Figure 50: DNP Form
Transport
Synopsis: { TCP, UDP }
Default: TCP
The network transport used to transport protocol data over IP network.
IP Port
Synopsis: 1024 to 65535
Default: 20000
A local port number on which protocol listens for UDP datagrams.
Learning
Synopsis: ###.###.###.### where ### ranges from 0 to 255 or { Disabled }
Default: Disabled
Enable or disable address learning. Learning can be disabled, or enabled on management IP
interface (empty string), or enabled on the interface with specific IP address.
If learning is enabled and remote address is not known, UDP broadcast message will be sent
and source addresses will be learned on devices that run DNP protocol. If local address is not
known, message will be sent to all serial ports running DNP protocol. Local addresses will be
learned from local responses. If TCP transport is configured, connection will be established to
the devices with the corresponding IP address.
