Data Format

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>
