PIAdvCalcExpDat()

Expression

String

One or more performance equations that the function computes a value for. See Expressions.

To specify multiple expressions, enter a range of cells that contain complete expressions. The function returns values for each.

STime

String

The start of the time period for which the function calculates values. See Time inputs.

ETime

String

The end of the time period for which the function calculates values. See Time inputs.

Interval

String

The interval between returned values. Enter a value and time unit that specifies the length of the interval. For example, enter 15m (15 minutes) to return a value for every 15-minute interval during the time period. See Learn about time-interval specifications.

Mode

String

The type of calculation that the function performs:

• total

• minimum

• maximum

• stdev

• range

• count

• average (time-weighted)

• average (event-weighted)

CalcBasis

String

The calculation method:

• time-weighted

• event-weighted

SampMode

String

The sampling method the function uses to determine when to evaluate Expression:

• compressed

• interpolated

SampFreq

String

The frequency that the function evaluates Expression if SampMode is set to interpolated. Enter a value and time unit. For example, set to 10m (10 minutes) to return an interpolated value for every 10-minute interval. See Learn about time-interval specifications.

MinPctGood

Number

The minimum percentage of good data required during the time period to calculate and return a value.

CFactor

Number

A factor that the function applies to the returned value. Enter 1 if a conversion factor is not needed. For time-weighted total calculations, specify a factor that converts recorded rate values to the server default time unit (units per day).

OutCode

Integer

An output code that determines what appended data the function returns and how the function orients output. See Output codes for information on how to compute the code.

This function supports bits 2, 3, 7, 8, and 9 (if Mode is set to minimum, maximum, or range).

RootPath

String

The path to the data item referenced by the expression. See Data items.
