Section 3.6 Product Features
The following sections provide information on user-configurable parameters.
3.6.1
Data Format Description
The data format is used to define the display scale of the measured input data.
Each channel can display different format based on the user selection. This
module provides four options for channel input display:
Index
Data Format
0
Engineering Unit ×1
1
Engineering Unit ×10
2
Raw/Proportional
3
Percentage Full Scale
The maximum range to display a measured input data in the input table is from
-32768 to +32767 as a signed 16-bit integer. The actual range will be scaled to fit
the selected Input Type. For example, the valid range for Type B Thermocouple
is from 300 °C to 182 0°C. In Engineering Unit ×1 format, the valid display
range is from 3000 to 18200 which provides the resolution down to 1 decimal
place. In Engineering Unit ×10 format, the valid display range is from 300 to
1820 as integers. The Raw/Proportional format provides 65 K resolution based
on the valid range in EU×1 format of the selected Input Type. The same scaling
requirement applies to the Percentage format which has 10 k or 10.5 k resolution.
