3.7.2 Measuring range
The measuring command may be valid across the entire range, or be limited to a
start and end position (active range).
The measurement can be restricted to a defined measuring range. The
measurement will be triggered only when the position lies within the measuring
range.
If a trigger signal is not received within the measuring range, the measuring
command is canceled and a FB error is indicated at the Technology DB.
For non-modulo axes, the sequence in which the start and end values are specified
is irrelevant. If the initial value is greater than the end value, the two values are
exchanged.
If the start value is greater than the end value in a modulo axis, the validity range is
extended from the start value over the modulo transition of the axis to the end
value.
