Numerical formats
Analog values are transmitted in a standardized format, with
scale start = 0 ‰ and scale end = 1000 ‰ being used as refe-
rence values. Hence all values possible are within the range 0 to
1000. Negative values cannot occur. The hexadecimal value
assigned to a decimal per mille value is calculated as follows:
Hex value = per mille value * 16 + 32768
Example
The measured value of a channel is 87
°
C (= val) in a
measuring range between −50
°
C (= low) and +150
°
C (= high).
Hex value = (val-low) / (high-low) * 1000 * 16 + 32768 = AAD0H
Example
Speed 1 = 240 mm/h
→
index = 08H (from section “System
parameters”).
transmitted value = index * 16 + 32768 = 8080H
