Do not synchronize description from OPC UA server into PI Tag
There are situations when customer prefers to use “description” in PI Tag attribute that is independent from item “description” provided by OPC UA Server.
Currently, during each synchronization, the OPC UA Connector synchronizes descriptor from OPC UA to PI Tag and overwrites desired “Descriptor” attribute provided by customer.
Although the solution would be to have desired description already on the OPC UA Server, in some situations (OPC Server managed by 3rd party) it is not possible. It would be good to have configurable parameter in OPC UA Connector, which disables synchronization of item description from OPC UA Server to PI tag.
We have a slightly different use case. It's fine to synchronise but we need the ability to turn it off after the connector has built the initial setup.
Our problem is when buying off the shelf equipment we have no control over how the vendors present the data. The built in OPC server to the equipment may not be configured in a way that is user friendly or even complete. We could of course resolve this by requesting customising of the source system but that leads to considerable increases in complexity and cost and some vendors are not prepared to entertain doing it! Therefore the ability to synchronise the initial build and then turn off the auto update and complete the build in PI would be really helpfull
