3.2. Acyclic Write Data to the Flow Meter
For the insertion of the data with the Acyclic Read Service and a Class 1 Master the Acyclic Slot is ignored
and every value is not checked in the slave. The only value used for select the type of data inserted is the
Acyclic Index.
If the master is a Class 2 master, it is necessary insert the value of the Acyclic Slot = 0 and with the value
of the Acyclic Index there is the indication to the slave of the type of data of the data inserted.
Below there is the description list of the type of the bytes that there is possible to insert with the different
value inserted in the Acyclic Index.
Acyclic Index Write = 0(dec) Setting of the value of the Data Type
byte 0: (8 bits integer) Data Type ( see the Sections Data Type and the relative Configuration )
Acyclic Index Write = 10(dec) Flow Meter Commands
byte 0: (8 bits integer) command type
Type of command that is possible to insert in the byte 0:
Byte 0 = 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 0 = 0x07(hex) command for read the current Language used in the Flow Meter:
The information is returned by the byte 2 of the Input data with Acyclic Index 22.
Byte 0 = 0x08(hex) command for Reset the slave module. After 5 seconds the module return in the data
exchange
Byte 0 = 0x32(hex) command for Autozero Calibration
