TIP: Even though a SCADAPack outstation will respond successfully to master request,
without is routing entry to the master, it is a good practice to always define such a routing
entry from an outstation to its master. Moreover, without a routing entry defined to the
master, the outstation will not know which port to send out unsolicited messages, if
configured, to the master.
v. Click on OK to add this entry to the routing table and return to the Routing dialog.
The completed routing table should look like this:
This next step assumes you have digital inputs mapped to Modbus registers 10001 and 10002.
5. From the DNP Configuration Panel, click on the Binary Inputs tree node.
a. Set the Starting DNP Address to 1.
b. Set the Event Report Method to Log All Events.
Note: If you want to log all events and not only the most recent, you must set the Event
Reporting Method to Log all Events.
c. Set the Event Buffer Size to 100. The completed panel should look like this:
d. Click on Add to create a new DNP3 binary input point. Observe that a new binary input
point is now visible under the Binary Input tree node with DNP Address 1 (Starting
Address)
e. Leave the default associating Modbus Address as 10001.
f. Leave the default Event Object as Class 1.
g. Set the Debounce property to 10.
TIP: It is a good idea to set a non- zero Debounce on unfiltered inputs, to avoid
noise being collected as Class events. The same applies for analog inputs. A non-
zero Deadband will prevent noise from being collected as Class events.
9. Set the Debounce property to 10.
