D300529 0115 - BL67 I/O modules
8-11
BL67-2AO-I, 0/4 … 20mA
Value representation process automation (NE 43)
 16-bit-representation
The hexadecimal value transmitted by the module has to be interpreted as decimal value, which corre-
sponds, if multiplied with a defined factor, to the analog value.
Example:
Process value:
– dec. 15020
– hex. 3AAC
Output current 15.02 mA
dec. hex. 0 … 20 mA
dec. value = 1000 [1/mA] × current value [mA]
65535 FFFF 22.000 mA
22001 55F1 22.000 mA
