Configuration in STEP 7
5.7 Configuring TIM modules
TIM DNP3
122 System Manual, 12/2015, C79000-G8976-C253-04
●
Master station monitoring time[s]:
Monitoring time for the DNP3 master station. Within the configured time, the TIM expects
a signal from the DNP3 master station at the application layer.
If the TIM does not receive a signal from the master station during this time it assumes a
fault on the master station, outputs an error message to the diagnostics buffer and, if
configured, sets the relevant bit in the PartnerStatus system object to zero. The
configured value is transferred to the connected DNP3 master stations.
When the monitoring time has elapsed, the master station must send a 'Daily
Measurement' message to the station that must be acknowledged by the station. If the
station does not reply to the message, it is classified as being unreachable by the master
station.
If this parameter is > 0, connection failure at the TCP level that is detected using the
keepalive mechanism is not signaled (see above).
Range of values: 0...65 535
Default: 0 (no monitoring)
Note: This mechanism can also be used for monitoring passive redundant paths.

Clicking the "DNP3 parameters" button opens the "DNP3 parameters" dialog, see section
"DNP3 parameters" dialog (Page 123).
If a WAN interface is selected, the parameters of the interface become visible.
WAN 1 corresponds to interface X1, WAN 2 corresponds to interface X2.
Behind each interface that is to be connected with a network, there must be a network node
of the corresponding type and this can be recognized by the "Properties" button being
available for selection.
For each WAN access, you have the following options:
●
Interfaces drop-down list
– Drop-down list locked with "DNP3 dedicated line" display:
There is already a network node for this interface. Using the "Properties..." button, you
can branch to the "Properties" dialog of the network node to make parameter settings.
Using the "DNP3 parameters" button, you open the dialog with the same name; for the
parameter assignment, refer to the section "DNP3 parameters dialog". With the
"Delete..." button, you can remove the network node.
The "Properties" dialog of the interface is described in the section dealing with
parameter assignment of network nodes.
– Drop-down list selectable with "DNP3 dedicated line" display:
There are not yet any network nodes for this interface. With the "New..." button, you
create a network node of the type displayed in the interface list box.
