Table 7-1: List of Target Object Properties
Property
|
Description
|
Write
|
Connected
|
Communication status between the host PC and the target PC. Values are 'Yes' or 'No'.
|
|
Application
|
Name of the Simulink model and target application build from that model.
|
|
Mode
|
Type of Real-Time Workshop code generation. Values are 'Real-Time Singletasking', 'Real-Time Multitasking', or 'Accelerate'. The default value is 'Real-Time Singletasking'.
|
|
|
Note Even if you select Real-Time Multitasking, the actual mode can be Real-Time Singletasking. This happens if your model contains only one or two tasks and the sample rates are equal.
|
|
Status
|
Execution status of your target application. Values are 'stopped' or 'running'.
|
|
CPUoverload
|
CPU status for overload. If the target application requires more CPU time than the sample time of the model, this value is set from 'none' to 'detected' and the current run is stopped. Correcting CPUoverload requires either a faster processor or a larger sample time.
|
|
ExecTime
|
Execution Time. Time, seconds, since your target application started running. When the target application stops, the total execution time is displayed.
|
|
SessionTime
|
Time since the kernel started running on your target PC. This is also the elapsed time since you booted the target PC. Values are in seconds.
|
|
StopTime
|
Time when the target application stops running. Values are in seconds. The original value is set in the Simulink Simulation Parameters dialog box.
When the ExecutionTime reaches the StopTime, the application stops running.
|
Yes
|
SampleTime
|
Time between samples. This value equals the step size, in seconds, for updating the model equations and post the outputs.
|
Yes
|
AvgTET
|
Average task execution time. This value is an average of the measured CPU times, in seconds, to run the model equations and post outputs during each sample interval. Task execution time is nearly constant with minor deviations due to cache, memory access, interrupt latency, and multirate model execution.
|
|
MinTET
|
Minimum task execution time. Corresponds to the fastest time (smallest time measured), in seconds, to update model equations and post outputs.
|
|
MaxTET
|
Maximum task execution time. Corresponds to the slowest time (longest time measured), in seconds, to update model equations and post outputs.
|
|
ViewMode
|
Displays either all scopes or a single scope on the target PC. Values are 'all' or a single scope index. This property is active only if the environemnt property TargetScope is set to enabled.
|
Yes
|
TimeLog
|
Storage in the MATLAB workspace for the time or t-vector logged during execution of the target application.
|
|
StateLog
|
Storage in the MATLAB workspace for the state or x-vector logged during execution of the target application.
|
|
OutputLog
|
Storage in the MATLAB workspace for the output, or y-vector logged during execution of the target application.
|
|
TETLog
|
Storage in the MATLAB workspace for a vector containing task execution times during execution of the target application.
To enable logging of the TET, you need to check the Log Task Execution Time box located at Simulation Parameters dialog box> Real-Time Workshop page > Category:xPC Target code generation options group
|
|
MaxLogSamples
|
Maximum number of samples for each logged signal within the circular buffers for TimeLog, StateLog, OutputLog, and TETLog. StateLog and OutputLog can have one or more signals.
This value is calculated by dividing the Signal Logging Buffer Size by the number of logged signals. The Signal Logging Buffer Size box is located at Simulation Parameters dialog box> Real-Time Workshop page > Category:xPC Target code generation options group.
|
|
NumLogWraps
|
The number of times the circular buffer wrapped. The buffer wraps each time the number of samples exceeds MaxLogSamples.
|
|
LogMode
|
Controls which data points are logged.
Equi-distant time. Logs a data point at every time interval. Set value to 'normal'.
Equi-distant amplitude. Logs a data point only when one of the output values from the OutputLog changes by a specified amplitude. Set value to a signal value.
|
Yes
|
Scopes
|
List of index numbers with one index for each scope.
|
|
NumSignals
|
The number of signals from your Simulink model that are available to be viewed with a scope.
|
|
ShowSignals
|
Flag set to view or hide the list of signals from your Simulink blocks. This list is shown when you display the properties for a target object. Values are 'on' or 'off'.
|
Yes
|
Signals
|
List of viewable signals. This list is visible only when ShowSignals is set to 'on'.
Property name. S0, S1. . .
Property value. Value of the signal
Block Name. Name of the Simulink block the signal is from.
|
|
S#
|
Property name for a signal.
|
|
NumParameters
|
The number of parameters from your Simulink model that you can tune or change.
|
|
ShowParameters
|
Flag set to view or hide the list of parameters from your Simulink blocks. This list is shown when you display the properties for a target object. Values are 'on' or 'off'.
|
Yes
|
Parameters
|
List of tunable parameters. This list is visible only when ShowParameters is set to 'on'.
Property name. P0, P1. . .
Property value. Value of the parameter in a Simulink block.
Type. Datatype of the parameter. Always double.
Size. Size of the the parameter. For example, scalar, 1x2 vector, or 2x3 matrix.
Parameter name. Name of a parameter in a Simulink block.
Block name. Name of a Simulink block
|
Yes
|
P#
|
Property name for block parameter.
