OPC UA Client Application Operations in OpcCmd

Example:

If you execute the commands listed in the example below, you will get an overview of available client application operations.

1. At the OpcCmd> prompt, enter uaClient getService uaClientApplication, or shortened: uac gs uaca.
   The program responds with the name of the client application (""OPC Command-line Tool"), which will be used for registrations to GDS. If this is the first time the program is run, it also creates its self-signed client certificate.
   All following commands are entered at the uaClientApplication> prompt. You can enter -?, -h or --help (possibly preceded by the command name) at any time to obtain help for this prompt (or its commands).
2. registerToGds opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer -eu appadmin:demo (registerToGds can be shortened to rtg).
3. findGdsRegistrations opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer -eu appadmin:demo (findGdsRegistrations can be shortened to fgr).

removeInstanceCertificate

1. You can check the parameters of the client instance certificate by entering getInstanceCertificate, or shortened: gic.
2. If you want to force the application to generate a new self-signed client certificate, you can do so by entering removeInstanceCertificate, or shortened: ric. This might be useful e.g. for repeated testing against a GDS, if you have already received a client certificate from GDS (signed by a certificate authority), and want to revert to the initial state. At the next OPC UA operation, the application will generate a new self-signed certificate for itself, and use it for subsequent operations.
