The TimeSeriesThreshold object varies its state between open and closed depending on the present value for a TimeSeries object.
The TimeSeries to be monitored is specified by the TimeSeries keyword. Trigger levels are determined by the MinOpenLimit and MaxOpenLimit keywords. For the TimeSeriesThreshold to be open, the present value for the TimeSeries must be within the range specified by these two keywords.
The LookAhead and Offset keywords provide additional flexibility:
· If a non‑zero value is specified for the LookAhead keyword, then the present value for the TimeSeries must be within the range specified by the MinOpenLimit and MaxOpenLimit keywords over the entire LookAhead duration, starting from the present time.
· If a non‑zero value is specified for the Offset keyword, then the above rule is modified so that the LookAhead duration begins at the present time plus the offset.
