to be used as a canonical unit when creating an engineering unit. See Add an engineering unit for more information.

7. Select the Dimension and unit System this unit is associated with. See Manage dimensions, unit systems, and catalog unit visibility for more information.

8. If the selected dimension does not already have a base unit defined for the selected unit system, select Base to define this new unit as the base unit. If the dimension already has a base unit defined, this box is disabled.

9. Select OK to save the unit.
