Figure 71: DNP protocol configuration settings
The following settings are available for DNP protocol communications.
DNP Channel 1 Port, DNP Channel 2 Port
Range: None, COM1-RS485, Network-TCP, Network-UDP
Default: None
These settings specify the communications port assigned to the DNP protocol for each
channel. Once DNP is assigned to a serial port, the Modbus protocol is disabled on that
port. When this setting is set to "Network-TCP", the DNP protocol can be used over TCP/
IP on channels 1 or 2. When this value is set to "Network - UDP", the DNP protocol can be
used over UDP/IP on channel 1 only.
Changes to the these settings take effect only after power has been cycled to the relay.
