Owning Palette: OPC UA Server VIs

Requires: OPC UA Toolkit

Stops an OPC UA server and disconnects all OPC UA clients. When you stop an OPC UA server, you still keep all the folders, items, and properties. Use the Start VI to restart the OPC UA server.

When you use the Stop VI to stop an OPC UA server, if the OPC UA server is connected to any OPC UA client, the OPC UA server goes into a shutdown state and stays for three seconds. During this time, the OPC UA server does not accept any new connections. However, the connected OPC UA client can perform tasks, such as disconnect from the OPC UA server, release resources, and so on.

Example

OPC UA server refnum in specifies the reference data value of the OPC UA server.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
OPC UA server refnum out returns the reference data value of the OPC UA server.
error out contains error information. This output provides standard error out functionality.

Example

Refer to the OPC UA Demo.lvproj in the labview\examples\Data Communication\OPCUA directory for an example of using the Stop VI.
