In the case of pulse counter with external direction control,
device inputs I1 through I4 must be used as pulse inputs and
device inputs I5 through I8 must be used as direction inputs.
In the case of counters with 2 counter inputs, I1 through I4
should be used with first priority.
In the case of incremental encounters, I1 through I4 should be
used with first priority.
In the case of incremental counters, channel A and channel B
must deliver pulses with an offset of 90°.
