負(fù)載分配是Profibus上使用的分辨率。負(fù)荷分配值為由PFEA112計(jì)算，取決于設(shè)定的測(cè)量范圍。
測(cè)量范圍在2001-5000范圍內(nèi)劃分為有限數(shù)量的分區(qū)。
負(fù)載分割值=一個(gè)分割，僅包含一個(gè)有效數(shù)字（1、2或5）。
Profibus最多可處理–32768至+32767（216）個(gè)分區(qū)。
示例1：a、 Profibus測(cè)量范圍（由用戶設(shè)置）=15 500 N（正常運(yùn)行期間預(yù)計(jì)的腹板張力）
b、 PFEA112計(jì)算的負(fù)荷分配=5 N（Profibus上最低有效位的值）
HONEYWELL 05701-A-0325自動(dòng)化卡件c、 Profibus測(cè)量范圍/負(fù)載劃分=15500/5=3100（測(cè)量范圍分為3100個(gè)分區(qū)）
示例2：如果示例1中的負(fù)載分配5 N不夠，則可以調(diào)整負(fù)載分配?？赏ㄟ^將“雜項(xiàng)”菜單中的“測(cè)量范圍”（MeasurengRange）設(shè)置為提供足夠負(fù)載劃分（分辨率）的值。
a、 測(cè)量范圍=9000 N（測(cè)量范圍上的新的較低設(shè)置）
b、 PFEA112計(jì)算的新負(fù)荷分配=2 N（Profibus上最低有效位的新值）
PFEA112中的設(shè)定值為9000 N時(shí)，Profibus測(cè)量范圍為0–15500 N（分為7750個(gè)分區(qū)）仍然可以使用，現(xiàn)在負(fù)載分區(qū)（分辨率）為2 N。通常，無需將測(cè)量范圍設(shè)置為低于估計(jì)腹板的1/3正常運(yùn)行期間的張力。

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.
