SL-5-5 OSI Trace File Player

This FMU is able to play OSI trace files. It supports the formats .mcap, .osi, and .txth. For .osi and .txth files, the file names have to comply to the OSI trace file naming convention, as the player parses the name to identify the message type (e.g. SensorView). The folder containing the trace files has to be passed as FMI parameter trace_path. The trace file player is build according to the ASAM Open simulation Interface (OSI) and the OSI Sensor Model Packaging (OSMP) examples.

An exemplary trace file is available in folder trace_file_examples.

Parameterization

The following FMI parameters can be set. At least the trace_path has to be set. Otherwise, the FMU will return with an error.

Type	Parameter	Default	Description
String	trace_path	""	Path to the directory containing one or more OSI trace files
String	trace_name	""	Filename of the trace file to be played. If empty, the first OSI trace file in the given directory is played.
