DAPL Statistical Commands

DAPL processing commands can compute on-the-fly statistics. Sometimes the statistics are the goal of the data acquisition, and sometimes they are supplementary information to monitor your processes.

HIGH

Identify the highest value in data blocks.

LOW

Identify the lowest value in data blocks.

FINDMAX

Determine the location of the highest value in a data block.

AVERAGE

Compute the average values for data blocks.

BAVERAGE

Perform averaging on multiplexed data channels, independently, in parallel.

VARIANCE, STDDEV

Compute spread statistics for data blocks.

HIGH, LOW

Compute extreme value statistics for data blocks.

PCOUNT

Count the number of samples passed through a pipe.

PVALUE

Post the latest sample value from a pipe.

RMS

Calculate RMS averages for data blocks.

Some special commands collect statistics about digital input data.

PULSECOUNT

Counts pulse edges detected on a digital port line.

CTCOUNT

Accumulates counter totals at fixed update intervals.

CTRATE

Reports new counts for a counter updated at fixed intervals.
