5. DNP3 Ethernet Communication Setup Configuration Utility
PXM 4/6/8K DNP3 Ethernet Communications User Manual
MN150005EN January 2017 www.eaton.com
The User can set three parameters:
1. DNP Master Address
It is the address of DNP master with which the PXM
meter shall exchange DNP3 data. This address shall be
validated by PXM meter and responses shall be sent
ONLY if a request is sent by the DNP master with this
address. This address shall be used in DNP3 source
field in DNP frames from master to slave.
2. PXM Meter Address
This is the DNP3 address with which the DNP3 mas-
ter device shall identify the specific PXM meter in the
DNP network. This address shall be used in the DNP3
destination field in DNP frames from master to slave.
The PXM meter shall match the destination address in
the received frame and the User assigned PXM meter
address. If a match is found, then the frame shall be
processed further.
3. User Assigned ID/Code
The User can assign a name to the PXM meter for
identification. This helps in easy identification of the
PXM meter location by the user instead of remember-
ing the meter by the DNP3 address.

PXM DNP3 implementation uses port 20,000 for its
communication. This port is not configurable and is
fixed. To communicate with PXM meter over TCP/IP
DNP, the master must use 20,000 as port number.
5.2 Global Settings
When this page is selected, the User can configure the fol-
lowing parameters.
1. DNP Select Operation Timeout
This parameter is used for Select-Before-Operate (SBO)
operation on digital outputs (relays). If the SBO mode is
used by the master to operate meter’s digital outputs, then
“DNP Select operation timeout” parameter is used. In this
particular operation, the DNP3 master first sends a select
request for particular digital output. When this request is
received, the PXM meter starts a timer for duration speci-
fied by “DNP Select operation timeout” parameter. If the
operate command is received from DNP3 master before
this timer elapses, then that digital output is operated as
per the master request.
If this timer expires before the operate request is received,
then the operate request is rejected by PXM meter.

It is necessary that the digital I/O card is installed in
the PXM meter to use this option. SBO operation is
supported only on relays R1, R2, and R3 and these
relays should be selected in the DNP input output
section as explained later in this document.
2. DNP Default Object X Variation ( X =1, 2, 10, 20, 21, 22,
23, 30, 32, 34, 40)
The DNP3 master may send requests to get the DNP3
slave data (PXM data) objects with variation 0. In this
case, the meter can send responses with the default
variation. It is possible to configure object wise default
variation for the PXM meter on web page. The User
can select the default variation from the drop down list
given against each object.
