Deadband supervision
The deadband supervision function reports the measured value according to
integrated changes over a time period. In
Figure 804
the values are reported at
points Y1, Y2, Y3 and Y4. There is no value report at the end of |A3 + A4 + A5 + A6
+ A7| because the positive and negative areas counteract each other. The integrated
changes, |A3 + A4 + A5 + A6 + A7|, equal approximately zero.
