Simulink.SimulationData.Signal

Container for signal logging information

Description

Simulink^® uses Simulink.SimulationData.Signal objects to store signal logging information during simulation. The objects contain information about the source block for the signal, including the port type and index.

Property Summary

Name	Description
BlockPath	Block path for the source block for the signal
Name	Name of signal element to use for name-based access
PropagatedName	Propagated signal name, if any
PortIndex	Numeric index of port that was logged
PortType	Type of port that was logged: for signal logging, the port type is 'outport'
Values	Time and data that were logged

Properties

BlockPath

Description

Block path for the source block for the signal

Data Type

Simulink.SimulationData.BlockPath

Access

RW

Name

Description

Name of signal element to use for name-based access

Data Type

character vector

Access

RW

PropagatedName

Description

Propagated name of signal element

Signal logging and root Outport block logging data for a signal captures the propagated signal name if the logging format is Dataset and:

• For signal logging, you:

  • Mark the signal for signal logging and in the Signal Properties dialog box select Show Propagated Signals.

  • Enable Configuration Parameters > Data Import/Export > Signal logging.

• For root Outport block logging, you select Configuration Parameters > Data Import/Export > Output.

The propagated signal name does not include angle brackets (<>).
