The encoder is connected to Circular Counter 1. The 15 outputs are controlled by
5 Ranges (Range 0 to 4). An Hysteresis of 20 counts is defined and will be applied
to the Range Limits. The outputs are assigned to the Interrupt Tasks 10 to 39
respectively in the PLC ladder program (i.e. offset is 10). As a result the rising
edge of (Digital) Output O0 is assigned to External Interrupt Task 10, the falling
edge to External Interrupt Task 11 and so on.

The Machine Number of the High-speed Counter Unit is 0. The High-speed Coun-
ter is allocated 40 CIO-words starting from CIO 2000 (n = CIO 2000 + 0 x 10) and
400 DM-words starting from D 20000 (m = D 20000 + 0 x 100). The Range Data
of Counter 1 is stored in EM starting from EM100. To configure the Unit the follow-
ing DM-settings must be made.
