2. Serial Protocols
ROS® v3.11User Guide 71 RMC30
Default: IP Port
The IP port on which remote device listens to UDP datagrams. This port is either the same
IP port that devices in all networks listen to, or can be learned from the UDP datagram.
Learning
Synopsis: ###.###.###.### where ### ranges from 0 to 255 or
{ Disabled }
Default: Disabled
Enable or disable address learning. Learning can be disabled or enabled on a management
IP interface (empty string), or enabled on the interface with a specific IP address. If learning
is enabled and the remote address is not known, a UDP broadcast message will be sent
and source addresses will be learned on devices that run the DNP protocol. If the local
address is not known, a message will be sent to all serial ports running the DNP protocol.
Local addresses will be learned from local responses. If the TCP transport is configured,
a connection will be established to the devices with the corresponding IP address.
Aging Timer
Synopsis: 60 to 1000
Default: 300 s
The time of communication inactivity after which a learned DNP address is removed from
the device address table. Entries in the Link Statistics Table with the aged address will be
kept until the statistics are cleared.
Link Stats
Synopsis: { Disabled, Enabled }
Default: Enabled
Enables link statistics collection for this protocol.
DSCP
Synopsis: 0 to 63
Default: 0
To set the DS byte in the IP header. DS byte setting is supported in the egress direction
only.
