SETPOINT STORAGE IN EEPROM MEMORY
The setpoint are stored in the RAM memory and lost upon instrument power off. It is necessary to
send a special command to save them permanently in the EEPROM memory. Please note that the
writing number allowed in the EEPROM memory is limited (about 100000).
The PC transmits
the ASCII string:
$aaMEMckckCR
Possible instrument responses:
-
correct reception:
&&aa!\ckckCR
-
incorrect reception:
&&aa?\ckckCR
2.
READING WEIGHT OR SETPOINT 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
= d ............. to read setpoint 4
j
= e ............. to read setpoint 5
j
= t .............. to read gross weight
j
= n ............. to read net weight
Possible instrument responses:
-
correct reception:
&aaxxxxxxj\ckckCR
-
incorrect reception:
&&aa?\ckckCR
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
ALARMS
section.
