Parameter Options Default
Device IP Address 192.168.0.203
Network Subnet Mask 255.255.255.0
Network Default Gateway 192.168.0.1
TCP Service Port 502 = Modbus/TCP
20000 = DNP3/TCP 502
NOTES
1. The meter provides the permanent MODBUS TCP server on port
502.
2. Selecting the DNP3 TCP service port launches the second DNP3
TCP server allowing simultaneous connections on both TCP
ports. Selecting the MODBUS TCP port disables the DNP3 TCP
server.
The TCP service port can also be changed trough the COM2
serial port setup. Changing the communication protocol for the
port automatically changes the TCP port for the Ethernet.
3. When you change the device network settings through the
Ethernet port, the device port restarts so communication will be
temporarily lost. You may need to wait some additional time
until Power Software restores a connection with your device.
