Processing Reports with Abnormal Input Values or Overflow Values
You can select how reports are processed when an error occurs on the channel
(measurement or MATH channel) for which a report is created.
For report processing during abnormalities, see “Report Operation Settings 1” in section 3.12.
Special Processing of Report Results
• Status of channel for which the report is created
The following demonstrates cases in which an abnormal input value or overflow value
occurs on the channel for which the report is created.
Channel Type
Status
Description
Measurement channel
Abnormal input
value
The module of the target channel is
disconnected, or some other abnormality
Overflow value
Input value exceeds the measurement range
Computation channel
Overflow value
When the computed result on a MATH channel
exceeds the MATH span setting range
*1
• Processing during abnormal input
*2
Report Data Type
Notation
Process Description
Maximum/minimum/
integral/average value
Error
The report data is an error
Skip
Uses the previous value of the channel on
which the abnormal input value occurred
• Processing during an overflow
*3
Report Data Type
Notation
Process Description
Integral/average value
Error
The report data is an error
Skip
Uses the previous value on the channel on
which the overflow value occurred
Limit
*4
The overflow value is replaced with the upper
or lower limit
*1 For the MATH span setting range, see “MATH Span” in section 1.15.
*2 The instantaneous value during abnormal input is 99999999 (decimal place depends on the
setting)
*3 The maximum, minimum, and instantaneous values during an overflow are handled as
follows.
• +Over: Measurement channel 99999 (decimal place depends on the setting)
MATH channel
99999999 (decimal place depends on the setting)
• –Over: Measurement channel –99999 (decimal place depends on the setting)
MATH channel
–9999999 (decimal place depends on the setting)
*4 The lower/upper limit value replaced differs depending on the channel’s setting condition.
Measurement channel: Measurement range upper and lower limit
Scaled measurement channel: Upper and lower limit of scaling
Computation channel: Span upper limit and lower limit
