    PI System Connector with configurable snapshot support is coming soon! In order to provide you with the latest and most secure PI Connector, the timeframe for this release is being extended to May. Be assured that we are working diligently to provide you with much anticipated features as quickly as possible.

  2. Connector-level Failover - OPC UA 2.x

    Support connector-level failover in PI Connector for OPC UA 2.x (relay-enabled version). Similar to UniInt failover (interfaces), failover should be data source specific and always favor the data source in the better state.

  3. Develop an interactive INI editor for the UFL Connector

    The editor should allow you to see in real time how it interacts with the data. Being able to test the INI file prior to loading some file would make it much more manageable to read a variety of data format and insure that it has the expected behavior before starting the connector and having to use a trial and error approach. A good example of this is what Microsoft does with PowerQuery in PowerBI. This would allow troubleshooting UFL issues much more easily and allow more people to use the connector without having to spend a serious amount of…

  4. 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.

    EVALUATING  ·  Abbas Saboowala responded

    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.

  5. PI OPC UA Connector Array support

    Add reading capability for OPC UA Arrays. Currently items with “ValueRank“ = 1 are ignored.

  6. Connector Failover

    Add failover capability so I can run a pair of connectors that will failover to the backup if the active is unavailable

  7. Allow restarting on a data source basis instead of having to restart the connector

    Example 1 - OPC
    If a new connection needs to be made to one OPC Server, restarting the connector forces all data sources (and potentially connections to multiple OPC Servers) to be restarted.

    Example 2 - UFL
    If my web service is down and I do not want to connector to keep trying to access to REST Server, I cannot stop/disable only one data source

  8. 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.

  10. Support HTTP Token Authentication to a REST Endpoint

    The REST endpoint from which I want to pull data requires token authentication. I would like the UFL Connector to be able to obtain the token given the username and password I enter on the Admin page.

  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. 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.

  13. PI Connector for IEC 60870-5-104 writes 'No Data' or another SYSTEM digital state when connection to the Data Source is lost.

    This connector is specially used to monitor the connection of the machines, but if there is a general network crash, and the connector losses the connection to the Datasource, it will stop sending data instead of sending something to alert of the situation.
    Not being aware of that situation can cause big impact in the companies.
    Receiving a Sytem digital state when the connection to the data source is lost would help to create an alarm and let the people in charge know.

  14. 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.

  15. PI System Connector should be able to delete values on the destination server if they are deleted on the source server

    Sometimes when performing analysis recalculations, values are dropped from when they were initially recalculated. For example, when an analysis runs initially, it may calculate 15 values, which are then written to the source and transferred over to the destination as expected. However, if I perform a recalculation where I choose to permanently delete existing values and recalculate due to some of the analysis inputs having changed, and only 10 values are now written to the source server, these values are written to the destination, but the existing values that are now "incorrect" are still present. I would like for the…

  16. OPC UA: Set PI Tag Zero and Span Based on OPC UA Range

    For OPC UA Analog Items, the OPC UA standard mandates an EURange property and an optional InstrumentRange property. These Range properties contain a Low and High field.The PI Connector for OPC UA should have an option to use either of these Ranges to set the Zero and Span of the PI tags it creates and the Maximum and Minimum AF Attribute Traits.

  17. 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…

  18. 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.

  20. 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 have started development to include the ability to specify a query that will define which PI Points are included in the data sent from the source to the destination using PI System Connector. We look forward to sharing more with you about this release in early 2021.
