Manage the OPC UA client
You can use an OPC UA client object to import objects and variables at design time or runtime from an OPC UA server.
At runtime, you can use the imported objects and variables to create application logic.
At design time, you can use the
FactoryTalk Optix Studio
editor to select nodes to be synchronized. During import, for each node selected on the server, a corresponding project node is created. If the client has adequate permissions (set in the User Identity
parameter of the OPC UA client), the nodes remain synchronized with the server nodes in reading and writing at runtime.
IMPORTANT:
For nodes imported at design time, including object/variable types, the corresponding
BaseObject
or BaseVariable
nodes are automatically created.To import the nodes at runtime, synchronize nodes:
- When the OPC UA client object is initialized.
- At the start of the project at runtime.
