MATLAB: What is the difference b/w “Bus Editor” and “Bus-creator” in simulink

bus creatorsimulink

* can anyone tell me the difference b/w "Bus Editor" and "Bus-creator"?

basically i want to create a bus with some set of signals and send those to output port after processing. as per my knowledge, i can do this two way : a) create a bus using bus editor and develop a simulink model for processing b) otherwise develop a simulink model and drag "bus creator" block which creates a bus and process with that*

You are little bit confused.

Bus Creator is the simulink block which takes many input signals and generate bus as output.

Bus Editor is the GUI utility used to define the Bus objects and their property. Bus objects are simulink objects (just like variables and parameters which are used to set bus property from base workspace.

In your case, drag a bus block from library. Double click on it and set the number of signals and signal names in dialog box.

But, If you don't want to use the settings from dialog box, check on "Specify properties via bus object", enter the name of bus object and click on "edit" button to open and configure a bus object. This object will appear at matlab's base workspace as "Simulink.Bus" object. You can also create & configure this bus object programmically without bus editor.

MATLAB: How to have a Bus Selector block accept signal from an Inport block in a subsystem in Simulink

In order to create and build a subsystem, which has an Inport block feeding into a Bus Selector block, perform the following steps:

1. Double click on the Inport Block to view the Block Properties. Click on the Signal Specification tab and check ‘Specify properties via bus object’. Keep the default name as ‘BusObject’. You will have to do this for the Inport blocks at the root level and also within the subsystem.

2. Create the bus object, BusObject, by using the Bus Editor. To create the bus object and edit its properties execute the following code at the MATLAB command prompt:

BusObject = Simulink.Bus
buseditor

In the resulting window, the Bus Editor, add the signals that the input bus will have with the appropriate names. Verify that the change has been saved by typing ‘BusObject’ at the prompt.

3. You should now be able to right click on the system and build it by selecting Real-Time Workshop from the menu.

MATLAB: Can’t I propagate the bus signals through a Switch block

"Switch" blocks support bus signals, however there is a limitation: Hierarchies and element names of both bus inputs must be identical.

You have two options to resolve this error:

1. Rename the input signals to the "Bus Creator" block so that they match the Bus definition (you may have to do this for both "Bus Creator" blocks)

2. Un-check the following "Bus Creator" block parameter ("checked" by default):

Un-checking the parameter will strictly enforce the output signal names to match the bus definition, regardless of the input signal names.
