RTC Window Editor - Table Pane

A table allows you to translate measured input values from the control point to new output values. The input values can be the output from a Range, Table or Variable. You can define a table within the Global section or in regulator definitions.

The only limit to the number of tables you can define is the amount of computer memory available.

The Table pane contains the following fields:

Name

A label that uniquely identifies the table

Measurement

The type of output data to be used as a regulator setting or controller setpoint.

Input Range

The name of a previously defined Range, Table or Variable. The input range defines the control point at which input values are measured.

Type

Options are:

  • Linear - InfoWorks uses linear interpolation between the defined Output values in the Table data Grid. InfoWorks linearly extrapolates from the first two values if the input value is less than the first table entry, or from the last two values if the input value is greater than the last table entry.
  • Step - no interpolation is applied to the Output values

Table Data Grid

Define the table data here. Enter Input values in ascending order. Enter a corresponding Output value for each Input value.

The number of records in a table is only limited by the available memory.

Input

Input value

If the input range is a Time or Time Repeat range, you enter values here as a date and time (dd/mm/yy-hh:mm).

  • For a daily range, enter the time (hh:mm) and leave day, month and year as zero.
  • For a weekly range, enter the time (hh:mm) and day (dd). Enter 01 for Monday, 02 for Tuesday and so on. Sunday is 07. Leave month and year as zero.

Output

Corresponding output value. This will be used as a regulator setting or a controller setpoint.

For an example of how the Table pane is used in a RTC, see RTC Table Example.
