Troubleshooting
Verify Proper Operation
Once the gateway is installed on your Network, verify
proper operation by testing its functionality. SCADA
networks vary greatly, so there is no simple way to
describe testing all possibilities. Use a scientific method
and keep careful records of all installation and
troubleshooting steps. For example, consider the following
method…
1. Verify that the gateway has a proper LAN connection by
pinging it. If it responds to a ping then…
2. Verify the unit’s configuration by using telnet to port 8000
or by checking it using a web browser. If it looks good
then…
3. Attempt a poll from the DNP-3 polling master computer.
If that works correctly, you’re ready to continue with
DNP03 operation. IF not…
4. Check the gateway’s statistics to see if it received the LAN
activity and passed the polls to a serial port. If not, there is
likely a problem with IP addressing or the host computer is
not configured correctly for the gateway’s LAN. If the
gateway receives the LAN packets and doesn’t pass them
to the serial port, then check its configuration. If the
counters indicate that the poll was passed to the serial port,
but there’s no response…
5. Verify correct RS-232/RS-485 configuration. Verify
cabling to the RTU. One of these is likely incorrect. Or…
6. Verify the RTU configuration. Perhaps it’s not correctly
configured.
