Range function
Function description
In the Range function, you can define up to 10 thresholds. A defined reference value is compared
with those thresholds. The output variables indicate the status of each of the ranges, according to
mode.
Binary decoder mode decodes single bits from a numerical value.
Input variables Mode Ranges
Enable
General enabling of the function (digital value ON/OFF)
Reference value
Analogue input signal for the reference value being monitored
Threshold A – (max.) J
Selection of the required range boundaries (thresholds)
Parameters Mode Ranges
Mode
Available for selection: only range, Ranges >= value, Ranges <=
value, Ranges > value, Ranges < value
Function quantity
Select the function quantity. A wide range of function quantities are
available, which are applied together with their unit and their decimal
places.
No. of thresholds
Enter the number of thresholds, up to 10
Diff.on
Diff. off
Start differential for the thresholds
Stop differential for the thresholds
➢ The switching thresholds are each divided into a start differential and a stop differential. If
the value is rising, the start differential applies (threshold + Diff.on); if the value is falling,
the stop differential applies (threshold + Diff. off).
➢ Explanation of the three different modes:
only range mode: Only the status of the range applicable to the value will be switched on.
Ranges >= value mode: The range applicable to the value will be switched on, along with
all ranges above.
Ranges <= value mode: The range applicable to the value will be switched on, along with
all ranges below.
Ranges > value mode: Only the ranges above will be switched on.
Ranges < value mode: Only the ranges below will be switched on.
➢ If Diff. on and Diff. off are set to 0, the thresholds will have no hysteresis. The status will be
switched immediately a range boundary is reached. This setting should not be used for
sensor values (e.g. from temperature sensors). If the value is rising, it must exceed a
threshold in order for the status of the next range up to be switched on; if the value is
falling, it must fall below a threshold in order for the status of the next range down to be
switched on.
Example: Mode: only range
Threshold B = 100
Reference value = 100 with value rising, Status A-B = ON
Reference value = 100 with value falling, Status B-C = ON
