Set VariableTable object for block

Since R2024a

Syntax

simscape.instrumentation.setVariableTable(blockName,VariableTable)

Description

simscape.instrumentation.setVariableTable(blockName,VariableTable) sets the variable table, VariableTable, for the block, blockName. The variable table can by empty or it can have variables selected for logging. To log the variables, enable logging for the block.

Set VariableTable Object for Block

This example shows how to set the simscape.instrumentation.VariableTable object for the Ideal Torque Source block in the Permanent Magnet DC Motor example model.

To open the model, enter:

openExample('simscape/PermanentMagnetDCMotorExample')

To get the default variable table for the Load Torque block, enter:

table1 = simscape.instrumentation.defaultVariableTable('PermanentMagnetDCMotor/Load Torque')

table1 = 

VariableTable (string ⟼ VariableConfiguration) with 5 variable(s):
 
                Name       Unit     Logging
              _________    _____    _______

    C.w ⟼    <missing>    rad/s     false 
    R.w ⟼    <missing>    rad/s     false 
    S   ⟼    <missing>    N*m       false 
    t   ⟼    <missing>    N*m       false 
    w   ⟼    <missing>    rad/s     false

To change the logging status of the t variable, enter:

table1("t").Logging = true

table1 = 

VariableTable (string ⟼ VariableConfiguration) with 5 variable(s):
 
                Name       Unit     Logging
              _________    _____    _______

    C.w ⟼    <missing>    rad/s     false 
    R.w ⟼    <missing>    rad/s     false 
    S   ⟼    <missing>    N*m       false 
    t   ⟼    <missing>    N*m       true  
    w   ⟼    <missing>    rad/s     false

To set table1 as the variable table for the Load Torque block, enter:

simscape.instrumentation.setVariableTable('PermanentMagnetDCMotor/Load Torque',table1)

To confirm that you properly set the variable table as table1, confirm that the logging status for t is true. Enter:

simscape.instrumentation.getVariableTable('PermanentMagnetDCMotor/Load Torque')

ans = 

VariableTable (string ⟼ VariableConfiguration) with 5 variable(s):
 
                Name       Unit     Logging
              _________    _____    _______

    C.w ⟼    <missing>    rad/s     false 
    R.w ⟼    <missing>    rad/s     false 
    S   ⟼    <missing>    N*m       false 
    t   ⟼    <missing>    N*m       true  
    w   ⟼    <missing>    rad/s     false
