byte 1: (8 bits integer) current INDEX Output
byte 2: (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).

byte 3: (8 bits integer) menu Measure – Cut-off es. 1(dec) / 10 = 0.1%, 255(dec) / 10 Æ 25.5%
byte 4: (8 bits integer) menu Batch - N.samples

byte 5: (8 bits integer) menu Batch – Diff.thr

bytes 6-7: (2 bytes 16 bit unsigned integer, MSB first) menu Batch – V.com (value expressed in the same

units and with the same decimal digits of the volume counters)

bytes 8-9: (2 bytes 16 bit unsigned integer, MSB first) menu Batch – V.pre (value expressed in the same
units and with the same decimal digits of the volume counters)

Below there is a description of the contents of each 16 bytes for every type of INDEX Output ( this index

is inserted with the second byte of the Output data):

NOTE: Setting the commands only in the state OPERATE. In the state CLEAR the commands are not

accepted.

INDEX Output = 10(dec) Flow Meter Commands

byte 0: (8 bits integer) INDEX Input: the value set the type of the Input data

byte 1: (8 bits integer) INDEX Output = 10(dec)

byte 2: (8 bits integer) command type

Type of command that is possible to insert in the byte 2:

Byte 2 = 0x06(hex) command for reset the Totalizers of the Flow Meter ( see the Flow Meter Manual and

the relative menu for to enable which totalizers to reset by this command).

Byte 2 = 0x07(hex) command for read the current Language used in the Flow Meter:

The information is returned by the byte 4 of the Input data with Index Input 32.
