NOTES:
1.
The meter provides the permanent Modbus TCP server on port 502.
2.
Selecting the DNP3 protocol launches the second DNP3 TCP server in
addition to the Modbus server allowing simultaneous connections on
both ports. Selecting the Modbus protocol disables the DNP3 TCP
server.
3.
When you change the COM2 settings through the Ethernet port, the
device port restarts so communications will be temporarily lost. You
may need to wait some additional time until PAS restores a
connection with your device.
Setting Up Ethernet
Using the Front Display
Select
nEt
from the main menu.
This menu entry appears only if the
optional Ethernet module is plugged into the meter.
It allows you to
set up the meter network address and the default gateway.
