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.
Selection of the required connections
If no connections are displayed in the left-hand window, the required connections must be
transferred from the right-hand window. Follow the steps outlined below:
1.
Expand the tree structure by clicking on the branch symbol (+) or by double-clicking on
the connection group. The tree structure opens.
2. Select a possible connection in the right-hand window.
3. Enter the possible connection as a configured connection in the left-hand window by
–
selecting the Edit / Apply menu or
– pressing the right mouse button and selecting Apply in the displayed shortcut menu.
If alternative communications paths exist and you want to use them, expand the possible
connection structure in the possible connections by double-clicking on it and select the
connection and apply it.
Redundant connections
With redundant connections, for example those of a redundant DNP3 master station, the
higher connection in the tree structure is the preferred path and the lower connection is the
substitute path. The master station always sends via the preferred path first. It only sends via
the substitute path if the preferred path fails.
