Report Time
To set the time to make a report, define the day of the month within a 01-28 range and
the time within a 00-23 range.
• Hourly reports:
The DA makes reports every whole hour (1:00, 2:00, . . ., 23:00, 24:00). For
cumulative summation, it resets the cumulative sum at a preset time.
• Daily reports:
The DA makes reports at preset time(s). For cumulative summation, it resets the
cumulative sum at a preset time and day.
• Monthly reports:
The DA makes reports at a preset time of a certain day of the month.
Report Channels
There are sixty report channels, from R01 to R60. You can assign either measuring
channels or Math channels to each report channel. When making a report of computed
Math data, start computing before starting a report.
Computing Types
Setting Parameter Data Item for Computing
INST Instantaneous value at the time of making report
AVE Average, maximum and minimum over the computing period
SUM Sum and cumulative sum over the computing period
Sum and Cumulative Sum
• Sum : The total sum over an hour for hourly reports, the sum over a day for daily
reports or the sum over a month for monthly reports. The DA resets this value
each time it makes any of these reports.
• Cumulative sum : The total sum up to the preset time to make a report in the case of
hourly reports or the sum up to a preset time of the day to make a
report in the case of daily reports. The DA resets this value at each
preset time or at each preset time of the day for report making. The
DA does not perform cumulative summation for monthly reports.
As an example, the following illustrates the process of summation and cumulative
summation for hourly reports. The example shows a case where the preset reporting
time is 8:00.
