update a Logix UDT array (see example Logix code) to allow the Logix application code to use
it.
NOTE
: Refer to the Logix example code which provides a mechanism to extract
the DNP3 Events from the Logix Master Events Tag.
Once there is confirmation from the Logix controller that the event has successfully been
written to an index offset of the Logix Master Event Array the DNP3 Router will then send a
confirm to the DNP3 Outstation that the event has been received and it can be removed from
its internal log.
The configuration below shows the Logix Controller selected (from the list of controllers in
the Scheduled Logix Controller Map). Once this is done the user can browse to the required
Logix tag (using the Tag browser) to enable the DNP3 Router to unload DNP3 events into the
Logix controller.
Figure 3.38. – DNP3 Master Event Unloading Configuration
The buffer size in the configuration must match the array size of the Master Event Tag in the
Logix controller.
NOTE
: This buffer size value must not exceed the Logix controller tag array size.
If this is the case the unloading of events to the Logix controller will not operate
correctly.
Below is an example of how the DNP3 Router would unload events from the DNP3 Outstations
(based on the configuration in the image above). DNP3 events can be unloaded from DNP3
Outstations either by one of the following methods:
Polling each Event Class (Class1, Class2, Class3).
Enabling Unsolicited Responses from each DNP3 Outstation.
