Current Behavior

Dear all,

I am new to this library and stumbled upon KeepAliveInterval parameter of the session. By default it induces a read of node i=2259 every 5 sec and drops the connection into unknown state upon expiry. In my test system the client connection is also dropped and a full reconnect is initiated.

Just being curious, is this a behavior found in OPC UA spec somewhere? How does it correlate with OPC UA wire protocol settings like RevisedSessionTimeout from OPC UA spec? In my test system we set values larger than 5 sec in Session handshake and get a larger revised value from the server. Is it now an additional layer on top of what OPC UA spec is telling?

BR and thanks
-Sten
