  1. Apply the Connector Relay to IEC 60870-5-104 Connector

    Adding the Relay and the DCM framework to the "legacy"IEC 104 Connector in order to improve the architecture management and security

  2. Ability for PI Connectors to create future data point

    Add the ability for PI Connectors to create future data point. This is especially useful for the PI Connector for UFL. The current workaround is to manually create the point as a StoredValues=FutureData.

  3. UFL Timezone Conversion

    Supported timestamps are currently limited to Local or UTC timezones.

    Data sources may not be configurable to provide timestamps in supported formats.

    There currently exists no robust or simple way of converting between timezones using the UFL syntax or configuration.  Including custom daylight savings time logic in ini files for this is not a maintainable solution. DST rules change over time and vary from region to region.

    With the current limitations I am currently having to maintain more than 20 ini files with custom DST logic for our global operations.

    Including functionality to accommodate for the timezone formatting limitations of…

  4. 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.

    We are evaluating this proposal. If this request is for a specific distribution of Linux, kindly forward that information to me or please leave a comment with the device type/name or Linux distribution name.

    Description is currently supported only for PI Tags and AF Elements from version 1.3.×.×. However, description cannot currently be set at an attribute level.

  6. Allow the connector to use a proxy for web requests

    Provide a way to configure the connector to use a proxy and authenticate with the proxy if required.

  7. Support Assigning Point Sources for Connectors

    Connectors currently assign point sources; this is not user configurable.  In addition, all connector of like kind get the same point source.  This makes it difficult to determine which tags "belong" to which connector node.  Users would like to be able to monitor\count\filter searches based on connector node.

  8. PI Connector for IEC 60870-5-104 bi-directional between SCADA and PI

    RWE Power AG

    “But one really important feature we need, is the ability to write back from PI into the SCADA system
    Until now, we couldn’t find anything about this (important) functionality.
    So our question is if we can use this connector bi-directional?
    And if not, is this already in the roadmap for this connector?”

    Can you share with us any info about your use case for sending data back to the SCADA system? For example, what is the purpose of that data? How many tags and how often will you send?

  9. 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,

  10. Control which PI/AF servers each data source sends data to.

    Right now, for one instance of the connector, all configured data sources will send data to all configured PI Data Archives and PI AF Servers. It is all or nothing. Due to the fact that you cannot have multiple instances of the same connector on any given node at a time, if you want this kind of granular control you would need an entirely new node and another connector. In the past, it was trivial to have multiple interfaces instances on the same node to send different data to different PI Data Archives; connectors should allow this capability.

  11. Do not synchronize description from OPC UA server into PI Tag

    There are situations when customer prefers to use “description” in PI Tag attribute that is independent from item “description” provided by OPC UA Server.  
    Currently, during each synchronization, the OPC UA Connector synchronizes descriptor from OPC UA to PI Tag and overwrites desired “Descriptor” attribute provided by customer. 
    Although the solution would be to have desired description already on the OPC UA Server, in some situations (OPC Server managed by 3rd party) it is not possible. It would be good to have configurable parameter in OPC UA Connector, which disables synchronization of item description from OPC UA Server to PI tag.

  12. Make the UFL Connector logic development/testing/debugging process less tedious

    Deploying a UFL Connector solution requires a LOT of edits of the INI file as part of the development/testing/debugging process. After each INI file change and file save, the required procedure is as follows:
    1. Click on the Data Source List link.
    2. Click on ‘See Configuration’.
    3. Click on the ‘Change’ button.
    4. Click on the ‘Browse…’ button.
    5. Double-click on the INI file.
    6. Scroll the page down until the ‘Save’ button is visible (I’m using a 1920 x 1080 monitor).
    7. Press the ‘Save’ button.
    8. Click on the ‘Overview’ link.
    9. Press the ‘Start connector’ button.

  13. PI Connector Relay support write modes

    While writing data to PI through the connector relay there seems to be no option to control the write mode . E.g."[-109] Value at This Time Already Exists" is shown in the logs if the archive already contains an event with the same timestamp. The default update option can be "Replace" instead of NoReplace. Other write options can be made configurable.

  14. Add the ability to select a subset of PI Points from a PI Data Archive

    The PI System Connector allows to include PI Point replication directly from the PI Data Archive even if they are not reference in the PI AF hierarchy with the "Include all PI points from this PI Data Archive" option.

    I would like to replicate only some PI Points that are not referenced, not all. This would remove the need to maintain both a PI to PI and a PI System Connector.

    I could create a bogus AF Database referencing those points but I would prefer not to.

    We are currently researching expanded flexibility of data selection for PI System Connector.

    If you haven’t already shared your use case in the comments, please do so or feel free to email me. Your comments are extremely valuable to us as we are selecting the best solution for this functionality.

  15. Option to remove/edit template prefix

    Allow for connectors to create templates without the fixed prefix. E.g. The option to name an AF template "templatename" and not "UFL.templatename"

  16. Prevent OPC UA Connector 2.x from doing Data Discovery in Tags-Only mode

    Use case: If we are frequently adding OPC UA tags and OPC UA server has a large variable count, then each discovery will increase the amount of time for it to complete. This increases the amount of time needed to discover the data source + configure new tags, and can also exhaust machine resources during the discovery.

    In version 1.3 of the connector, tags-only mode did not do a discovery.

  17. 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…

  19. Enable setting tag attributes in UFL Connector

    UFL Connector should have ways to set tag attributes. There should be way to set the default compression and exception settings and also other tag attributes like point and data security.

  20. 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.
