UniInt should include a test mode for all interfaces that collects data but does not send it to PI.
This functionality would allow users to test the connection to the data source and inspect the data that is retrieved without sending it to PI. That data might be written to a text file, for example.
This would allow users to verify settings and data integrity without needing to delete archived values, for example. Potentially, this functionality would also have some type of PI point selection so that user would be able to select which tags the interface should use for this test mode, rather than using all tags (The interface would essentially assume that all other tags have scan off).
