  1. PI Connector for OPC UA Relay Support

    As a PI Admin relays allow for improved security of process-network-to-DMZ communication.  This will greatly aide in the PI Connector for OPC UA's deployment in production systems.

  2. Support Alarms and Conditions

    Support for Alarms & Conditions.  This data type would be good candiate for storing into Event Frames.  Tell us more about your use case in the comments, which source system you have that support A&C, and how you would select which A&C to collect/not collect.  How would you like Event Frames built and named?

  3. Retrieve data even it's not changed on OPC server

    Currently Connector configured to rertieve event on change and not based on a scan class like interfaces.The Connector suscribes to the changes, and when a change comes in to the server, the data will be sent to PI connector. We need option to retrieve the data every certain minutes even data is the same and is not changed on OPC server.

    We understand that for slow changing points, values might not change often and thus there is a need to collect values at certain time intervals as opposed to on change. However, scanning at frequent intervals leads to increased load on the server and thus can lead to performance degradation. We are discussing how best to solve this problem with PI Connector for OPC UA.

  4. OPC UA: allow historical data access

    allow historical data access with custom time ranges, like OPC HDA

    We have a feature in the upcoming 1.2 release of the connector that will allow you to collect data from OPC UA tags that do not have current values but do have history. We would poll these every 60 seconds (default) to find new data.

    Was that part of this request in any way? Can you describe in more detail what you would like as a feature that prompted you to vote for this time?

  5. Ability to change which PI tag the PI Connector for OPC UA writes to without having recreate new PI tags

    Currently, once PI tags are created by the PI Connector for OPC UA the connector uses the point ID for its mapping from the OPC UA server to the PI tags. Thus, if a configuration change occurs on your OPC UA server (i.e. NodeIDs change) the only way to map the newly named (with no change in the data stream) NodeID to a PI tag is to create a new PI tag instead of simply changing the configuration on a PI tag. As a PI system administrator, I want the ability to change a PI tag attribute (i.e. Extended Descriptor)…

  6. OPC UA: allow a host name override

    Allow a hostname override when connecting to the OPC UA endpoint.   We have some use cases where the URL returned by two independent OPC UA servers has the same name.  This prevents the Connector from connecting to the correct endpoint. Allow an IP address to be specified in the config, which would be used to connect instead of the URL hostname.

  7. Linux Version of PI OPC-UA Connector

    This should be self-explanatory.  I'd also suggest making Linux versions of all software available, but this Connector would be a great start.

  9. Support Server Level Failover

    To ensure that data continues to flow from the OPC UA server to PI Connector for OPC UA, the connector could be configured to switch to another OPC UA server under the same conditions as the OPC DA Interface

    In our experience the majority of OPC UA servers do not yet support this failover. Can you describe the servers that support this? Are they native servers built for OPC UA or are they wrappers over OPC DA servers?

  10. PI OPC UA Connector - point attribute based configuration

    We are just starting the first tests with PI OPC UA Interface. We notice that the classic method of tag configuration, known from the interface, is no longer possible. This is probably due to the connector concept.
    Unfortunately, this does not fit with our central approach of tag configuration. We urgently need a way to control the transfer of the data into the archive, as usual from the interfaces, via the point attributes.

    Since there is a tags-only mode - is there any hope that there will be an OPC connector mode so that the connector behaves more like an…

  11. Selecting a subset of items from the same OPC UA template

    When multiple OPC objects share the same template, you can only either select the entire template or not since only the template would be populating the filter file. In the example above, if one were to want to bring CC1001 in PI but not CC2001, then, they would need to be moved to a specific folder in the UA Server or change the template on the UA Server side. There should be a user-friendly way to perform more granular selection

  12. Write event when data source is offline

    As a PI admin I would like the OPC UA connector to write a value such as 'disconnected' when the data source is offline so that I know when the connector is unable to connect to the data source,

  15. Allow options to alter the way the connector handles different qualities (bad, questionable)

    At this time, the connector does not expose any way to alter the way data of different qualities (bad, good, questionable) is handled. The PI OPC Interface allows several different options with regards to “quality” such as "send only GOOD quality data", "Store Value Flagged Questionable", etc. Some customers will want to keep the quality (eg. Pharma, FDA), while others don't want to (eg. Oil industry). When storing quality is not important, storing BAD and ? is simply a hassle. I would like to have the same functionality as the PI OPCDA interface.

  16. Transformations and scaling

    Add the ability to configure PI points so that the PI Connector for OPC UA performs transformations and scaling on the values before being archived.

  17. Connector should rescan UA server, on a configureable basis, for new objects already defined in CSV file

    It would be helpful if the UA Connector could rescan the UA server for new objects that have already been selected in the AvailableTypeDefinitions file and add them to the server on a configurable frequency. We primarily use the UA Connector for our wireless implementation and constantly adding one of two types of field devices that are defined. This would decrease the amount of time in having to stop/start the connector or using the workaround of remaking and changing the CSV file every time a device is added in the field.

  19. Add Time Offset Option to OPC UA Connector

    Please add a time offset option to the OPC UA Connector, similar to the old OPC DA interface (see attached screenshot).

    In come cases the OPC UA server may not actually be sending timestamps that are in UTC (ex. in local time) so an offset is needed to change the timestamps into UTC.

  20. Naming of the Data Access Filter File when exporting the available Type Definitions

    Currently, the filename will always be AvailableTypeDefinitions.csv. The filename should contain at a minimum the data source name.

    For example: <DataSource>_<DateTime>_AvailableTypeDefinitions.csv
