  1. 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.

  2. Get data by polling

    Support acquiring data by polling the OPC UA server rather than subscription.

  3. Description

    The OPC UA connector automatically creates tag descriptions when new tags are loaded (tag only mode). This behaviour may not always be desired . In our example we want to change the descriptions to something more meaningful.

    It would be useful to be able to disable the auto creation of tag descriptions.
