TIP: In this configuration, the SCADAPack DNP Router is acting as a DNP Server on the Ethernet
port. The Server Idle Timeout parameter will be used to determine how long this connection will
be kept open from time of last communication activity. For a Server Idle Timeout default value of 4
minutes, and an Application Layer Timeout default value of 5 minutes, there is the possibility that
the IP port will be closed, if the router is experiencing communication problems with the outstations.
In this case, it is a good idea to increase the Server Idle Timeout to at least 2x the DNP configuration
Application Layer Timeout. Or, simply reduce the Application Layer timeout to a value less than 2x
the Server Idle Timeout.
