The OPC UA Client Server driver combines both client and server functionalities within a single package. It isn't compatible with previous releases of either the OPC UA Client or OPC UA Server packages. Therefore, these previous packages must be uninstalled before installing the new driver.
The OPC UA client operation enables deviceWISE to establish connections with OPC UA servers and replicate their nodespace within a variable tree inside a device. Conversely, the OPC UA server operation enables a deviceWise device to be exposed through OPC UA, allowing it to serve as an OPC UA server accessible to other OPC UA clients.
Driver Upgrade Considerations
Before installing the OPC UA driver, ensure that the deviceWise core is updated to at least version 24.01. Remove all other OPC UA packages before installing the version 3 OPC UA Client Server package. The OPC UA V3 client device shares the same driver ID as the OPC UA client driver from the previous release.
Unlike the V1 structure, the OPC UA V3 variable tree structure does not include a root folder followed by objects. For backward compatibility, there's an option in the device edit screen called "Include Root Folder."
The allow list and XML files from the OPC UA V1 driver are no longer needed and not being used.
Assumptions
It is assumed that you have experience with the following:
- OPC-UA specification
- OPC-UA Client Server configuration software
- The Workbench
-
The OPC UA Server and OPC UA Client package are NOT installed in the Asset Gateway or Enterprise Gateway.
Before using information in this guide: should have occurred:
- An Asset Gateway or Enterprise Gateway product is installed in its operating environment
- The Workbench is installed on a computer that has TCP network connectivity to the node
- The servers that will be accessed by the OPC-UA Client Server driver have been configured and are accessible.
