If Power is Lost While the Report Function is in Progress
If a power disruption occurred while the report function was in progress, the report
function will resume after the power is restored. The exact operation will vary
depending on whether the power is restored before or after the scheduled time to
create a report.
Time of Recovery Report Operation
After the time to create the Report data are created immediately after power is restored. The
report measured/computed data up to the time of the power disruption are
used. For the next scheduled report, data after the power recovery
are used.
Before the time to create After power is restored, report data are created at the time of the
the report next normally scheduled report. All measured/computed data
excluding the power disruption period are used.
How the Measured/Computed Data Are Handled When There is an Abnormality in
the Data
Type of Abnormal Data Report Data
Average value Max/Min value Sum value
Positive over* not used used not used
Negative over* not used used not used
Error not used not used not used
Burnout: Positive (+) over range not used used not used
Burnout: Negative (–) over range not used used not used
* “over range” for measurement channels or “computation overflow” for computation channels
Displaying the Report
The reports can be displayed using the key operations. For a displayed example,
see page 1-25.
•Status Display
If the data of a measurement or a computation channel enter any of the conditions
listed below within the relevant time period (one hour for hourly reports for example), a
symbol that indicates the condition is output to the report.
Data Condition Symbol
Common to measurement and computation channels
Measurement error or computation error E
For measurement channels
Positive (+) over range

O
Negative (–) over range

Burnout: Positive (+) over range

For computation channels
Positive (+) computation overflow (when the value exceeds 3.4E + 38) O
Negative (–) computation overflow (when the value falls below –3.4E + 38) O
