Actual values for the ABB Drives profile and DCU Profile

The ABB Drives profile supports the use of two fieldbus actual values, ACT1 and
ACT2. The actual values are 16-bit words each containing a sign bit and a 15-bit
integer. A negative value is formed by calculating the two's complement from the
corresponding positive value.
The actual values are scaled as defined by parameters 46.01...46.04; which scaling
is in use depends on the setting of parameters
act2 type (see page 337).
