Enter and Configure Formula Parameters

A formula parameter is defined by first typing a name, typing an optional description, and selecting the data type. After the name, description and type are defined, parameter elements must be configured. This process includes creating and assigning tags to elements, defining the operator display and edit capabilities for each element, and if the parameter is a process variable, defining the default values.

Automatic Tag Creation and Assignment

Tags are created and assigned to the elements by selecting all appropriate check boxes for each element and clicking Create Tags. The created tagnames are listed in the tag assignment field.

When you attempt to delete tags, you must acknowledge a warning message.

Manual Tag Creation and Assignment

Tags can be manually created and assigned to the elements by selecting an element name check box and then clicking Assign Tags. You can then select tags from the Tag Selection dialog box. The selected tagname is listed in the tag assignment field. The tags available for selection from the Tag Selection dialog box consist of only process tags if you are configuring a process phase. If you are configuring a transfer phase, the list only includes transfer tags. The tags that are available for selection have the same data class as those assigned to the parameter. For example, the system tags as well as all defined string tags are available when you assign tags to a parameter with a string data class assignment.

Note: You cannot delete manually created tags. Only automatically created tags can be deleted.

Operator Display and Edit Configuration

Each element must be configured for operator display and editing. This is done by selecting the appropriate check box and clicking Apply.

Default Values for Process Parameters

Process parameters can be assigned default values by editing the appropriate fields and clicking Apply. The defaults are shown as default values when the phase is used in a recipe procedure.
