The OPC UA Server is the extension that contains the protocol specific logic to communicate with clients that supports OPC UA specification.
Supported devices and communication interfaces
The OPC UA Server has been tested interacting with the following OPC UA clients:
- Unified Automation - UAExpert
- Kepware Quick Client
- deviseWISE OPC UA Client
Client must be on different deviceWISE node.
Limitations
deviceWISE OPC UA Client is not supported on the same node when using OPC UA Server
OPC UA Client and OPC UA Server share the OPC UA libraries and cannot they exist in the same node. The deviceWISE OPC UA Client must be installed on a different node in order to access the OPC UA Server.
Referencing integer bit items (Nested Bool) in the device variables is not supported
Many of the devices that are exposed by the OPC UA Server support referencing individual bits within a one-byte, two-byte, four-byte, or eight-bye integer. Currently individual bits are not exposed by the OPC UA Server. Only complete variable is exposed to clients. Care must be used when referencing individual bits as each bit referenced will require its own read / write request against the physical device where the integer resides.
