OPC UA Interoperability Testing with OpcCmd

This article is mainly for internal usage.

Session

CreateSession() over an insecure channel with UA TCP and SecurityPolicy =None

Example: uaClient read opc.tcp://opcua.demo-this.com:51210/UA/SampleServer 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 opc.tcp://opcua.demo-this.com:51210/UA/SampleServer i=2255 --EndpointSecurityPolicyDisplayName Basic128Rsa15

ActivateSession() with user identity = username/password

Example: uaClient read opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer i=2255 --EndpointUser appadmin:demo

ActivateSession() with user identity = anonymous

Example: uaClient read //opcua.demo-this.com:51210/UA/SampleServer i=2255 --EndpointAnonymous True

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.

Use CloseSession() to end session. If possible, verify that the following service calls to the session are rejected.

Example:

uaClient --!option AmbientOutput=[Boolean]True --ConnectionMonitoring

read opc.tcp://opcua.demo-this.com:51210/UA/SampleServer i=2255

Then, keep pressing Enter until the ambient disconnection events are displayed.

Create and use multiple sessions.

Example:

!option AmbientOutput [Boolean]True

uaClient --ConnectionMonitoring

getService uaClientConnectionControl lockConnection //opcua.demo-this.com:51210/UA/SampleServer

\uaClient --ConnectionMonitoring read //opcua.demo-this.com:51210/UA/SampleServer i=2255

CreateSession() with an application instance certificate

CreateSession() over a secure channel with HTTPS and SecurityPolicy =None.

ActivateSession() with user identity = X509 certificate

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Basic256Sha256

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Aes128-Sha256-RsaOaep

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Aes256-Sha256-RsaPss
