Limit values
The CSP2008 can check the result of the measurement or calculation against definable
limit values. Inadmissible deviations can thus be detected and sorting criteria can be
realised.
The limit values are
- upper and lower limit (UL, LL),
- upper and lower warning (UW, LW).
The OK signal is derived from the upper and lower limit values.

Fig. 30 Parameters for the limit value consideration of "Absolute" and "Relative" attributes
If the signal or the calculation result is within the range of a limit value, this can result in
repeated activation or deactivation of the digital output. "Flickering" of the digital outputs
is prevented by specifying a
Hysteresis
