8.1.7.19 Module 18: Measuring error tolerance
Description
The measuring error tolerance function is used to configure a time which results in an
extended output of the last position value (module 1) in the event of an error. If the position
value changes momentarily to zero, e.g. due to a brief interruption of the laser beam, soiling
of the barcode tape or other short-term disturbances, the BPS transmits the last valid posi-
tion value.
If the error disappears within the configured time, the control notices nothing or only a small
change in the position value. The availability of the system is thereby ensured. No new
values are delivered by the BPS 34, however, for a period of time extending up to the config-
ured tolerance time. With the "delay error output" parameter, an integration error (corre-
sponds to a missing position value) can be signalled immediately or after the tolerance time
has elapsed. If the error persists after the tolerance time has elapsed, a position value of
zero is output.
