DeltaV OPC UA servers

The table shows the types of data that DeltaV OPC UA servers can share with OPC UA clients.

DeltaV node type	Real-time module data	Historical data	Alarms and Events

PK controller	Yes	No	No

DeltaV OPC UA servers store data in an OPC UA-compliant address space. The DeltaV system populates the address space automatically. For example, the workstation address spaces contain:

Alarms and Events for the areas assigned to the workstation
Module data for modules in the areas assigned to the workstation
Continuous Historical data that is enabled for this workstation
Workstation diagnostic parameters
OPC UA-specific parameters

Note

DeltaV OPC UA servers do not support off-line nodesets.
