    Properties

    channelSecured: [
        channel: ServerSecureChannelLayer,
        endpoint: OPCUAServerEndPoint,
    ]

    event raised when a secure channel has completed the OpenSecureChannel handshake. At this point securityPolicy, securityMode, and clientCertificate are available.

    closeChannel: [channel: ServerSecureChannelLayer, endpoint: OPCUAServerEndPoint]

    event raised when a secure channel is closed

    connectionRefused: [socketData: ISocketData, endpoint: OPCUAServerEndPoint]

    event raised when the server refused a TCP connection from a client (for instance because too many connections)

    create_session: [session: ServerSession]

    event raised when a new session is created

    event: [eventData: unknown]

    event raised after the server has raised an OPCUA event toward a client

    newChannel: [channel: ServerSecureChannelLayer, endpoint: OPCUAServerEndPoint]

    event raised when a new secure channel transport is initialized (HEL/ACK complete). Note: securityPolicy and securityMode are NOT yet established at this point. Use "channelSecured" for post-handshake notifications.

    openSecureChannelFailure: [
        socketData: ISocketData,
        channelData: IChannelData,
        endpoint: OPCUAServerEndPoint,
    ]

    event raised when an OpenSecureChannel has failed, e.g. invalid certificate or malformed message

    post_initialize

    post_initialize: []

    event raised after the server address space has been initialized

    request: [request: Request, channel: ServerSecureChannelLayer]

    event raised when the server receives a request from a connected client. Useful for trace/diagnostics.

    response: [response: Response, channel: ServerSecureChannelLayer]

    event raised when the server sends a response to a connected client. Useful for trace/diagnostics.

    serverRegistered: []

    event raised when server has been successfully registered on the LDS

    serverRegistrationPending: []

    emitted when the server is trying to register with the LDS but the connection has failed (backoff signal)

    serverRegistrationRenewed: []

    event raised when server registration has been successfully renewed on the LDS

    serverUnregistered: []

    event raised when server has been successfully unregistered from the LDS

    session_activated: [
        session: ServerSession,
        userIdentityToken: UserIdentityToken,
    ]

    event raised when a session is activated

    session_closed: [session: ServerSession, deleteSubscriptions: boolean]

    event raised when a session is closed
