OPC UA Connector Trend Advise Option
OPC UA Connector Trend Advise Option, such as in the UniInt interfaces
Gabriel Verreault commented
There should be a way to better handle infrequently changing values, but Trend Advise should not be the implementation. Trend Advise is the same as changing the PI Point to STEP=ON. Trend Advise stores a value that would not have been actually read from the OPC UA Server and stores the last value right before - this does not only occur when there is a long period of time with no data, it happens for every event, meaning that in practical terms, it becomes a step tag.

This is a must have for industries where trending is important, especially for CBM.

This should be default behavior on all streaming functions.
