Configure values for Basic data types

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

1. Click in the Default Value field.

   The format of the field changes according to the value type. See PI AF data types.

2. Enter the attribute's value in the Default Value field.

   PI System Explorer resolves the data you enter and when you check in your changes, it sends the resulting value to PI AF. For example, for DateTime, it sends the resulting date and time.

Examples

If the value type is DateTime, you can type the time in any string format that is supported by PI AF (including PI Time formats) or the .NET DateTime object. Some examples of valid entries:

*-5d
May 12, 2009
07 06 2010 10:00:00 AM
09 14 2008 14:00:00

To create an attribute with a link as a value, select the value type String and enter the URL as the attribute value. Strings that are recognized as absolute URL paths will be displayed as a link. For example, strings starting with http://, ftp://, file:// and www. are recognized as links, whereas strings starting with C:\, and abc.com are not. In PI System Explorer, links appear underlined and have an associated tooltip.
