OPC-UA Protocol Adapter Release Notes 24.07.0

Enhancements

This release contains the following enhancements.

OPC-UA Data Quality Status

When OPC-UA data quality status is processed, bad or uncertain data will be forwarded as a null value with the quality flag set to "0" to Time Series.

Polling Mode

Polling mode may now limit the number of nodeID objects per message request. Add this number to "max_operations_per_service_call" in the options block. (The default is "0", which means no limit and the total count of nodeID objects will be put into a single read polling request.)

NodeID Specification

NodeID specification in opaque or binary mode is now supported. For example:

• ns=2; g=<UUID>; or
• nss=2; g=<Base64 string>

Alpine Base Image

Updated the Alpine base to v3.20 from 3.14 to fix security and stability issues through component upgrades.

General Improvements

Various internal stability and performance fixes.

Bug Fixes

The following bug fixes were implemented in this release.

Subscription Mode Halting

Fixed a condition where subscription mode could halt when repeated nodeID subscription requests failed.
