B) DISPLAY BACKLIGHTING
The SETUP MENU is added with a Setup page on
display backlighting control with commands DISP
ON, DISP OFF and DISP AUT (automatic
backlighting for 10 seconds at each keystroke). The
life of the battery is about 45 hours with DISP ON
(the first five hours of which with backlighting on
and the following 40 hours with backlighting off) and
approximately double with DISP OFF.
C) RESTORE DEFAULT SETUP PARAMETERS
The SETUP MENU includes the possibility to restore
the default settings by using a command (TV ratio,
TA ratio, Configuration setup, Harmonics setup,
COM Setup).
D) DISPLAY OF ACTIVE POWER MEASURE OF
SELECTED HARMONIC
In the page displaying the RMS values relative to
the harmonic selected, there is now the possibility
to see the Active Power value (besides the values
of V, I and Power Factor) by keeping the Sel key
pressed.
24
This function allows you to store in a special flash-
type auxiliary memory (1024Kbyte) the entire range
of measures managed by NANOVIP PLUS, with a
maximum of 4032 recorded blocks of measures at
intervals from 2 second to 1...99 minutes.
The campaigns are recorded through the menu.
The SETUP MENU allows access to 4 pages for
setting data recording functions:
• Date setup
• Time setup (date and time are included at the top
of every record)
• Setup of the time interval between two recordings
(every 2 seconds, or at intervals of 1...99 minutes)
• Deletion of recorded data.
In the LOG CTRL MENU the recording of the
measure campaigns can be activated or deactivated;
this menu also displays the percentage recorded in
memory and the programmed rate of recording.
Once activated, the data LOG continues until it is
either deactivated or the memory is full: during this
time the part of the Setup menu relative to the LOG
(see the block diagram on the menu pages) is
deactivated; if the device is turned off and then
turned on again recording starts again.
In the MEAS PAGE two more pages are included
with display of the date and time.
To download data by serial line, see the dedicated
section.

D13= lsb zero corresponding to samplings of second frame (Current)
D14= msb zero corresponding to samplings of second frame (Current)
D15= lsb calibration factor relative to second frame (Current)
D16= msb calibration factor relative to second frame (Current)

NOTE: Using the sampling values relative toVoltage and Current, the value of the measures of the different
quantities can be reconstructed. Formulas for a single-phase connection are given below:
E) DOWNLOADING OFVOLTAGE AND CURRENT WAVEFORM
The format of the string transmitted by NANOVIP PLUS containing 200 waveform samples is as follows:
E:0103 D1 D2D3D4 D5D6 D7D8D9 V1..V200 D10D11D12 D13D14 D15D16D17 I1..I200 CS CRLF
Where :
: = start Modbus string
01= NANOVIP PLUS default address
03= data reading command
D1= number of frames inside the data buffer where a frame is equal to an entire sampling for one signal
(either Voltage or Current)
D2= type of signal identified by the first frame

index.
H) SOCKET FOR EXTERNAL DC FEEDER
A socket has been added for external feeder with
output 6 VDC (+4% -35%), 150 mA, 0.15 A.

F) AUTOSCROLL MANAGEMENT
During activation of the measures LOG(storage),
the Autoscroll of the harmonic displayed, when
enabled, increases the harmonic index at each
recording cycle. The frequency of the increment
thus coincides with the “LOG_RATE” and enables
the recording of all 24 Harmonics consecutively.
In the 3 pages displaying the Harmonics the status
of the SCROLL enabled and commanded by the
LOG function is shown by turning on MEM in the
display.
G) MODBUS COMMAND FOR SETTING A
DETERMINED HARMONIC
The NANOVIP PLUS includes a Modbus command
that allows you to set the immediate calculation of
a determined harmonic.
The Modbus command to be sent is the following:
:01060279 Hn 00 Crc CR LF
where :
: = start of Modbus string
01= default address of NANOVIP PLUS
06 = write command
0279 = Harmonic address
Hn = value from 0 to 24 to set Harmonic desired
00 = value not managed by NANOVIP PLUS used
only to complete the Modbus string
Crc = check-sum
CR = carriage-return
LF = line-feed
Note that this type of operation remains valid only
when autoscrolling of the Harmonics is disabled.
If this is not the case, the Modbus command sets
the Harmonic desired, but the autoscrolling, starting

DOWNLOADING DATA ON MEASURE
CAMPAIGNS STORED IN INTERNAL MEMORY
The downloading of recorded data takes place
through Modbus commands:
- Command for request of number of records
memorized;
- Command for request of number of records starting
with number m.
Using the Modbus protocol for data request made
it necessary to assign the reading command with
a range of virtual addresses that would simulate
the data request from memory; specifically, the
address 0x4000 was assigned to the request for
the number of records stored, whereas the range
of addresses of records stored ranges from 0x8000
to 0xEE40; which are the 28224 max records that
can be stored.The transmission takes place only
at 8 bits;up to 7 records can be transmitted through
a Modbus command.
Format of the request string:
“:0103 4000 0001 3B”+ cr lf
Request of number of records stored
“:0103 xxxx yyyy LL” + cr lf
Request of yyyy records starting from number xxxx;
“:0105 0006 0000 F4” + cr lf Set UART 8 bit
“:0105 0007 0000 F3”+ cr lf Reset UART
Given that the test on the reception of a Modbus
command by the NANOVIP PLUS MEM takes place
when the calculation is finished, there would be the
transmission of each record block requested
approximately every second, which is the time
NANOVIP PLUS MEM takes to perform the measure.
To accelerate the total downloading of the memory,
as soon as the first data request is made you do
not return immediately to performing the next
measure, but “listen” for a set amount time to the
serial to receive the next command for downloading
data. When entering the maximum transmission
speed at 38400 baud, the maximum time for
downloading all the memories completely (1
Megabyte) is 15 minutes.
Format of transmitted data:
Response string for request of number of records
stored:
“:0103 01 xxxx LL” + cr lf
xxxx represents the number of records stored
Response string for n record request :
“:0103 nn
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AABBBBBBBBBBBBBBBBBBBBBBBBB… LL”
+ cr lf
- nn represents the number of words transmitted
- A max. of 7 records of 32 bytes follow; these are
the records requested starting with the first one.
The format of the string transmitted by the NANOVIP
PLUS MEM is not pure Modbus ASCII as that of
the other strings; the max. 7 records are in an 8 bits
binary format, not 7 bits ASCII, so the Uart must be
set at 8 bits with the special command before making
the transmission, then the setting restored with a
further command.
