2) For the Rate meter/totalizer or Batch meters:
[Sa][S][SP][S][SP][S][SP][S][hh][]
b) For “X” Command:
[hh][]
For Type (3) Commands:
[hh][]
Where “nn” is the meter’s address HEX format and is omitted from the response format if the communication is
in the point-to-point mode. “ccc” is the three (3) character command prefix letter and it’s suffix number. “d” is
one ASCII character.
“[hh]” is the optional checksum “CR” is carriage return “[]” is optional line feed.
“Sa[b]]” is the optional alarm status character followed by the optional peak/valley status character. Alarm
status character is preceded by the chosen plain-ASCII separator character, or , depending on how
you want this data displayed.
“S” is the separator followed by the decimal-digit measurement value, with plain-ASCII minus sign (if
any) and decimal point.
“[S]” is the optional inclusion of the separator followed by any one of the three added decimal-digit
values listed above.
“[uuu]” is the optional three units-of-measure characters (letters or other printable plain-ASCII symbols)
preceded by a space; “” is the terminating plain-ASCII Carriage Return character.
[] optional line feed.
NOTE: A positive overflow in any one of the s results in the transmission of “?+999999” for that value;
negative overflow sends “?-999999”.
8.4 Data Length Corresponding To The Response Structure
For “R” and “G” Commands:
Data is equivalent to the “W” and “P” Commands respectively (see Table 8-2).
For “V01” and “X” Commands:
a) Value has 7 characters (like 724.352 or –233.45), unless overflow occurs in which case it consists of 8
characters (see note above)
b) Status characters “a” or “b” are each one character.
For “U” commands:
Data is one character.
8.5 Error Response
The meter is capable of detecting the different errors during the communication process and will transmit an
indicating message to the host controller.
8.5.1 Error Response Format
1. Echo mode
[nn]?ee[]
2. No echo mode
