R/W
Plausibility counter decrement setting. Number of counts to
be decreased on the plausibility counter when the actual
measured value is within the error limits (Fct. C1.4.2).

R/W
Limit setting for the plausibility counter. When this limit is
reached, the measured value will not be discarded when it
exceeds the error limit (Fct. C1.4.3).

In percentage of the measured value. If the measured value
exceeds this limit compared to the previous measured value,
the measured value will be discarded and the plausibility
