Acyclic Index Read = 30(dec) Batch Functions
byte 0: (8 bits integer) batch status:
Format of the returned data: 1 byte containing the batch process state:
0(dec) = batch process is correctly terminated (pre-set quantity reached).
1(dec) = batch process is running (the valve is opened and the counters are running).
2(dec) = batch process is suspended (the valve is closed before the pre-set quantity is reached).
bytes 1-8: (8 bytes ASCII) memory batch name (allowed characters: 0..9, a..z, A..Z, space (32 DEC, 20
HEX))
bytes 9-10: (2 bytes 16 bit unsigned integer, MSB first) number of batch processes done for this batch
memory.
bytes 11-13: (2 bytes 16 bit unsigned integer, MSB first) value of the safety batch timer expressed in tenths
of seconds.
bytes 14-17: (4 bytes 32 bits unsigned long integer, MSB first) batch quantity value expressed in the same
units and with the same decimal digits of the volume counters.
Acyclic Index Read = 50(dec) Data Logger DATA
byte 0: (8 bits integer) check DATA on Internal Data Logger
bit 0 =1 Presence of data in the Internal Data Logger
Acyclic Index Read = 51(dec) Data Logger DATA
byte 0: (8 bits integer) number of record requested
byte 1: (8 bits integer) total number of records present in the memory
bytes 2-5: (32 bits long integer, MSB first) data saving time and date expressed in minutes starting
from 01-01-1992
bytes 6-9: (32 bits long integer, MSB first) data counted +
bytes 10-13: (32 bits long integer, MSB first) data counted -
bytes 14-17: (32 bit single precision IEEE floating point, MSB first) flow rate in technical unit
bytes 18-20: (3 bytes ASCII) counter measurement unit
