Module Operation
Count Range
In a non-inverted count range, the outputs are active if the count value is within
the user-defined range. In an inverted count range, the outputs are active if the
count value is outside the user-defined range. Valid limits for the range are
-2…2 billion regardless of programmed minimum and maximum values.
Figure 9 shows all ranges referring to one counter. The module is capable of
individually assigning each range to any counter. Each counter can also have a
combination of count and rate ranges.
