Renaming All Ports on a Connector Node - System Composer

Is there a way in System Composer to rename a single port on a connector "node", and have every port (component port or architecture port) on that node be automatically renamed?

Not through the GUI (only happens when all ports have default names) but you can do it programmatically. You could also create a custom edit-time check to flag it as a discrepancy (and offer a fix button) or a right-click context menu using sl_customizations.

To do it programmatically (Assuming you are using input/output ports. This would need to be adjusted for client/server or physical):

1. Lookup the starting port in the model (component output port)

2. Get connectors from the Connectors property of the port

3. Get destination ports (downstream input ports) from the DestinationPort property of the connector.

3. Set the name of the other ports

https://www.mathworks.com/help/systemcomposer/ref/systemcomposer.arch.componentport.setname.html

Here is the code:

archMdl = systemcomposer.loadModel('MyArchitecture')
port = lookup(archMdl, Path='MyArchitecture/path/to/component:MyPortName')
if port.Connected
    connectedPorts = [port.Connectors.DestinationPort];
    arrayfun(@(connectedPort) setName(connectedPort, port.Name), connectedPorts)
end
