Default Scaling
Load Cell Combination, LoadCellComb: One or two rolls
SW 1.0-1.7 differs slightly from SW1.8 and later. The difference signal in SW1.0-1.7 has a
different scaling factor as illustrated in Table 3-6. In SW1.8 or later, all signals for each
measurement object have the same scaling. When replacing an older unit with an SW1.8 or later
-unit the load scaling for difference signals must be adjusted in the Profibus master.
Load Cell Combination, LoadCellComb: Segmented roll
As Table 3-6 illustrates the load scaling must be adjusted in the Profibus master when replacing
an old unit with SW1.8 or later -unit.. In the case of 9-12 load cells the scaling is the same for all
SW.
Table 3-6. Scaling of Profibus Measurement Values
Example for 1 kN load cells (SW1.8):
With 1 kN load cells, and with AI1+A+B (AI1 + 2 load cells) connected to the AO 1, the value
of the least significant bit is:
0.001  12  1000 = 12 N
Measuring range: 60 000 N

Section 3.13.5 Handling of Measurement Data through Profibus
3BSE029382R0101 Rev C 3-45
User Defined Scaling
The Profibus Measuring Range and Load Division can be adjusted according to user
preferences.
Profibus Measuring Range
Profibus Measuring Range (estimated web tension during normal operation) is a parameter
entered by the user. After the user has changed the Measuring Range value, changing Load cell
nominal load does not affect the Profibus scaling. The value of the least significant bit is defined
as Load Division.
Load Division
Load Division is the resolution that will be used on Profibus. The Load Division value is
calculated by PFEA113 and depends on the set measuring range.
The measuring range is divided into a limited number of divisions in the range 2001 - 5000.
The Load Division value = one division, contains only one significant digit (1, 2 or 5).
The Profibus can handle max. –32768 to +32767 (216) divisions.
Example 1:
a. Profibus Measuring Range (set by user) = 15 500 N
(estimated web tension during normal operation)
b. Load Division calculated by PFEA113 = 5
