Range Check

The “Range check” offers the possibility to check if a value of the signal is within a certain range. It is possible to specify a substitute value if the limit value / allowed range is violated.

Configuration

Signal Name

The name of the signal at the ‘in’ port.

Min (optional)

The minimum value allowed (\(x \geq min\)) (not checked if empty). The value can be a floating point value or a signal expression ({signalName}).

Max (optional)

The maximum allowed value (\(x \leq max\)) (not checked if empty). The value can be a floating point value or a signal expression ({signalName}).

Interval (optional)

The mathematical specification of the allowed ranges.

Example 1:

Signal lowerLimit=3

[{lowerLimit},10]

\(3 \leq x \leq 10\)

Example 2:

[5,10];]100,300]

\(5 \leq x \leq 10 \lor 100 < x \leq 300\)

see interval

Replacement Type

Options:

• None No replacement will be made.

• Value The current value will be replaced by the ‘Replacement Value’.

• Violated Limit The current value will be replaced with the violated limit.

  Example:

  The upper limit 1000 has been violated. The replacement value will be 1000.

  Warning

  This option can only be used, if the range check does not use Interval.

Replacement Value (optional)

The value to replace when a limit is violated (used only if Replacement Type is Value). The value can be a floating point number or a signal expression ({signalName}).

Reset Flags

If true the violation flags (UpperLimitViolated,LowerLimitViolated) are reset.

Reset Quality

Normally the quality of the value automatically becomes bad if the allowed range is violated. If this value is set to true, the original quality is preserved.
