Hello,
I am beginner in the OPC UA world.
Are there builtin nodes for physical units like Volt, Pascal, metre, ...?
If there were none, how can I express a physical unit, maybe as a string like "m/s2"?
Thanks

Hi,
The AnalogItemType in OPC UA defines a Property EngineeringUnits with the DataType EUInformation. This DataType contains a display name e.g. 'm/s2' but also a UnitId that can be processed by algorithms. The UnitIds are defines in OPC UA Part 8 - Data Access

Hi UA Support Team,
Thanks for the answer.
I now have a good understanding about EngineeringUnits.
