INPUT STATUS BYTES TABLE
The Modbus address 40008 is composed by 2 bytes. The conversion of these 2 bytes from hex into
binary gives the meaning of each single bit described in this table.

E.g. if the bytes in the address 40008 are 64 85, the conversion into binary gives the sequence of
bits 110010010000101.
The digit at the right hand side matches with the 1st bit (Net weight polarity), therefore the values
given in the above mentioned example are equivalent to:
• Net weight polarity= 1 = negative
• Gross weight polarity= 0 = positive
• Weight stability= 1 = yes
• Millivolt polarity= 0 = positive
• Underload condition= 0 = no
• Overload condition= 0 = no
• Off range condition= 0 = no
• Preset tare condition= 1 = yes
• Input 1 and 2= 0= de-activated
• Relay output 1 status= 1 = activated
• Relay output 2 status= 0 = de-activated
• Scale unloaded (ZB)= 0 = no
• Keyboard status= 1 = locked
• Scale unloaded (ZC)=
(*) Bit of empty scale “ZB” related to a new Zero Scale obtained with the
0
key (see page 12).
The balance is considered empty when the weight is in the range “0 Band” (see page 26).
(**) The keyboard is considered locked when they are all the keys on the front panel (see page 15).
(***) Bit of empty scale “ZC” related to the Zero Calibration (see page 23). This bit does not follow
the Zero Scale obtained with the
0
key but remains related to the original Zero Calibration. The
balance is considered empty when the weight is in the range “0 Band” (see page 26)
