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

Meaning Default
128 0 Function-number channel 0 10h
129 0 Function-number channel 1 10h
130 0 Function-number channel 2 10h
131 0 Function-number channel 3 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.
