defined in the routing table. See Chapter 0 for an explanation of using and configuring DNP
Routing.
The advantage of this routing ability is that the SCADA system can communicate directly with the
SCADAPack controller and the SCADAPack controller can handle the communication to remote
DNP slave stations.
The DNP Routing table displays each routing translation as a row, with column headings, in the
table. Entries may be added, edited or deleted using the button selections on the table. The table will
hold a maximum of 128 entries.
The DNP Routing property page is selected for editing by clicking DNP Routing in the tree control
section of the DNP Settings window. When selected the DNP Routing property page is displayed.
Notes:
 Routing must be enabled for the controller serial port in order to enable DNP routing.

 TelePACE version 2.64 cannot open files created with version 2.65, unless the Routing table is
empty.
