Building Simevents model with Matlab code. Setting the output switch 'number of ports' parameter.

Hello, I am trying to build a simevents model using matlab code since it's a big and complex model and is more accurate and quicker to proceed this way.

I am having a problem setting the parameter for the entity output switch regarding the number of ports. When i call the parameter 'ports' in the add_block command, the system returns an error saying that this parameter is read only.

Do you know any way I could get around this?

this is what I m writing:

add_block('built-in/entityoutputswitch',[sys '/os'],'Position',pos,'outputports','70')

and this is what I get:

Error using model (line 53)

EntityOutputSwitch block parameter 'OutputPorts' is read-only

Hi Marco,

If you are trying to set the 'Number of output ports', have you tried the following instead:

add_block('built-in/entityoutputswitch',[sys '/os'],'Position',pos,'NumberOutputPorts','70')

You can see all the dialog parameters available for the block using the following:

>> get_param(gcb, 'DialogParameters')

ans = 

  struct with fields:

       NumberOutputPorts: [1×1 struct]
      SwitchingCriterion: [1×1 struct]
                    Seed: [1×1 struct]
     SwitchAttributeName: [1×1 struct]
    InitialPortSelection: [1×1 struct]
