4�4�3�- CONFIGURATION OF MAXIMUM DEMAND
The
CVM-NET4+-MC
can calculate the maximum demand using the scrolling or fixed window method,
depending on the selection.
The maximum demand is simultaneously calculated in kW, kVA, A and phase current.

Example of maximum demand programming for Channel 1, with a 15-minute period in scrolling system:
TX
: NP 10 274C 0002 04
000F 0000
CRC
RX : NP 10 274C 0002 CRC
4�4�3�1�- Reading the maximum demand configuration
The user has a Modbus command as extra information for reading the maximum demand configura-
tion:
TX
: NP 04 274C 0002 CRC
RX : NP 04 04 000F 0000 CRC
4�4�4�- DELETING MAXIMUM AND MINIMUM VALUES
The CVM-NET4+-MC records all the maximum and minimum values of each measured parameter in
the Modbus/RTU variables table.
A command is available for resetting these records:
TX
: NP 05 0838 FF 00 CRC
RX : NP 05 0838 FF 00 CRC
