DNP3 IP Networking Parameters
For the IP networking services, the following configuration parameters are available in the SIPROTEC device
(i.e. in the DNP3 IP mapping file, see chapter 2):

Description
The TCP ports to listen on.
Port numbers must be different.
If both port numbers are equal, only one
DNP3 IPserver is started, i.e. only one TCP connec-
tion is available.
List of IP addresses to accept TCP connections from.
All entries = *.*.*.*:
accept connection from any TCP client.
At least one entry is not = *.*.*.* and
one or more entries = *.*.*.*:
entries with *.*.*.* are ignored.
Reload value for the keep-alive timer to monitor the
status of an active TCP connection on DNP3 IP appli-
cation layer level. The keep-alive timer is restarted
whenever a message is received from the master.
If the timer times out, the device (DNP3 IP outstation)
transmits a Data Link Layer status request which
must be responded by the master or the connection
is assumed to have broken down and will be closed.
Determines whether the device (DNP3 IP outstation)
expects and evaluates time synchronization from
DNP3 IP master (see chapter 4.2).
Determines in case of two connected DNP3 IP clients
which one acts as time master for the time synchroni-
zation via DNP3 IP.
If only one client is connected, then this one also is
time master.
Acc. to "Time Synchronization" in DNP3 IP Spec. Vol.
5, the time for DNP3 IP time synchronization shall
(since Jan. 1st, 2008) correspond to Universal Coor-
dinated Time, UTC.
This setting is used to support DNP3 IP clients which
send time synchronization in local time but should
normally remain unchanged to default value.
