Transport layer

Description

Specify the transport protocol for communications.

Category: Code Generation > Interface

Settings

Default: tcpip

tcpip: Use a TCP/IP transport mechanism. Selecting this parameter sets parameter MEX-file name to ext_comm.
serial: Use a serial transport mechanism. Selecting this parameter sets parameter MEX-file name to ext_serial_win32_comm.
XCP on TCP/IP: Use XCP protocol with TCP/IP transport layer. Selecting this parameter sets parameter MEX-file name to ext_xcp.
XCP on Serial: Use XCP protocol with serial transport layer. Selecting this parameter sets parameter MEX-file name to ext_xcp.
customTransportLayer: Use custom transport layer.

Tips

The Configuration Parameters dialog box displays parameter MEX-file name next to Transport layer. You cannot edit the value for MEX-file name. The value is specified either in matlabroot/toolbox/simulink/simulink/extmode_transports.m for targets provided by MathWorks^®, or in an sl_customization.m file for custom targets and transport mechanisms.

The command-line parameter is an index. To get the transport layer index, use these commands:

cs = getActiveConfigSet(modelName);
index = Simulink.ExtMode.Transports.getExtModeTransportIndex(cs, transportLayer);

transportLayer is one of these values:

'tcpip'
'serial'
'XCP on TCP/IP'
'XCP on Serial'
customTransportLayer

To select the transport layer:

set_param(cs, 'ExtModeTransport', index)

To determine the transport layer:

transportLayerName = Simulink.ExtMode.Transports.getExtModeTransport(cs, index)

Dependency

Selecting parameter External mode enables this parameter.
