How can we improve PI Connectors?

Support PI tag renaming

Tags created by a PI Connector can be renamed, but these renamed points can be "forgotten" if the Connector's point cache is lost. Updating the Tag Mapping configuration file can avoid this cache loss, but I would like to be able to rename Connector tags without updating this configuration file.

    Renaming tags for connectors would be really helpful. The tag name provided by the "source" is not always that intuitive. Eq for the IEC 60870-5-104 tha tagnames are a combo of the CA and IOA adress

    Although this is more specific to the BACnet connector, it still applies under here. Currently, if network changes are made that necessitate an IP address change, tags would have to be recreated, whereas with the interface, only changes to the instrumenttag would be needed to reflect the changes to the data source.

    If we could set a tag renaming mask using regular expressions it would be extremely helpful. This piece of functionality is a must before we can move to the OPC UA connector. This issue prevents us from using other connectors as well.

    Thanks @Diego and @Danny for your questions. We don't have a schedule yet for this item. We are in the process of researching how to best architect this underneath the hood. Our prototype is not in a sharable form so will have to show you once we get closer to beta. Recommend you vote on this item and be sure you are signed up for updates.

    Hello @Chris, a customer wants to know if this feature is planned to be integrated on PI Connector for Wonderware Historian. If so, may you give an idea of the timeline of the feature set please ?

    I have a customer who is upgrading from an OPC DA interface to an OPC UA connector. They have an existing tag naming convention, as well as many Excel spreadsheets and PI Datalink functions that already use tag names. They are considering moving to the OPC UA connector but will need a reliable and supported way of maintaining the existing tag names rather than using the connector naming convention.

    I have a case where I deliberately delete the Connector's point cache file so I can create new Point tags when I reconfigure my DAQ inputs. I would like to have a way to clear this cache other then finding the file on the drive with Windows Explorer and deleting it.

    I'd prefer not to have to do this but is the work around for another issue (with the Archive) where if I rename the Descriptor I can no longer query the old Descriptor. If I change the auto generated Point Name, I can continue to query the old Desciptor data. We are using the Historian for R&D so the Hardware configuration and thus the DAQ sensor configuration is constantly changing.

    I am EPM for an EA customer that is requesting this functionality. They plan to migrate OPC DA Servers to OPC UA Servers and would like to keep tag names. It would be great for them to have the option to allow OPC UA Connector to perform naming convention configuration so the OPC UA Connector sends data to tags (in the PI Data Archive) that do not match the name in the OPC UA Server. Renaming all the tags in the PI Data Archive will be very time-consuming not only at PI Data Archive level but also at client level (displays and reports)

    Being able change or remove the current default tag name prefix (<pi connector type>.<data source name>) through the Web UI would be really useful. We have applied the company standard tag naming convention in the OPC UA server, but then the PI Connector adds a prefix that can't be removed which spoils the tags in PI.

    This is highly important for companies with Tag Naming Convetion and having a miture of User which are using Process Books with Tags and Process Books with AF Attributes

  • Matt Geerling commented  ·   ·  Flag as inappropriate

    I think ideally you'd be able to change things like the tag naming prefix from the connector web UI rather than going into config files as well
