Configuration / device parameters
Leuze electronic GmbH + Co. KG
BPS 8
57
Min./max. measurement length parameter
With this parameter, a working limit on the bar code tape can be defined. The BPS 8 outputs position
values within these minimum and maximum limits. Outside of this limit, a position value of zero is output.
Measurement error tolerance parameter
The measurement error tolerance function is used to configure a time which results in an extended output
of the last position value in the event of an error. If the position value changes momentarily to zero, e.g.
due to a brief interruption of the scanning beam, soiling of the bar code tape or other short-term distur
-
bances, the BPS 8 transmits the last valid position value.
If the error disappears within the configured time, the control notices nothing. The availability of the system
is thereby ensured. No new values are delivered by the BPS 8, however, for a period of time extending up
to the configured tolerance time. With the Delay error output parameter, an integration error (corresponds
to a missing position value) can be signaled immediately or after the tolerance time has elapsed. If the
error persists after the tolerance time has elapsed, the last valid position value is output.
