Recommendation If you are not certain that the scan data can be processed at the speed at which they are
output by the LMS, you should only request the scan data for a single scan. The scan
counter in the measured value output can be used as an indication that processing is too
slow (see
section 10.2.4 “Read scan data” on page 80 ).
