Property Summary

Name	Description
IsBus	True if this port is connected to a bus.
IsSampleHit	True if this port produces output or accepts input at the current simulation time step.
SampleTime	Sample time of this port.
SampleTimeIndex	Sample time index of this port.
SamplingMode	Sampling mode of the port.

Properties

IsBus

Description

True if this port is connected to a bus.

Data Type

Boolean

Access

RO

IsSampleHit

Description

True if this port produces output or accepts input at the current simulation time step.

Data Type

Boolean

Access

RO

SampleTime

Description

Sample time of this port.

Data Type

[period offset] where period and offset are values of type double. See How to Specify the Sample Time for more information.

Access

RW for MATLAB S functions, RO for other blocks

SampleTimeIndex

Description

Sample time index of this port.

Data Type

integer

Access

RO

SamplingMode

Description

Sampling mode of the port. Valid values are:

Value	Description
'frame'	Port accepts or outputs frame-based signals. The use of frame-based signals requires a DSP System Toolbox license.
'inherited'	Sampling mode is inherited from the port to which this port is connected.
'sample'	Port accepts or outputs sampled data.

Data Type

string

Access

RW for MATLAB S functions, RO for other blocks
