Configure values for Object data types

After you have set Value Type to one of the Object data types, you then define the attribute's value.

1. Click in the Default Value field.

   The action button beside the field changes according to the selected value type.

   Value Type	Action
   <Anything>	While allowed, the Anything value type is not recommended. Note: When the value type is unspecified, many client applications may have difficulty working with that attribute. For example, PI OLEDB Enterprise and AVEVA PI Vision would all have reduced capability with such attributes, such as the inability to trend a value numerically. Furthermore, standard PI AF features such as automatic UOM conversion, Formulas, and Analytics cannot function with attributes that have no value type.
   Attribute	Click to open the Attribute Search window. Enter search criteria, as described in Search for attributes on elements.
   Element	Click to open the Element Browser window, where you can locate and select an element.
   File	Click and select Upload. Locate and select a file in the Open window. For acceptable types of attachment files, see /FileExtensions in AFDiag utility parameters. Caution: Before you upload a file, run an anti-virus check and ensure that the file size does not exceed your storage space. Some file types can pose a security risk, and a warning message will be displayed, asking if you are sure you want to continue. The list of file types that PI System Explorer considers unsafe can change. As a guideline, look at Microsoft's list of file types blocked by Outlook.

2. Click OK.

   When you check in your changes, PI System Explorer sends the resulting value to PI AF.
