Report Function

This function is used to create hourly, daily, weekly, and monthly reports. For the setting
procedure, see section 9.5.

• Report Data Types

You can select from four types among maximum value, minimum value, average

value, sum value, and instantaneous value. Report data is calculated from the
measured values that have been sampled at the scan interval.

• Report Type

Type

Description

Hourly report

Creates report data every hour on the hour for the previous one hour.

Daily report

Creates report data every day at a specified time for the previous one day.

Weekly report

Creates report data every week at a specified time at a specified day of the

week for the previous one week.

Monthly report

Creates report data every month at a specified time at a specified day for

the previous one month.

• Combinations of Reports That Can Be Created

You can select from hourly reports only, daily reports only, hourly and daily reports,

daily and weekly reports, and daily and monthly reports.

• Source Channels

You can select from measurement channels and computation channels. The report

data are not created for channels that are set to

Skip or Off.

• Unit of Sum Computation

In the sum computation, data are summed over the scan interval. However, for flow

values that have units /s, /min, /h, or /day a simple summation results in the actual
value not matching the computed result, because the scan interval and the unit of the
input values are different. In such cases, set the sum scale to match the unit of the
input value. In effect, the sum value with the same unit as that of the input value is
calculated.

For example, if the scan interval is 2 s, and the input value is 100 m

3

/min, a simple

summation would add 100 every 2 s resulting in 3000 after one minute. However, if
the sum scale is set to /min, then 2 s/60 s is multiplied every scan interval before the
value is added giving a result that has an m

3

/min unit.

The following converting equations are used to compute the sum. The unit of the scan

interval is seconds.
Off:

Σ(measured data every scan interval)

/s:

Σ(measured data every scan interval) × scan interval

/min: Σ(measured data every scan interval) × scan interval/60
/h:

Σ(measured data every scan interval) × scan interval/3600

/day: Σ(measured data every scan interval) × scan interval/86400

• Displaying the Report Data

You can display the report data using keys.
For the operating procedure, see section 4.5.

• Saving the Report Data

See section 1.4, “Data Storage Function.”

• Numeric Display and Recording

The numeric range of the report data is from –9999999 to 99999999 excluding the

decimal point (except –3.4E+38 to 3.4E+38 for sum values).

For the data handling of special cases, see “Special Data Handling” in this section.
For details on the report file format, see appendix 3.
