PVXS (QSRV2) makes it difficult to manually wire EPICS IOC records into a rich PV Access data model, especially when you want grouped structures, consistent metadata (NTTable/NTEnum/NTNDArray), and secure access. This Skill solves that by showing how to configure QSRV2 so an IOC automatically serves PV Access representations of your records, including advanced group mappings and PVA links.
Ask your AI to configure a PVXS QSRV2-enabled IOC that serves a single PV group as an NTTable using dbLoadGroup() and then verifies access security and correct subscription update behavior.

You can expose EPICS IOC records as PV Access structures by configuring a PVXS QSRV2 server, which automatically serves single-PV mappings and grouped data models over the network without requiring a custom server implementation.
Grouping multiple EPICS records into an NTTable PV is best achieved using info(Q:group, ...) tags or dbLoadGroup() JSON syntax within your IOC, allowing composite structures with consistent metadata modeling.
Yes, you can control write permissions and update triggers for PV Access group structures using +trigger, +putorder, and +atomic semantics, defining exactly what triggers updates and the processing order for writable group PVs.
EPICS supports mirroring values to and from remote PV Access endpoints by configuring PVA input and output links, including proc and sevr options, for local record integration with remote clients.
You must enable QSRV2 and load all group definitions before calling iocInit() to ensure proper pvxsIoc.dbd registration and correct PV Access server initialization timing within the EPICS IOC shell.
You can apply access security to PVXS group PVs by configuring .acf-based access controls within your EPICS IOC environment, ensuring secure and authenticated client interactions with your served structures.
