Rice Lake Signal Conditioning Transmitter/Indicators - Manual (Page 57)

Operation 53
Setpoint Values Setting:
The PC transmits : $aaxxxxxxyckckCR
in which:
xxxxxx = 6 characters for the setpoint value (48 ? 57 ASCII);
y = A (set the value in the Setpoint 1)$01010000A40CR
y = B (set the value in the Setpoint 2)$01010000B42CR
y = C (set the value in the Setpoint 3)$01010000C43CR
Possible instrument responses:
- correct reception: &&aa!\ckckCR
- incorrect reception: &&aa?\ckckCR
Setpoints Storage Into EEPROM Memory:
The setpoints value relevant to the two setpoints programmed via the PC are stored to the RAM volatile 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 number of writes allowed in the EEPROM memory is limited (about
100000).
The PC transmits: $aaMEMckckCR
$01MEM44CR
Possible instrument responses:
- correct reception: &&aa!\ckckCR
- incorrect reception: &&aa?\ckckCR
Reading Weight, The Setpoint And The Peak (If Present) From The Pc:
The PC transmits: $aajckckCR
in which:
j = a to read setpoint 1$01a60CR
j = b to read setpoint 2$01b63CR
j = c to read setpoint 3$01c62CR
j = t to read gross weight$01t75CR
j = n to read net weight$01n6FCR
j = p to read the gross weight peak if the ASCII parameter is set as NOdU60; if, instead the ASCII parameter
is set on NOd td the gross weight will be read.
To read the points, set the FS
tE0 equal to 50000. $01p71CR
Possible instrument responses:
- correct reception: &aaxxxxxxj\ckckCR
- incorrect reception: &&aa?\ckckCR
- if the peak is not configured: &aa#CR
in which:
xxxxxx = 6 value characters of the required weight;
In case of negative weight, the first character on the left acquires 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
NASS, 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
