Table A-10: Model.rtw External Inputs and Outputs
Variable/Record Name
|
Description
|
ExternalInputs {
|
|
ExternalInputDefaults {
|
|
RecordType
|
ExternalInput. The record type is used by TLC in general processing of the model data structures. This value is never overridden.
|
Width
|
1. The signal width of this external input.
|
MemoryMapIdx
|
[-1,-1,-1]: used to populate global data map record (GlobalMemoryMap) during code generation. Refer to
matlabroot/rtw/c/tlc/mw/globalmaplib.tlc for usage information on the MemoryMapIdx field.
|
HasObject
|
0: Has a Simulink.Signal object that is used to map the external inputs to a specific location. This will be = 1 if this port is associated with a Simulink.Data object.
|
DataTypeIdx
|
0: The default signal data type is real_T.
|
ComplexSignal
|
no: The default signal is not complex.
|
DirectFeedThrough
|
yes: The default assumes the root inport requires its input.
|
SigLabel
|
"": Label on the output segment of the inport block.
|
StorageClass
|
Auto: The default value specifies that the Real-Time Workshop decides how external signals are declared.
|
CustomStorageClassVersion
|
0: Custom storage class version used
|
StorageTypeQualifier
|
"": The default type qualifier is empty.
|
}
|
|
NumExternalInputs
|
Integer number of records that follow, one per root-level inport block
|
ExternalInput {
|
One record for each external input signal (i.e., root inport).
|
BlockName
|
Input port block name with special characters removed so it can be used in comments.
|
Identifer
|
Unique name across all external inputs to be used within the external input vector/structure.
|
TID
|
Integer task id (sample time index) giving the SampleTime record for this inport block.
|
Width
|
Signal width.
|
Dimensions
|
Vector of the form [nRows, nCols] for the signal. Only written if number of dimensions is greater than 1.
|
DataTypeIdx
|
Integer index of DataType record corresponding to this block. Only written if index is not 0.
|
ComplexSignal
|
yes: Only written if this inport signal is complex.
|
SigLabel
|
Signal label entered by user.
|
DirectFeedThrough
|
no: Only written if this inport doesn't require its signal when MdlOutputs is called.
|
StorageClass
|
Only written if not Auto. This setting determines how this signal is declared.
|
StorageTypeQualifier
|
Only written if not empty.
|
HasObject
|
HasObject = 1 if this port is associated with a Simulink Data Object.
|
Object {
|
Object record is written if HasObject = 1. See "Object Information in the model.rtw File" in the Real-Time Workshop User's Guide. Also see Object Records.
|
}
|
|
}
|
|
ExternalOutputs {
|
External outputs (root outports) from the block diagram.
|
|
|
ExternalOutputDefaults {
|
|
RecordType
|
ExternalOutput. The record type is used by TLC in general processing of the model data structures. This value is never overridden.
|
Width
|
1: Signal width (default is 1).
|
MemoryMapIdx
|
[-1,-1,-1]: used to populate global data map record (GlobalMemoryMap) during code generation. Refer to
matlabroot/rtw/c/tlc/globalmaplib.tlc for usage information on the MemoryMapIdx field.
|
SigLabel
|
"": Label on the input segment of the outport block.
|
HasObject
|
0: HasObject = 1 if this port is associated with a Simulink Data Object.
|
}
|
|
NumExternalOutputs
|
Number of ExternalOutput records that follow. This is equal to the number of root level outports.
|
ExternalOutput {
|
One record per root-level outport block.
|
Block
|
[sysIdx, blockIdx] of the outport block.
|
Width
|
Signal width. Only present if not 1.
|
Sysidx
|
[externalOutputVectorIndex, SignalWidth]
|
Dimensions
|
Vector of the form [nRows, nCols] for the signal. Only written if number of dimensions is greater than 1.
|
SigLabel
|
Label on the port signal, if any.
|
}
