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.
