OPC UA Interoperability Testing with OpcCmd
From OPC Labs Knowledge Base
This article is mainly for internal usage.
Test preparation - example:
!variable set endpoint opc.tcp://opcua.demo-this.com:51210/UA/SampleServer
Session
- CreateSession() over an insecure channel with UA TCP and SecurityPolicy =None
- Example:
uaClient read %(endpoint) i=2255 --EndpointAllowedMessagedSecurity SecurityNone
- CreateSession() over a secure channel with UA TCP and SecurityPolicy=Basic128Rsa15 where the key length is minimum 2048.
- Example:
uaClient read %(endpoint) i=2255 --EndpointSecurityPolicyDisplayName Basic128Rsa15
- ActivateSession() with user identity = username/password
- Example:

- However, the anonymous identity is the default, and as such is used in other tests unless other identity is explicitly specified.
- ActivateSession - change user in an existing session.
- Not supported (by API).
- Use CloseSession() to end session. If possible, verify that the following service calls to the session are rejected.
- Example:
