In the following there are the measuring ranges with function number listed, which were
supported by the analog module. With FFh the corresponding channel is deactivated. The
formulas listed here allow you to transform an evaluated measuring value (digital value)
to a value assigned to the measuring range (analog value) and vice versa.

For each channel an
upper
and a
lower limit
may be defined. Here only values of the
nominal range may be preset, otherwise you receive a parameterization error. By preset-
ting 7FFFh for the upper respectively 8000h for the lower limit value the corresponding
limit is deactivated. As soon as the measuring value is beyond the limits and the limit
value monitoring is activated, a process interrupt is initialized.
