READING WEIGHT, SETPOINT AND PEAK (IF PRESENT) FROM PC
The PC transmits the ASCII string: $aajckckCR
where: j = a ............. to read setpoint 1
j = b ............. to read setpoint 2
j = c ............. to read setpoint 3
j = t .............. to read gross weight
j = n ............. to read net weight
j = p ........ to read the gross weight peak if the parameter is set as ; if,
instead, the parameter is set on the gross weight will be
read. To read the points, set the parameter equal to 50000
Possible instrument responses:
- correct reception: &aaxxxxxxj\ckckCR
- incorrect reception: &&aa?\ckckCR
- In case of peak not configured: &aa#CR
where: xxxxxx ...... 6 characters of the required weight value
Notes: in case of negative weight, the first character from the left of the weight characters takes on
the value “-” (minus sign - ASCII 45). In case of weight value is under -99999, the minus sign “-” is
sent alternated with the most significant figure.
Error messages:
in case of an instrument alarm for exceeding 110% of the full scale or 9 divisions above the value of
the parameter , the instrument sends the string:
&aassO-Lst\ckck
in case of faulty connection of the load cells or of another alarm, the instrument sends:
&aassO-Fst\ckck
where: s ................... 1 separator character (32 ASCII – space)
Generally refer to the SERIAL PROTOCOLS ALARMS section.
SEMI-AUTOMATIC ZERO (WEIGHT ZERO-SETTING FOR SMALL VARIATIONS)
The PC transmits the ASCII string: $aaZEROckckCR
Possible instrument responses:
- correct reception: &&aa!\ckckCR
- incorrect reception: &&aa?\ckckCR
- the current weight is over the maximum resettable value: &aa#CR
