Note 1. The Counter Output Patterns of Counters which are configured to use no (i.e.
zero) Ranges, are ignored in the AND-calculation of the Unit Output Pattern.
Like this, Counters that you do not want to use, do not influence the AND-cal-
culation of the Unit Output Pattern.
2. In case all Counters are configured without ranges, the Unit Output Pattern will
be zero.
3-5-2 Comparison Mode
If the Unit is configured to control the Outputs in Comparison Mode, this Mode can
be applied to Circular Counters or Linear Counters (refer to 3-2-2
"Circular Coun-
ter" and 3-2-3 "Linear Counter" for more information).
Example Comparison Mode
with Linear Counter
In this example 7 Comparison Values are specified. On reaching a Comparison
Value an Output can be Set or Reset depending on the crossing direction. If the
