UNITS

defines whether physical units or internal bits are used.  This variable is relevant mainly for Current, Velocity, Acceleration and Analog Input variables, in order to allow more precise definitions while using the internal bits of the Integer variables.  It is recommended that most users use the physical units.
 0 = use physical units
 1 = use internal units
The descriptions in this guide use the physical units.  Variables that may be defined using internal units are listed in the following table, along with their internal unit ranges and units.
