I have code connecting to the PI AF SDK using python, but I am having a hard time figuring out how to get the description for a tag. I get the following error:


"The PI Point attribute 'descriptor' was not found. The attribute must be loaded before attempting to get its value"


My code throwing the errors:


def create_taglist():

    tags = PIPoint.FindPIPoints(piServer, 'LS*RMS Current')

    taglist = {}

    for tag in tags:


        taglist[tag] = {

            'descriptor': tag.GetAttribute(PICommonPointAttributes.Descriptor)


    return taglist
