The parameter data may be accessed during runtime with the following
record sets:

No. Byte
Meaning Default
128 0 Function-number channel 0 10h
129 0 Function-number channel 1 10h
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.
