R/W Limit used in square root processing. A value of zero percent
of scale is used in block processing if the transducer value
falls below this limit, in %of scale. This feature may be used to
eliminate noise near zero for a flow sensor.

Mix Allows the transducer analogue input or output to the block to
be manually supplied when "Simulate" is enabled. When
simulation is disabled, the simulate value and status track the
actual value and status.
