NOTES
In meters with the Ethernet option, the device provides the permanent Modbus TCP server
on port 502. Selecting the DNP3 protocol on the Ethernet port launches the DNP3 TCP
server in addition to the Modbus server allowing simultaneous connections on both ports.
Selecting the Modbus protocol disables the DNP3 TCP server.
When you change the COM1 settings through the Ethernet port, the device port restarts so
communications will be temporarily lost. You may need to wait some additional time until
Power Software restores a connection with your device.
