Prior to UniInt v4.6.0.60, UFO sync files created during interface startup would inherit file permissions from their parent folder (assuming child inheritance had been enabled on the folder).

With UniInt v4.6.0.60, this behavior changed and now sync files created by the interface do not respect inheritance.  Instead, they are created with a standard ACL containing only the local "Administrators" and "Users" security groups.

For users with complex file permission schemas, this change introduces additional, unnecessary configuration efforts that scale as interface numbers grow beyond the site-level. 

Currently (as of PI to PI Interface AutoPointSync Connector Version 1.5.0.7), it's not possible to sync changes to "Point type". (See pg 5 of user manual).

Please make this possible in a future release.

We noticed that changes to the configuration of newer interfaces / connectors like
- PI EMDVBCS interface 4.0
- PI inbatch interface
- PI Connector Wonderware Historian
are no longer recorded in the PI Audit trail. (see also TechSupport Case # 937205)
This is a compliance issue for the regulated industries.

SNMP Interface should support using multiple types of encryption such as DES, 3DES, and AES-128 bit, AES-192 bit, and AES-256 bit.

Add a watchdog counter or something similar into the shared memory header. If the counter fails to update, initiate UFO.

If PIBufSS crashes, data loss can occur.  implement something that allows UniInt to know that the Buffer Subsystem is not responding and initiate failover if available.

This was previously enhancement 119481.

Regulatory and/or security requirement to separate data collection from data storage using a one-way data flow. Could apply to Interfaces or Connectors, for example PI Interface for Emerson Ovation.
PI Interface/Connector -> one-way data flow -> PI Server/EDS/OCS

When primary server is down, secondary server is accessed instead of primary server, which is good. However, in the case of output point with source tag, it stops working, then restarting the interface instance of interest is needed. Of course, if we set up UniInt Failover that backup instance keeps its session with secondary server, this issue can be prevented. But, it will be better if source tag is also switched to secondary server.

Currently, the device status is updated on startup, on change, on shutdown, and on each performance summary interval.

However, for a device status tag created while the interface is running in a good state, the device status tag will remain at 'Pt Created' and not update until the interface status changes or the interface is restarted.

A newly created device status tag should display the current state of the interface without needing a status change. This is especially helpful in cases where the interface cannot be restarted for the tag to pick up a status update.

Allow for monthly scan intervals for scan classes. i.e. "scan monthly on the first hour of the first day of every month".

It can reduce the chance of startup failure because of the connection to PI Data Archive time-out. It's also helpful if interface can reduce time to get PI point information from PI Data Archive.

1. Having the capability of acknowledging the message in the PI Buffer GUI and removing the "red flag" when messages acknoledged.


2. Having the Buffer updated automatically when a tag is renamed, without having to restart the buffer.

When an interface fails writing to a DCS system, the interface writes a failure status to the output tag and goes on.  User has requested an option to have an output tag retry after write failure. It would be good to have this functionality in all uniint interfaces as they are recompiled, starting with the OPC DA interface, also to have this added to PI Connectors. Retries could stop after x retries of 1 minute retries, or when a new output value comes in. Or some other policy could be worked out.

Provide a configuration option in UniInt interfaces, to enable shutdown of the interface if it consistently receives error messages when attempting to write to PI. Recently had an interface successfully connect to PI but not achieve write access to its tags; would've been nice to have this interface gracefully shut down or restart, and allow its UFO failover partner to serve the data flow

I understand that you can remotely view logs using pigetmsg. However this solution does not work for me as the interface is on a controlled network that only allows outbound traffic. I would like a way for the interface node to be able to push out interface logs somewhere such as to my DA, that way I could use SMT to view my interface logs.

As a PI System Administrator, I would like to monitor the point count and other parameters for scan class 0 via Performance Counters. Currently, this is only exposed via the UniInt Health Tags.
