Note
The default values of the device options are stored in non-volatile memory. The default values can be overruled during
operation. However, at power-on the default values are restored and the smart sensor will start up with the default
values stored in the non-volatile memory.

Parameter
R/W Def.
Mode Description
24 to 34 Factory use only
A.8 Read write holding registers
Register 34
IO_DEF_SCALE_FACTOR
The default scale factor is set in the factory mode or service mode and is stored in non-volatile memory. The default scale factor
stored in non-volatile memory is always set after a power-on. However it is possible to change the default setting during opera-
tion by writing a value to the register 34.
Note
This value is not stored in non-volatile memory and is overwritten with the default value at power on.
The following values are valid:
Scale factor = 2
Scale factor = 1
Scale factor = 0
Scale factor = -1
Scale factor 0 is the default value. See also input register 4
IO_SCALE_FACTOR.
A.9 Read discrete inputs
Discrete input 0 IO_FALSE
This discrete input is always false
Discrete input 1 IO_TRUE
This discrete input is always true
Discrete input 2 IO_VOID_DATA_FLAG
The void data flag is raised when the data in register
IO_SENSOR1_DATA or IO_RAW_SENSOR1_DATA is not valid, because the
body temperature of the sensor is too low or too high, when there is an internal overflow condition, because a calculation is out
of range or a division by zero occurred, the reference voltage of the ADC is not stable or the digital filter is not stable. When the
IO_VOID_DATA_FLAG is set, bit 0 in the IO_STATUS_FLAGS is also set.
