How can we improve PI Connectors?

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.

    If I understand this correctly, the solution provided by PI Connector for OPC UA version 1.3.x requires you to maintain a csv file with all your opc server tags. That is impossible when your opc server have over +100K tags.

    This functionality is available in the PI Connector for OPC UA version 1.3.x - available on the Tech Support website. Look for DataChangeTrigger in the User Guide. It explains how to set a subset of tags to update everytime the timestamp updates. In conjunction with SamplingInterval, you can define the data retrieval rate, and when is the data going to be sent to PI.

    This functionality is necessary for Industry, we had it using one concurrent product, I hope you will implement it asap.

    Since it also has to do with unchanged data updates, allow "exception reporting" capabilities where a tag can mimic trend-like behaviors, which are useful for things such as Set Points.
