High-speed Counter/Pulse Output Instructions Section 3-20
Example When CIO 0.00 turns ON in the following example, SPED(885) starts output-
ting pulses from pulse output 0 in Continuous Mode at 500 Hz. When
CIO 0.01 turns ON, pulse output is stopped by INI(880).
3-20-2 HIGH-SPEED COUNTER PV READ: PRV(881)
Purpose PRV(881) reads the following data on the built-in I/O.
• PVs: High-speed counter PV, pulse output PV, interrupt input PV in
counter mode.
• The following status information.
• Range comparison results
• Pulse output frequency of pulse output 0 to pulse output 3
• High-speed counter frequency for high-speed counter input 0.
