| RequireValidAuthenticationToken | Enforce that the server provides a valid authentication token. |
| RequireValidServerNonce | Enforce that the server provides a valid server nonce. |
| RetrialDelay | A delay before the component will try to reconnect the session, if it failed to connect it previously, or a serious failure occurred related to the session (in milliseconds). |
| SanitizeReferenceDescriptions | Sanitize the reference descriptions (from browsing). |
| ServerShutdownRetrialDelay | Retrial delay after server shutdown (in milliseconds). |
| SessionConnectTimeout | A session connect timeout (in milliseconds). |
| SessionTimeout | A session timeout (in milliseconds). |

| StandardName | A symbolic name of the current parameter combination if it has a standard name. Empty otherwise. |
| StatusSubscriptionSamplingInterval | The sampling interval the client uses when subscribing to server status information (in milliseconds). |
| UpdateEndpointBeforeConnect | Determines whether to update the endpoint description with information from the server's discovery endpoint before the session is connected. |
| UserIdentity | Specifies user's identity, using one or more user token infos, such as anonymous, user name, Kerberos, or X.509 certificate tokens. |
| WriteNarrowestIntegerType | When writing to nodes of OPC UA data type Integer or UInteger and the type is not given explicitly, use the narrowest type available. |
| WriteNarrowestRealType | When writing to nodes of OPC UA data type Number and the type is not given explicitly, use the narrowest type available. |
