Note
• When the channel data is in the condition shown in the table below, the
Er
,
Ov
, or
Bo
status
is output to a report.
Data Condition Status
Error
Er
Measurement and external input channels
Positive over range
Ov
Negative over range
Ov
Burn out detection
Bo
Computation channels
Positive computation overflow (when the value exceeds 1.79E + 308)
Ov
Negative computation overflow (when the value falls below –1.79E + 308)
Ov
• The report output value of
Ave
,

varies depending on the channel
data condition as shown in the table below.
Item Data Condition of Measurement/ Report
External Input Channels Output Value
Ave
When all of the data are errors or over range (Space)
Max
, • When all of the data are errors (Space)
Min
, • For +over range (includes burnout detection) 99999
Inst
• For –over range (includes burnout detection) –99999
Sum
• When all of the data are errors or over range (Space)
• When the sum value exceeds approx. 3.4E + 38 9.99
• When the sum value is below approx. –3.4E + 38 –9.99
Item Data Condition of Computation Channels Report
Output Value
Ave
When all of the data are errors or computation overflow (Space)
Max
, • When all of the data are errors (Space)
Min
, • When the maximum value or instantaneous value
exceeds 99999999 999999999
Inst
• When the minimum value or instantaneous value is less
than –9999999 –999999999
Sum
• When all of the data are errors or computation overflow (Space)
• When the sum value exceeds approx. 3.4E + 38 9.99
• When the sum value is below approx. –3.4E + 38 –9.99
* The decimal place that was specified when the span for the channel was specified
applies to the maximum and minimum values or the instantaneous values. For example,
if the span setting of the channel is “200.0,” then “999999999” is output when the value
exceeds “9999999.9” and “–999999999” is output when the value is below “–999999.9.”
