Network protocol defines the network transmission layer protocol (either TCP or
UDP) used with IEC 60870-5-104 network communication. The IEC 60870-5-104
standard protocol uses TCP, but for reliable slow-speed packet-switched networks
the UDP protocol can be used to minimize the packets transmitted over network.

Network port to listen defines the network port to listen for incoming IEC
60870-5-104 connections.

Note
Network idle timeout defines the idle time-out of the network connection in
seconds. If there is no network data received during the specified interval, the
device closes the connection. This parameter is required to detect partially closed
connections and to release the resources for new connections, especially if the New
connection priority parameter is disabled. The value "0" disables the network idle
time-out detection.
