7.12.8 Pulse Accumulator Buffer Example
This user block example connects to YUAA pulse accumulator inputs to provide a Total Counts output that is a 32-bit integer. It handles 16-bit rollovers and implements a
user reset of total counts to zero. The 16-bit accumulator resets to zero when the I/O pack reboots or the channel’s mode is changed. The counter increments when the
input voltage transitions above the PAThreshold setting. The next pulse after accumulator is at 65535 will result in the accumulator rolling over to zero and continuing to
count from there on following pulses.
