3.0 DNP3 OVER ETHERNET (TCP)

If the M6xx meter has the Ethernet SCADA protocols option, then it will respond to DNP3 commands via
TCP. The M6xx meters can support either DNP3 or Modbus, and HTML protocols over the Ethernet link.
The table below lists the default port assignments for all Ethernet based protocols supported by the M6xx
meters.

3.1 DNP/IP

The DNP/IP (DNP Over TCP/IP) interface allows up to 3 DNP Masters to communicate with the M6xx.
Each remote IP Master may communicate with the M6xx meter via TCP. If multiple Masters share an IP
address, each Master must connect to a unique IED Listen port

For each protocol session, the Master IP address and the IED Listen Port number may be specified. The
current Settings for each session can be viewed or changed from the web browser. Use the Settings tab
to navigate to the Protocol Configuration page. A radio button selects the protocol. If the Master IP
address is set to 0.0.0.0 a Master connection will be accepted from any IP address. The default IED listen
port number for DNP3 is 20000 (see table above).

After establishment of a TCP connection from a DNP Client, the M6xx meters can verify contact by
periodically sending REQUEST LINK STATUS messages. This period is configured using each DNP
Session’s “Link Status Period” parameter (default is 300 seconds).

See appendix B for DNP configuration parameters.
