Field
Size
Function
Read data
4 bytes
Data to be read as a binary 32-bit value with
plus or minus sign.
Data type: DINT
Read_Value_Selected
1 byte
Acknowledgment of the transmitted function
number.
WriteActive
1 bit
The function selected with
Write_Value_Select
has been executed once.
This bit is deleted if
Write_Value_Select
is set
to 0.
PowerFail
1 bit
Is set when switching on the device.
Is reset by
ResPower
with transition from 0→1.
CmdBusy
1 bit
The device is busy executing a function (e.g.,
waiting for a standstill for taring)
CmdError
1 bit
The device has interrupted the execution
of a command (e.g.,
standstill
could not be
reached within the defined standstill time).
The error number can be read from "LASTER
ROR", see Chapter
ment information, error byte (read)
.
Tare_Active
1 bit
The scale has been tared.
Cal_Changed
1 bit
The device has been calibrated.
When this bit is 1, the weighing point para
meters (EXPO/UNIT/STEP+FSD) must be read
again.
Set after "Power on" and reset after reading
the FSD.
Test_Active
1 bit
The device executes the ADC test. The read
weight value is not the gross value, but the test
value.
OutOfRange
1 bit
Below zero or above Max (FSD).
Standstill
1 bit
The scale is stable.
InsideZSR
1 bit
The gross weight value is within the zero set
ting range.
