MATLAB: Simulink: Access bus element properties

bus element propertiessimulink

How to access one bus element properties (minimum and maximum values) in Simulink ? I would like to use these values to saturate a computed signal before assigning the signal.
Thanks

Here is one approach that might work. It requires some knowledge of block masking.
  1. Create a subsystem. Inside the subsystem, place a constant block connected to an output port. Set the value of the constant block to be "K"
  2. Mask the subsystem
  3. Edit the subsystem mask. Add 3 "Edit" parameters. 1 for the bus name, the second for the bus element name. The third should have the name "K" and uncheck the "Visible" box.
  4. On the mask "Initialization", add code that:
  5. Creates an instance of the bus specified in the first parameter
  6. Searches the bus to find the bus element specified by the second parameter
  7. Sets the workspace mask variable "K" created in step 3 to be the min or max value of the bus element
