Beginning with PI Asset Framework (AF) 2016, the annotation feature is used by client applications such as AVEVA PI Vision, but can easily be used by administrators to make notes on the following objects:
-
Case
-
Element
-
Event frame
-
Model
-
Transfer
File attachments
Users can attach a single file to an annotation. By default, the following file types are allowed:
|
File type |
Allowed extension |
|---|---|
|
MS Office |
csv, docx, pdf, xlsx |
|
Text |
rtf, txt |
|
Image |
gif, jpeg, jpg, png, svg, tiff |
The maximum file size defaults to 10MB.
Administrators can use the PI AF Diagnostics utility (afdiag located in the \PIPC\AF folder) to specify the file types that can be attached to annotations (with the FileExtensions parameter), as well as the maximum file size (with the FileMaxLength parameter).
Security for annotations
A user needs to have a PI AF identity for which the Annotate permission (an) is enabled. For more information on access rights, see List of access permissions.
