Algorithm (Workflow)
This function, smbLogOutputPort, is designed to activate data logging for a specific output port of a Simulink block. It is part of the SimMechanics library and was created by Tim Lueth in December 2016.
Input Parameters
- block: The Simulink block for which the output port data logging is to be activated. If this parameter is empty, the function uses the current block (
gcb).
- Nr: The number of the output port that needs to be logged.
- varargin: An optional parameter that can be used to specify a custom signal name for the output port.
Algorithm Steps
- Check if the
block parameter is empty. If it is, set block to the current block using gcb.
- Construct a default signal name using the output port number
Nr with the format 'OutP.%d'.
- If a custom signal name is provided in
varargin, use it instead of the default name.
- Generate a full signal name by combining the block's name (retrieved using
smbWhich(block)) and the signal name.
- Retrieve the port handles of the block using
get_param and the block's name.
- Set the name of the specified output port to the generated full signal name using
set_param.
- Enable data logging for the specified output port using
set_param with the 'DataLogging' parameter set to 'on'.
- Optionally, the function can display the name and data logging status of the output port if no output argument is specified.
