Time History Sequence Output (THSO) Files Overview
Note:
Playout of RPC drive files at 128 Hz requires a system rate of 1024 Hz. For controllers equipped
with MTS Series 494 hardware, playout of RPC drive files at 409.6 Hz requires a system rate of
2048 Hz or 4096 Hz. Controllers equipped with MTS Series 494 hardware do not support playout
of RPC drive files as 409.6 Hz with a system rate of 1024 Hz.
Select an RPC III or RPC Pro Road Surface file to play out.
When you have selected a file, the application:
• Verifies it is a file it can read.
Important:
If you map an RPC Pro drive file channel to a station channel that supports mode switching, and
the drive file units for that channel are “%” (indicating normalized units), the file does not play
out.
• Reads in the file.
• Reads in the headers of all time history files specified in the Road Surface file and any nested road
surface files.
• Ensures that the number of channels in each drive file is not greater than the number of channels in
the station.
• Ensures that the sampling rate is supported.
• Ensures that the sampling rate and the channel calibrations (values and units) are consistent between
all drive files.
If any of these steps fail, a message displays the problem. If no problem exists, the application attempts
to map the file’s channels to the station’s channels. Next, the application checks for conflicts.
