Rules for connection configuration (DNP3)
● For each path (physical network) only one connection can be configured.
● Between a DNP3 master station and a DNP3 station, a maximum of 2 paths can be
configured.
Exception: a redundant DNP3 master station is involved. In this case, a station TIM can
have a maximum of 4 connections on 2 paths (interfaces).
● In DNP3 dedicated line networks, connections can only be configured between the
following partners:
– DNP3 master station - DNP3 station
DNP3 master station - node station
Node station - DNP3 station
● In Ethernet and dial-up networks, connections between two stations can also be selected
for direct communication.
Functions of connection configuration
To make configuration of the required connections as simple as possible for the user, the
SINAUT Configuration Tool uses the following strategy:
● The entire currently configured network is analyzed. All potential communications
subscribers from the engineering software perspective are assigned a subscriber number
(DNP3 address) if they do not already have one. The subscriber numbers for CPU
modules and third-party stations are assigned starting at no. 1, for TIM modules there are
assigned starting at no. 1001.
● A tracking algorithm detects all connections in the current network. These connections
can also extend over several LAN and WAN networks. The connections permitted based
on specified rules are represented on the right as possible connections in a tree structure.
● Telecontrol connections that have already been configured are displayed in the left-hand
window for configured connections. Each of the connections loaded there is then checked
to establish whether its configured parameters match the current network and hardware
configuration. If this is not the case, and error message indicating incorrect connections is
displayed as soon as the connection configuration is opened and the bad connection is
displayed in red in the configured connections window.
If a station of the type other station was configured in NetPro, connections from the stations
to stations of the type DNP3, PG/PC, or a PCS 7 control center are not displayed. This does
not, however, mean that these connections do not exist. These connections are in fact
displayed in the opposite direction; this means, for example, from a DNP3 station to a station
of the type other station.
As a general rule, a connection displayed in the configured connections in only one direction,
works in both directions.
