High-Speed Inputs

High-speed inputs 20 and 21 can be used as general purpose inputs or as the trigger signal for high speed data collection. Refer to the DriveDataCaptureConfigureTrigger() function topic in Automation1 Help for more information.

You can use the external PSO synchronization functions to synchronize waveform generation with an external synchronization signal. When you activate this feature, the PSO Waveform module will not generate the configured waveform when an output event is received until the rising edge of the synchronization signal occurs. Refer to the PSO Waveform Functions in Automation1 Help.
