OnServerStatusRead will be fired every "KeepAlive" milliseconds.
If KeepAlive has a value greater than 0, OnServerStatusRead fires every given KeepAlive milliseconds. The event gives the actual ServerStatus (uaServerStatusDataType), which is a mandatory node (ns=0;i=2256) of an OPC UA server. If the client is not able to read the ServerStatus then a OnServerShutdown will be raised.
