PowerSmart+ Power Quality Meter 69
Parameter Options Default Description
Response delay 0-1000 ms 5 ms The minimum time after
the last request character
is received to start the
transmission.
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 Power
Software restores a connection with your device.
Setting Up Ethernet
Using the Front Display
Select Network Setup from the Device Setup 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.
See Viewing and Changing Setup Options in Chapter 3 for information on
configuring parameters via the front display.
Using Power Software
Select Communications Setup from the Meter Setup menu, and then
click on the Network Setup tab.
