CM35 Counter Module

You can use the scanning rate factor to specify that the counting value does
not change until the stated number of encoder pulses has occurred.
This increases the counting range of the encoder pulses by a multiple of the
scanning rate factor.
Evaluation of the channel--specific scanning rate factors must be enabled
with the
²
scanning rate
²
group bit.
When a counting procedure starts, the scanning rate factor is always started
again. The remaining pulses are not carried over from the previous counting
procedure.
