A.4 On Board Memory Downloading - Elcontrol Microvip 3 plus User Manual

A.4 On-board Memory downloading via serial line
Use the following command sequence:
1. 8 bit UART Setting
In order to have a correct download of data stored, UART has to be set to 8 bits.
N.B.
This setup is necessary because the data stored inside the internal memory are in decimal format.
PC Request:
:01 05 0006 0000 LRC crlf
2. Request for the Number of stored records:
PC Request:
:01 03 4000 0001 3B crlf
3. Request for n stored records:
PC Request:
:01 03 xxxx yyyy LRC crlf
xxxx = Address of the starting record (8000h..9EA0h)
yyyy = Number of records to be transmitted
(0001, 0002, 0003 o 0004)
Example 1:
PC Request:
:0103 8000 0001 7A CR LF
Microvip3 Plus Response (hexadecimal) in case of a campaign of rms meas. in Three-phase, Standard1 mode, Star insertion:
:010339
where 01 = address
03 = reading command
39 = number of transmitted words
D1= 20 (Configuration)
The first byte of each record is that one included in the configuration of the instrument at the moment of the measurement storing inside
the internal memory . Its format is as follows:
Bit 7, 6 = type of campaign
Bit 5 = single-phase/three-phase
Bit 4, 3 = instrument configuration
Bit 2 = type of insertion
Bit 1, 0 = phase number
D2 = 01 (day) D3 = 06 (month)

Microvip3Plus Response:

Microvip3Plus Response:
:01 03 02 nnnn LRC crlf
where nnnn = number of stored records
Microvip3Plus Response:
:0103 nn rrr...rrr rrr...rrr LRC CR LF
where nn = number of WORDS transmitted ( in the standard Modbus nn
should be the number of bytes !)
rrr...rrr = it is the record of 113 bytes stored and transmitted in binary
format ( therefore it is necessary an 8 bit transmission ).
