Comparison Mode

Example Comparison Mode with Linear Counter
Note 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-calculation of
the Unit Output Pattern. If both the Counters are configured to use no Ranges, the
output patterns for both outputs will be all OFF.
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).
