Report Channels
There are sixty report channels, from R01 to R60. You can assign channels for measuring objects
being computed or computation channels and the type of computing on a report-channel basis.
When making a report of computed data, let computing start before letting the report making start.
Types of Computing
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 the case where the preset time to make a report is 8:00.

Unit of Summation (SUM UNIT)
Such input data items as the flowrate that have a unit in /sec, /min, /hour or /day, when simply
summed, give results of computing different from their actual values. This occurs because the unit
of such a data item differs from that of the measurement interval. In that case, you can take the
output after having converted the unit of summation so it matches that of the input data item applied.
