In the overrange area, the current slope of the characteristic curve is maintained when leaving the
linearized nominal range.
Analog value representation of analog input module 466-8MC11
The 466-8MC11 analog input module stores each analog value in a single byte. The other analog
input modules store the analog values in words (see Table 11-4).
