4.5 Factor Groups (fg) (DS402)
4.5.1 General Information
4.5.1.1 Factors
There is a possibility to convert between physical dimensions and sizes, and the internal units used
in the device (increments). Several factors can be implemented. This chapter describes how these
factors influence the system, how they are calculated and which data are necessary to build them.
Normalized parameters are denoted by an asterisk *.
4.5.1.2 Relationship between physical and internal units
The factors defined in the factor group set up a relationship between device-internal units (incre-
ments) and physical units.
The factors are the result of the calculation of two parameters called dimension index and notation
index. The dimension index indicates the physical dimension, the notation index indicates the physi-
cal unit and a decimal exponent for the values. These factors are directly used to normalize the phy-
sical values.
The notation index can be used in two ways:
l For a unit with decimal scaling and notation index < 64, the notation index defines the expo-
nent/decimal place of the unit.
l For a unit with non-decimal scaling and notation index > 64, the notation index defines the
sub-index of the physical dimension of the unit.
