PROGRAMMING THE WEIGHT SET POINTS
Master: <Addr> "S" <set1> <set2> ETX <chksum> EOT
DAT 100: <Addr> "S" ACK EOT
REQUEST OF THE PROGRAMMED WEIGHT SET POINTS
Master: <Addr> "R" EOT
DAT 100: <Addr> "R" <set1> <set2> ETX <chksum> EOT
CONTROL OF ACTIVATION OF THE LOGIC OUTPUTS (ONLY FOR PROGRAMMED SET POINTS TO
0).
Master: <Addr> "U" <outputs> EOT
DAT 100: <Addr> "U" ACK EOT
REQUEST OF THE LOGIC INPUTS STATUS
Master: <Addr> "I" EOT
DAT 100: <Addr> "I" <inputs> ETX <chksum> EOT
CONTROL OF THE SET POINTS STORAGE IN PERMANENT MEMORY
Master: <Addr> "E" EOT
DAT 100: <Addr> "E" ACK EOT
In the case of communication error or otherwise unrecognized command from DAT 100, it will respond
with the following string:
DAT 100: <Addr> NAK EOT
FIELDS DESCRIPTION
The double quotes enclose constant characters (observe upper and lower case); the <and> symbols
contain variable numeric fields.
STX (start of text) = 0x02h,
ETX (end of text) = 0x03h,
EOT (end of transmission) = 0x04h,
ACK (acknoledgment) = 0x06h,
NAK (No acknoledgment) = 0x15h.
<Addr> = Serial communication address + 0x80h (i.e., address 2: <Addr> = 0x82h (130 decimal
number).
<status> = character encoded as per the following table (bit = 1 if condition TRUE)
Bit 7 Bit 6 Bit 5
0 0
<gross>, <net>, <peak> = field consisting of 8 ASCII characters with the weight value justified on the
right (no leading zeros, with possible decimal point and negative sign).
Under conditions of overload, the weight field assumes the value: "^^^^^^^^".
Under conditions of underload, the weight field assumes the value: "_ _ _ _ _ _ _ _".
In reading error conditions, the weight field assumes the value: " O-L ".
<set1>, <set2> = field consisting of 6 ASCII characters with the weight value justified on the right.
(without leading zeros, with possible decimal point and negative sign).
