Summary and detailed map configurations are also available in the
DNPMAP.TXT and DNPMAPnn.TXT files from the SEL-421 FTP interface.
The individual file names associated with the detailed custom map settings
follow the DNPMAPnn.TXT naming convention.
Testing
Use the TEST DB command to test the communications card relay database.
The TEST DB command can be used to override any value in the relay
database. Since the relay database provides data to the communications card
interfaces, the TEST DB command can also be used to test the data read
operations of any of the protocols on an installed Ethernet card. Use the
MAP 1 command and the VIEW 1 command to inspect the relay database
(see MAP on page R.9.27). You must be familiar with the relay database
structure to use the TEST DB command effectively; see Communications
Card Database on page R.4.18 for more information.
DNP LAN/WAN Documentation
