OPC UA Client Application Operations in OpcCmd
From OPC Labs Knowledge Base
Example:
If you execute the commands listed in the example below, you will get an overview of available client operations.
- 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-?,-hor--help(possibly preceded by the command name) at any time to obtain help for this prompt (or its commands). registerToGds opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer -eu appadmin:demo(registerToGdscan be shortened tortg).findGdsRegistrations opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer -eu appadmin:demo(findGdsRegistrationscan be shortened tofgr).

- You can check the parameters of the client instance certificate by entering
getInstanceCertificate, or shortened:gic. - 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.
