Dnp 3; Protocols - Ametek UPLC CU44-VER04 Applications Manual

The UPLC™ is available with separate protocols.
The Distributed Network Protocol, DNP 3; and the
IEC61850 object oriented standard.

8.1 DNP 3

The UPLC™ can communicate via DNP 3 using
one of the following ports/standards.
• Std. rear 9-pin D-sub connector (J4) via RS-
232* (Use Std. Straight-through 9-pin Serial
Cable, Male to Female)
• Standard rear 9-pin D-sub connector (J4) via
RS-485 (TX- = pin#2, TX+ = pin#8, RX- =
pin#3, RX+ = pin#7)
• Optional rear Ethernet connector (TX1/RX1
or TX2/RX2) via TCP/IP–UDP
The account holder must have "User" privileges to
set the DNP communications.
The UPLC™ DNP communications works in a
slave mode as an outstation device and supports
level 1 & 2 of the DNP 3 protocol. A DNP device
profile can be generated by downloading the
UplcDnpCfg.xml file into a folder with the appro-
priate DNP device profile xsd, xsx & xslt files
(2009) and then opening the
UplcDnpCfg.xml file.

3) Finally, click on the DNP tab.
If the physical layer is set to RS-232 or RS-485
mode, a Baud rate must be chosen. For the
TCP/IP–UDP mode, an IP port must be chosen.
• Physical Layer = RS-232 or RS-485
• Baud = 2400, 4800, 9600, 19200, 38400 or
115200
• Physical layer = TCP/IP–UDP
• IP Port = 20000 (default) or 49152–65535
• UPLC™ DNP address = 1–65519
• Link Layer Confirm = Never, Multi or
Always
• Unsolicited Responses = Disabled or
Enabled
If "Unsolicited Responses" is enabled, the follow-
ing additional settings must be made.
• Master DNP Address = 1–65519
• Confirmation Timeout (secs) = 1–60
• Number of Retries = 1–5 or indefinite
