In the following there are the measuring ranges with corresponding 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.
