The variable list pane, on the left side of the Real-Time Viewer form, lists all variables in the RTDB of the currently running test. It updates dynamically when different tests are run. The points are arranged in three tabs.
I/O points are variables that are created in the points forms of the Control Center. They can be mapped to hardware channels or message fields. See Mapping I/O Points to Hardware. I/O point names with periods in them are presented hierarchically.
Parameters and Signals are variables defined by the models. These names have forward slashes in them and are also presented hierarchically. The top level of the hierarchy of a variable is the name of the instance of the model the variable is from.
Multiple variables may be selected from the tables using control-click and shift-click, but selections may only be made from one tab at a time. The most recently clicked-on variable is displayed in the form at the top of the Get/Set Value tab. See Get/Set Value Tab (Upper Right Pane).
Expand All 
Expands the hierarchy tree for all variable names in the variable list tables. I/O Point names with periods or parameter and signal names with forward slashes in the names are hierarchical names and are displayed as a tree. For example, A.ai000 and A.ai001 would display ai000 and ai001 as children of the A node.
Collapse All 
Collapses the hierarchy tree for all point names in the point table to show just the top level nodes.
Filter
Displays in the variable tables only variables whose name matches the regular expression. See Regular Expressions.
I/O Points Tab
I/O Point Name Column
Name of the I/O point.
C Type Column
C language type of the I/O point. Tables will have their dimensions specified in square brackets after the C type.
Type Column
Abbreviation of the kind of point this is. The first letter indicates whether it is Analog, Digital, or String. The subsequent letters indicate Input, Output, or Input/Output.
Description Column
Description of the point.
Parameters Tab
Parameter Name
Name of the parameter.
Value
Value of the parameter.
C Type
C language type of the parameter. Tables will have their dimensions specified in square brackets after the C type.
Signals Tab
Signal Name:
Name of the signal.
C Type
C language type of the signal. Tables will have their dimensions specified in square brackets after the C type.
Adds charts to the Real-Time Charts window that plot the value of the selected variables against time. See Real-Time Charts.
Add to Table
Adds the selected variables to the table of variables whose values are displayed and updated in real time in the Get/Set Value tab (the refresh list). See Get/Set Value Tab (Upper Right Pane).
If a test session has the Scheduling Stats turned on (see Logging: Scheduling Stats), additional pseudo-variables will be in the I/O Points tab that allow the Real-Time Viewer to graph the start time, run time, and maximum run time.
