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.
