6. DNP is a very extensive protocol with multiple
conformance levels and various data representations.
Inconsistencies between what a SCADA Master
expects and what a virtual DNP profile specifies lead to
puzzling results in the control room. SCADA Masters
are complex software themselves and getting access to
the raw data may be incongruous. Raw traffic capture
data is critical for Eaton engineers when diagnosing
these issues.
Virtual settings
1. Upload Profile – Select a file provided by Eaton to
configure the NPServe DNP Virtual configuration.
2. Profile – Select which uploaded profile to use.
3. Slave Address – Set the DNP Slave address of the
NPServe.
4. Master Address – Set the expected DNP Master
address.
5. Submit Changes – Apply changes in this tab to the
NPServe Configuration.
Possible troubleshooting
1. Ensure that the NPServe has a valid SCADA
configuration.
2. Ensure that Communications settings are set up
correctly.
3. If bytes are received, then Master is not reaching the
NPServe.
4. If bytes are received but not transmitted, NPServe is
rejecting requests from the Master, possibly due to
mismatched DNP addresses.
5. Traffic capture can provide insights into some issues;
please initiate to find more low level information.
Diagnostics
1. Download a diagnostic file to submit to Eaton for
further troubleshooting.
2. Display INCOM Comm Statistics:
●
●
Displays low-level INCOM communications statistics.
Most counters are intended for Eaton troubleshooting
but the following are end user interpretable:
●
●
BCH Errors – Counts the number of corrupted data
messages due to bad wiring, mismatched addresses or
other INCOM issues
●
●
The second table is a per device statistics table.
Non-zero values for any statistic indicate possible
problems with the specific device or wiring.
System
This page is used to verify the firmware version and to
upload necessary firmware updates as necessary.

NPServe can be reset to factory default status if
desired. It is recommend to save the configuration
before resetting.
USB maintenance port
The USB Maintenance port provides access to a graphical
maintenance web page via a USB-to-Ethernet connection.
Required components
●
●
Ethernet Cable
●
●
Recommended connector – Plugable USB 2.0 OTG
Micro-B to 10/100 Fast Ethernet Adapter for Windows
Tablets & Raspberry Pi Zero (ASIX AX88772A chipset)
●
●
Host PC or Laptop
Accessing the maintenance web page
1. If using a laptop, disable the wireless Ethernet
functionality.
2. Connect one end of the Ethernet cable to the plugable
adapter.
3. Connect the other end of the Ethernet cable to the host
PC.
4. Plug the MicroUSB end of the adapter into the
NPServe MicroUSB port.
5. Open a web browser and go to the following URL:
http://eaton.console.
You should now be at the maintenance page.
Troubleshooting the access procedure
1. Make sure the wireless is disabled.
2. Try to browse to http://10.42.83.1 instead of http://
eaton.console.
3. Make sure your IP address is similar to 10.42.83.100
(last number can vary).
4. Try rebooting the Host PC.
