don’t have practical effect. To every address a various function corresponds. The code number for
“on” is FF00 (hex), for “off” is 0000. Others values product the exception n.3.
Addresses(Hex format)
Function Description
0000 start / stop batch
0001 reset batch
0002 reset totalizers
0003 reset data logger
0004 reset events logger
NOTE: for reading the index value of the batch memory is necessary to activate the
batch function.
If the batch function is disabled the system return the exception code n. 4.
• FUNCTION 08, standard diagnose function of the MODBUS protocol. The following table lists the
sub-commands:
Addresses (Hex format) Function Description
0000 return query data
0001 restart communications
0004 listen mode only
000A clear counters
000B-0012 return counters value
• FUNCTION 16, function for to set parameters in the converter. As the same way as the reading
function, it is possible to write value in the memory of the meter in the format of 16 bit variables
that can be append together to form floating point variables (float) or long-integer (long) with 32
bit. The high side (MSW) start at even address, the low side (LSW) start immediately the following.
The addresses are expressed in hex format.
Addresses (Hex format) Function Description
07D0-084F Values batch memory, grouped in 64 contiguous blocks
of 8 register of memory at 16 bit for every block.
0BB8 Batch Memory index current in use
For the meaning of the memory location and their address go to the relative reading section.
5.8. CUSTOM FUNCTION
FUNCTION 110, execution of the ETP command. With this function it is possible to send a text
string to the meter in the ETP protocol format (see the relative section), the ETP command is
embedded in the MODBUS standard protcol format.
The max length of the string to send is 251 characters. The returned string form the meter is
embedded with the same structure. Also in this case the max length of the returned string is 251
characters.
With the ETP command is possible to set and to return the value of every parameter of the
converter.
For the complete list of the ETP commands see the relative section.
