Adds trusted OPC UA client certificates to an OPC UA server.

The OPC UA client uses the security settings in communication only when the OPC UA server trusts the OPC UA client. Otherwise, the OPC UA client can only communicate with an unsecured server. By default, the OPC UA server application that you create trusts the default OPC UA client certificate.

After you start an OPC UA server, you cannot add trusted client certificates until the OPC UA server stops. Use the Stop VI to stop an OPC UA server.

OPC UA server refnum in specifies the reference data value of the OPC UA server.
trusted client certificates specifies the file paths of the public keys that the OPC UA server trusts. You can specify a relative path or filename for trusted client certificates. If you specify a relative path, the path is relative to the caller VI or to the application directory. If you specify a filename, LabVIEW searches the certificate files only in the location where the caller VI resides or in the application directory.
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.
