CHAPTER 3: ETHERNET INTERFACE DNP ETHERNET PROTOCOL SETTINGS
SR3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE 3-13
DNP port allocation
The DNP Eth Channel 1 Port and DNP Eth Channel 2 Port settings select the
communications port assigned to the DNP protocol for each Ethernet channel. When this
setting is set to "Network-TCP" the DNP protocol can be used over TCP/IP channels 1 or 2.
When this value is set to "Network-UDP" the DNP protocol can be used over UDP/IP on one
channel only.
□ Configurable □ When Device Restarts
□ Only certain objects □ When Status Flags Change
⊠ Sometimes No other options are permitted.
⊠ ENABLE/DISABLE unsolicited Function codes
supported
Explanation of ‘Sometimes’: It will be disabled for
RS-485 applications, since there is no collision
avoidance mechanism. For Ethernet communication
