3.2.6. COMMAND FORMATS
A command is defined as an operating code of 1 byte specifying the type of operation required. The reply to this
command is the return of one block with the requested data having the same command code + 128 (80H). The
following command codes are available:
codice Action performed by the measuring device after receiving the command.
0 Send the type of instrument and version of the software ( all model )
1 Send the process data (for all models)
2 Send the data logger’s data (ML210/211/212)
3 Receive date and time (ML210/211/212) reset the enabled totalizers ( all model )
4,5,6,7,9,
10,13
RESERVED
8 Send or receive data for batch (ML210 / ML3-F1)
11 Send events data(ML210/211/212)
12 Send min/max (ML210/211/212)
14 Set set-point (ML212)
NOTE: the commands indicated with the term "RESERVED" are used during factory calibration and diagnosis, are
protected by a special password and must not be used by the user under any circumstance.
In this description, the command codes in hexadecimal and (decimal) format and the related data format are shown.
The numeration of the bits is from 0 (LSB) to 15 (MSB). The numeration of the bytes received is from 0 to N, where 0
is the first byte received and N is the last.
3.2.7. READING THE TYPE OF INSTRUMENT AND THE SOFTWARE VERSION
Command code: 0
