Road Surface File Note Playout of RPC drive files at 128 Hz requires a system rate of 1024 Hz.
Note 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.
Selects an RPC III or RPC Pro Road Surface file to play out.
When you have selected a file, the application:
• Verifies that it is a file it can read.
Important If you map an RPC Pro drive file (.seq) channel to a station
channel that supports mode switching, and the drive file units for
that channel are "%" (indicating normalized units), the file will 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 will display the problem. If no problem
exists, the application will attempt to map the file’s channels to the station’s
channels. Next, the application checks for conflicts.
Passes Selects the number of passes the Road Surface file will play out each time the
process runs, as specified on the General tab.
