Offset value
The offset value is calculated by the preset function and shifts the
position value by the calculated value.
The offset value is stored in the device and can be provided by
the diagnostic octets 32 to 35. The data type for the offset value
is a 32-bit binary value with sign, whereby the offset value range
is equal to the measuring range of the device. The preset function
is used after the scaling function. This means that the offset value
is indicated according to the scaled resolution of the device.

Offset value of the encoder manufacturer
The manufacturer offset value indicates the encoder offset set by
the manufacturer. This value gives information on the shift of the
position zero point in number of positions from the physical zero
point of the encoder. The data type for the offset value is a 32-bit
binary value with sign. The value range corresponds to the
measuring range of the encoder. The offset value of the
manufacturer of the encoder is indicated in the number of units
according to the basic resolution of the encoder. The value is
stored in write-protected memory, which can be changed only by
the encoder manufacturer. This value has practically no
importance for the user.
