PI Manual Logger uses comments to capture operator comments as part of the manual data collection process. Comments can be entered for the tag value being collected, a tag group, and an entire tour.
During data entry, PI Manual Logger stores comments in the PI Manual Logger database. After the comments and values are sent to the targeted PI Data Archive, reports can be set up in Microsoft Excel (using PI DataLink or other PI client tools) to retrieve process values and the associated comment entries from PI Data Archive.
Comments are stored in either or both of these methods:
-
PI Annotations
-
Comment tags - PI string tags configured at the tag, tag group, and tour level
Note: All tags must be created in PI Data Archive prior to using them in PI Manual Logger, whether it is making a tag a part of the tour configuration, associating a tag as a limit, or associating a string tag as a comment tag. Read/write security permissions must be given to the tags in the tour, as well as to the comment tags. Tags used as limits only require read permissions, unless they are being collected as part of a tour configuration.
PI Annotations
All tag comments are stored in PI Annotations for the entered value. OSIsoft recommends you choose this method for tags, since you do not have to configure a special PI String tag to store the comment.
Comment tags
If you use comment tags, such as the comment tags in PI Manual Logger 1.x versions (before PI Annotations were supported), you can associate a PI String tag with a tag, a tag group, and a whole tour. Comment tags associated with tour tags have the same timestamp as the process value tag. Tour comments and tag group comments are not sent to PI Data Archive unless they are associated with a PI String tag through the Comment Tag association. Tour and tag group comment tags have the same timestamp as the Tour Run timestamp.
Note: If you configure a comment tag for a process value tag, the comment is stored in the comment tag, as well as PI Annotations associated with the entered value.
