8.3 High-Speed Counter Function

The high-speed counter function counts the input signals and sets the desired output to TRUE
or to FALSE when the target value is reached. The high-speed counter function can also be
used for cam control and for input pulse measurement.
Setting the system registers
In order to use the high-speed counter function, it is necessary to set the inputs in the system
