DeltaV SRX Controller w/ProVox IO for DeltaV Pulse Discrete Input

What is the range of pulse frequency of Pulse Discrete Input that can be read by a DeltaV SRX Controller where IO signal originates in ProVox IO for DeltaV?

  Not finding much information on this for you. From the DeltaV documentation, the DM6371 Pulse count input is supported, but documentation does not indicate beyond following:
  
  The valid range for the PULSE_DURATION parameter (DI cards, Discrete Output Momentary channel types) is 0.1 to 25.5 in 0.1 increments. The valid range for the RATE_PERIOD parameter, available on PCI cards is 0.1 to 5 seconds in 0.1 increments.
  
  That indicates a frequency of 10Hz max. hmm... In DeltaV, the Pulse Count function is accomplished in the IO card, which then serves up a count integer or a frequency, depending on the IO channel type. Standard DI card in DeltaV is 75 Hz, PCI channel on Multi Function card is 50 KHz, and CHARM DI's provide 10KHz.
  
  Hopefully someone can help you with the Proxox IO card.
