Description
The user units are combined from offset (3321
h
). When both objects are
left to the default settings, the value in 3320
is given in the unint "ADC digits".
Formulars for converting from digits to the particular unig:
Voltage input: x digits * 10 V / 1024 digits
Current input: x digits * 20 mA / 1024 digits
For the sub entries apply:
•
Sub-index 00
h
: Amount of analogue inputs
•
Sub-index 01
h
: Analogue value 1
•
Sub-index 02
h
: Analogue value 2
3321h Analogue Input Offset
Function
Offset that is added to the read-in analog value (3320
) before division with the divider from object
is carried out.
