OT Source: Source of Tags and Tag Value from the Edge
The following table provides a list and description of the fields that exist in the OT Source family and are available on the baseline OT Source datasheet. The information in the table reflects the baseline state and behavior of these fields. If your implementation has been customized, these fields may behave differently, and fields in addition to those listed here may be available.
This family is enabled for site filtering, which means that records in this family can be assigned to a specific site and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. For more information, refer to the Site Filtering section of the documentation.
