Specifications

4-2 Data Format
Example 4.2.1:
• If the output range is set as 0 to 20 mA
• The desired analog output value is +5.678 mA
The data value should be : 05.678<CR>
Example 4.2.2:
• If the output range is set as 0 to 10 V
• The desired analog output value is +2.345 V
The data value should be : 02.345<CR>
4. 3. Percent of FSR
The date is in percent of FSR(Full Scale Range) when the bit 1
and 0 of the configuration register are ‘01’. The data string is
composited by 6 characters. Because the output of ND-6021 is
unipolar, the value is always positive.
The value is unit-less and depends on the output range setting
too.
• Set bit 1 and bit 0 of data format variable to “01” means the
data is represented in percent of FSR.
• Data string is fixed length of 6 characters. The value is
composed of five decimal digits with a decimal fixed point.
• Three digits present the integer part and two digits present
the fraction
• Maximum resolution is 0.2%.
Example 4.3.1 :
• If the output range is set as 0 to 20 mA
• The desired analog output current is 10 mA
The data value should be : 050.00<CR>
10 mA / 20 mA = 50.00 %
