4-3 Data Format
Example 4.3.2 :
• If the output range is set as 4 to 20 mA
• The desired analog output current is 10 mA
The data value should be : 037.50<CR>
(10 mA - 4 mA ) / (20 mA - 4mA) = 37.50 %
4. 4. Hexdecimal Format
The data is in hexdecimal format as the bit 1 and 0 are set as ‘10’.
The data string length is 3 characters. It is equivilant to 12 binary
bits. Because the output of ND-6021 is unipolar, the maximum
value of the digits is FFF(H) and the minimum value of the digits
is 000(H).
As the output range is set to 0~20mA, the value ‘FFF(H)’
represents 20mA and ‘000(H)’ represents 0mA. Similarily, as the
output range is set to 4~20mA, the value ‘FFF(H)’ represents
20mA and ‘000(H)’ represents 4mA.
Example 4.3.1 :
• If the output range is set as 0 to 20 mA
• The desired analog output current is 10 mA
Two’s complement hexdecimal : 7FF<CR>
