RTC Window Editor - Range Pane

Ranges provide a logical output which is TRUE if the measured variable is within the defined range and FALSE if it is outside the defined range. Variables can be measured at any point in the system; they do not have to be local to a regulator.

For an example of the use of a Range see RTC Range Example.

The Range pane contains the following fields:

Name	A label to identify the range
Type	The Range Type (see below). Using an invalid range type will result in the range being ignored
Location: Node Link Subcatchment Regulator Pump Definition Node/Link	Specifies where measurements are taken for this range. This should match the label of a node or link in the network. If not, the range will be ignored. For a Time (or Time Repeat or Local Clock Time or Local Clock Time Repeat) range this field is ignored. For a Variable range, the choice is a Variable, Table, Range or Logic record defined in the Global section of the RTC Scenario or defined before this range in the current regulator. Any of these record types defined below this range in the list in the left hand pane cannot be used.
Location: Distance Downstream	Only applicable for measurement points in conduits (pipes or channels). The position of the measurement point from the upstream end of a conduit. If a distance greater than the conduit length is given the conduit length will be used. The upstream end is assumed if the value is negative. For the APC range type, use this field to specify the minimum idle time of the pump in seconds. The VAR range type does not use this field. This field is ignored for measurements at nodes and controls (except APC) and for time ranges.
Values: Minimum	Minimum numeric range value. If blank, the value defaults to minus infinity. For an APC range type, the minimum is the maximum idle time
Values: Maximum	Maximum numeric range value. If blank, the value defaults to infinity. For an APC range type, the maximum is the maximum running time for one pump
Time/Date: Minimum	Minimum range time. If blank, the time defaults to the start time of the event. A time range should start on a major timestep
Time/Date: Maximum	Maximum range time. If blank, the time defaults to the end time of the event

Range type

The following range types are available:

T	Time	-	dd/mm/yy-hh:mm
TR	Time Repeat	-	hh:mm
LCT	Local Clock Time, which takes account of daylight saving during a run	-	dd/mm/yy-hh:mm
LCTR	Local Clock Time Repeat, which takes account of daylight saving during a run	-	hh:mm
DQ	Rate of change of flow	Conduit/control	DQ
DY	Rate of change of depth	Conduit/control	DY
