負載分配是Profibus上使用的分辨率。負荷分配值為由PFEA112計算，取決于設定的測量范圍。
測量范圍在2001-5000范圍內劃分為有限數量的分區。
負載分割值=一個分割，僅包含一個有效數字（1、2或5）。
Profibus最多可處理–32768至+32767（216）個分區。
示例1：a、 Profibus測量范圍（由用戶設置）=15 500 N（正常運行期間預計的腹板張力）
b、 PFEA112計算的負荷分配=5 N（Profibus上最低有效位的值）
HONEYWELL 05701-A-0325自動化卡件c、 Profibus測量范圍/負載劃分=15500/5=3100（測量范圍分為3100個分區）
示例2：如果示例1中的負載分配5 N不夠，則可以調整負載分配?？赏ㄟ^將“雜項”菜單中的“測量范圍”（MeasurengRange）設置為提供足夠負載劃分（分辨率）的值。
a、 測量范圍=9000 N（測量范圍上的新的較低設置）
b、 PFEA112計算的新負荷分配=2 N（Profibus上最低有效位的新值）
PFEA112中的設定值為9000 N時，Profibus測量范圍為0–15500 N（分為7750個分區）仍然可以使用，現在負載分區（分辨率）為2 N。通常，無需將測量范圍設置為低于估計腹板的1/3正常運行期間的張力。
對于給定的負載分配，可通過Profibus傳輸的最大值為：–最大值=荷載分區x 32767
用戶更改測量范圍值后，唯一的方法是返回默認縮放，是指在雜項菜單。

“值2”具有與當前輸出相同的過濾。
Load Division
Load Division is the resolution that will be used on Profibus. The Load Division value is
calculated by PFEA112 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 PFEA112 = 5 N
(value of least significant bit on Profibus)
c. Profibus Measuring Range/Load Division = 15500/5 = 3100
(the measuring range is divided into 3100 divisions)
Example 2:
If the Load Division, 5 N, in Example 1 is not sufficient, the Load Division can be adjusted.
This can be done by setting (decreasing) MeasuringRange in the Miscellaneous Menu to a
value that gives a sufficient Load Division (resolution).
a. Measuring Range = 9000 N
(New, lower setting on measuring range)
b. New Load Division calculated by PFEA112 = 2 N
(New value of least significant bit on Profibus)
With the setting 9000 N in PFEA112 , the Profibus measuring range 0 – 15500 N (divided into
7750 divisions) can still be used, now with the Load Division (resolution) 2 N.
Normally, there is no need to set the measuring range lower than 1/3 of the estimated web
tension during normal operation.
The max. value that can be transmitted via Profibus, for a given Load Division, is:
– Max. value = Load Division x 32767
NOTE
After the user has changed the Measuring Range value, the only way to
return to Default scaling, is to use the function Set Factory default in the
Miscellaneous Menu.
3.13.5.3 Filtering of Profibus Measuring Values
“Value 1” has the same filtering as the voltage output.
“Value 2” has the same filtering as the current output.
