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

Description:   True if this port is connected to a bus.

Data Type:   boolean

Access:   RO

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

Data Type:   boolean

Access:   RO

Description:   Sample time of this port.

Data Type:   [period offset] where period and offset are values of type double. See Specifying Sample Time for more information.

Access:   RW for M-file S functions, RO for other blocks

Description:   Sample time index of this port.

Data Type:   integer

Access:   RO

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 Signal Processing Blockset 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 M-file S functions, RO for other blocks
