Data and Control Port Defaults

In the event that DataInputPort, ControlInputPort, or DataOutputPort values are not provided in a block data record, then the default values are used as provided by these records. This includes information for data type index, complex signals, direct feed through, and a value for buffer destination ports (e.g., indicator for buffer reuse).

Table A-16: Model.rtw Data and Control Input Port Defaults 

Variable/Record Name	Description
DataInputPortDefaults {	Record for default values of block variables that aren't explicitly written in the block data input port records. The block data input port records only contain nondefault values for the following variables.
DataTypeIdx	0
ComplexSignal	no
FrameData	no
HaveGround	no
SrcHasImportedExternPointer	no
DirectFeedThrough	yes. Only written if the rtwgen option WriteBlockConnections has been specified as on.
BufferDstPort	-1: Default is no output ports are reusing the corresponding input port buffer.
}
ControlInputPortDefaults {	Record for default values of block variables that aren't explicitly written in the block control (enable/trigger) input port records. The block control input port records only contain nondefault values for the following variables.
DataTypeIdx	0
ComplexSignal	no
DirectFeedThrough	yes. Only written if the rtwgen option WriteBlockConnections has been specified as on.
FrameData	no
HaveGround	no
SrcHasImportedExternPointer	no
BufferDstPort	-1: Default is no output ports are reusing the corresponding input port buffer.
}
DataOutputPortDefaults {	Record for default values of block variables that aren't explicitly written in the block data output port records. The block data output port records only contain nondefault values for the following variables.
FrameData	no
Offset	-1
Width	-1
Dimensions	[-1, -1]
