Description
The user-defined units are made up of offset (3321
h
). If both object
entries are still set to the default values, the value in 3320
h
is specified in the "ADC digits" unit.
Formula for converting from digits to the respective unit:
•
Voltage input: x digits * 10 V / 1024 digits
•
Current input: x digits * 20 mA / 1024 digits
The following applies for the sub-entries:
