Scaime IPE100 - Reading Weighs from Alibi Memory; Serial Commands for Alibi Memory Management

IPE100 indicator NU-IPE100-IO-USER-E-0212
50
With each storage, the weigh number is increased of 000001; when it reaches the value 131071, it restarts from 000000
and the rewriting number increases of 00001.
If the weigh can not be saved in the alibi, the numeric ID will be substituted with the message "NO".
For example:
If the weigh which has been stored is the following:
“PIDST,1, 1.000kg, 1.000kg,00126-131071”
the following will be:
“PIDST,1, 1.000kg, 1.000kg,00127-000000”
NOTE: it’s possible to read the last 131071 weighs.
16.1 READING OF THE WEIGHS CARRIED OUT
Through function 427, combinable with the desired key (<< F.KEYS >> step, TECHNICAL MANUAL.) it’s possible to read
a carried out weigh:
first enter the rewriting number of the Alibi memory (rEW.id), confirm with ENTER, and then enter the weigh number (id)
and press ENTER. The ID is accepted only if valid.
If the alibi memory is empty the message “EMPTY” appears on the LCD display for a few instants; if the ID code entered is
not valid, the “no id” message appears for a few instants, and then one exits the step.
By entering a valid ID code, the LCD display shows the following data, selectable through the arrow keys   :
Ch.X in which X is the selected channel number (from 0 to 4)
Gross weight value with unit of measure;
Tare weight value with unit of measure;
Press C to exit the reading state of the weighs.
NOTE: It is possible to read the weigh carried out also through the PC serial line (see the “WEIGH READING” serial
command in the following section).
16.2 SERIAL COMMANDS FOR MANAGING THE ALIBI MEMORY:
!! IMPORTANT !!
If the serial commands are transmitted in the format:
<ESC> command <STX>
in which: <ESC> is the ASCII decimal 27 character
<STX> is the ASCII decimal 02 character
Also the relative answer will be:
<ESC> string <STX>
16.2.1 REQUEST WEIGHT VALUE WITH WEIGH ID
The command which allows saving the weight in the alibi memory and the transmission is:
<II>PID<CRLF>
< II > = machine code, only if functioning in 485
PID = saving command of the weight data in the alibi memory
CR = ASCII 13 decimal code
LF = ASCII 10 decimal code
If the gross weight is equal or greater than zero and stable, the instrument will save the current weight in the alibi memory.
And the PID string (weight/id) will be transmitted on the PC port; this is described in the following section.
