Description 12-bit binary number.
Input Range 0 – 4095.
Scaling Scales 12-bit binary values to the
database block’s EGU range.
Ignores the most significant nibble
(4-bits). Out of range values are
treated as 12-bit values. For
example, 4096 is treated as 0
because the four most significant
bits are ignored.
