Here are some typical applications of DeltaV OPC UA servers and clients:
- OPC UA server in the PK controller serves real-time module data to an
OPC UA client, typically third-party historian or a local HMI panel.
- Workstation OPC UA server provides real-time data,
historical data and alarms event data to any OPC client that consumes that
information. Typical examples include enterprise historians and any MES layer
applications. It basically replaces OPC Classic servers.
- EIOC OPC UA client reads and writes from a third-party
OPC UA servers. The servers can be on the MES layer or on a plant LAN (for
example, PLCs).
- Workstation OPC UA client reads and writes real-time
data from a third-party OPC UA server. Typically, this is used to replace OPC
Mirror applications that connect to servers in the MES layer.
