Support for Alarms & Conditions. This data type would be good candiate for storing into Event Frames. Tell us more about your use case in the comments, which source system you have that support A&C, and how you would select which A&C to collect/not collect. How would you like Event Frames built and named?65 votes
We are currently evaluating how to appropriately and effectively bring this functionality forward. We are working through details pertaining to implementation of this functionality.
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.
Support acquiring data by polling the OPC UA server rather than subscription.25 votes
This request is partially similar to the following request – https://feedback.osisoft.com/forums/555139-pi-connectors/suggestions/19611235-retrieve-data-even-it-s-not-changed-on-opc-server
This should be self-explanatory. I'd also suggest making Linux versions of all software available, but this Connector would be a great start.23 votes
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.
Get Description from the OPC UA Server into the AF attribute23 votes
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.
