Chapter 2 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.
