负载分配是Profibus上使用的分辨率。负荷分配值为由PFEA112计算，取决于设定的测量范围。
测量范围在2001-5000范围内划分为有限数量的分区。
负载分割值=一个分割，仅包含一个有效数字（1、2或5）。
Profibus最多可处理–32768至+32767（216）个分区。
示例1：a、 Profibus测量范围（由用户设置）=15 500 N（正常运行期间预计的腹板张力）
b、 PFEA112计算的负荷分配=5 N（Profibus上最低有效位的值）
HONEYWELL 05701-A-0325自动化卡件c、 Profibus测量范围/负载划分=15500/5=3100（测量范围分为3100个分区）
示例2：如果示例1中的负载分配5 N不够，则可以调整负载分配。可通过将“杂项”菜单中的“测量范围”（MeasurengRange）设置为提供足够负载划分（分辨率）的值。
a、 测量范围=9000 N（测量范围上的新的较低设置）
b、 PFEA112计算的新负荷分配=2 N（Profibus上最低有效位的新值）
PFEA112中的设定值为9000 N时，Profibus测量范围为0–15500 N（分为7750个分区）仍然可以使用，现在负载分区（分辨率）为2 N。通常，无需将测量范围设置为低于估计腹板的1/3正常运行期间的张力。
对于给定的负载分配，可通过Profibus传输的最大值为：–最大值=荷载分区x 32767
用户更改测量范围值后，唯一的方法是返回默认缩放，是指在杂项菜单。
3.13.5.3 Profibus测量值过滤“值1”具有与电压输出相同的滤波。
“值2”具有与当前输出相同的过滤。
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.
