Integral deadband supervision
The deadband value used in the integral calculation is configured with the
Value
deadband
setting. The value represents the percentage of the difference between the
maximum and minimum limits in the units of 0.001 percent * seconds. The reporting delay
of the integral algorithms in seconds is calculated with the formula:

Example of X130 (RTD) analog input deadband supervision
Temperature sensor Pt100 is used in the temperature range of 15...180 °C.
Value unit
“Degrees Celsius” is used and the set values
Value minimum
and
Value maximum
are set
to 15 and 180, respectively.
Value deadband = 7500 (7.5% of the total measuring range 165)
AI_VAL# = AI_DB# = 85
If AI_VAL# changes to 90, the reporting delay is:
