Changing files
RPC III or RPC Pro drive files (drv or tim) are used to play out to the station.
When you have selected a file, the application performs a series of activities. If any of these steps fail, a
message displays the problem. If no problem exists, the application attempts to map the file channels to
the station channels. Next, the application checks for channel conflicts.
You may make limited changes to the contents of an RPC time history file between the time the name is
entered here and when it is actually used during the execution of a procedure. MPE compares the file
header at execution time to its contents during the definition phase. If it detects any differences in any of
the following parameters, an error status is returned and the test is terminated:
• RPC File Type
• Number of channels
• Points per group
• Sampling rate
• Channel full scales
• Channel descriptors
• Channel units
• Channel mapping

Time History Controller Rates
Time History rates supported by the controller are dependent on the system rate specified in your controller
hardware interface file:
Time History Controller Rates
File Rate (Hz) System Rate (Hz)
1024, 512, 409.6, 256, 204.8, 128, 102.4 1024
2048, 1024, 512, 409.6, 256, 204.8, 128, 102.4 2048
2048, 1024, 512, 409.6, 204.8 4096
Note:
Playing out the 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 requires a system rate of 2048
Hz or 4095 Hz. Controllers equipped with MTS Series 494 hardware do not support playout of RPC
drive files at 409.6 Hz with a system rate of 1024 Hz. When using this sampling rate with a 1024
