The UaClient_Discovery structure manages a UA Client side discovery functionality.
Discovery is a two-step approach. In the first step, the available servers are discovered and in the second step the selected server is asked for its available Endpoints, describing combinations of protocols and security settings available to connect to the server.
OpcUa_String UaClient_Discovery::AuditEntryId |
An identifier that identifies the client's security audit log entry associated with requests issued by this discovery structure.
OpcUa_UInt32 UaClient_Discovery::CallTimeout |
The timeout for service calls in milliseconds.
The default setting is 10 seconds.
OpcUa_Boolean UaClient_Discovery::Connected |
A flag indicating if a discovery service call is currently active.
OpcUa_UInt32 UaClient_Discovery::ConnectTimeout |
The timeout for the connect call in milliseconds.
The default value for the connect timeout is 5000 milliseconds.
OpcUa_UInt32 UaClient_Discovery::SecureChannelLifetime |
The lifetime of the SecureChannel in milliseconds before it gets renewed.
This is the time the key pair exchanged during secure channel establishment are valid. The stack starts the renew process that exchanges new key pairs after 75% of the lifetime. The default lifetime is one hour.
