Yokogawa Button Operated MV2000 - Manual (Page 297)

App-14 M-4660
Note
• When channel data is in a condition shown in the table below, the MV outputs Er, Ov, or Bo
to the report.
Data Condition Status
Error Er
Measurement and external input channels
Positive range-out Ov
Negative range-out Ov
Burnout detection Bo
Computation channels
Positive computation range-out (when the value exceeds
approx. 3.4E+38) Ov
Negative computation range-out (when the value is less
than approx. –3.4E+38) Ov
• The report output value of Ave, Max, Min, Sum, and Inst varies depending on the channel
data condition as shown in the table below.
Item Data Condition of Measurement or External Input
Channels Report Output
Value
Ave When all of the data are errors or range-outs (Space)
Max, • When all of the data are errors (Space)
Min, • Positive range-out values (includes burnout detection) 99999
Inst • Negative range-out values (includes burnout detection) –99999
Sum • When all of the data are errors or range-outs (Space)
• When the sum value exceeds approx. 3.4E+38 9.999999E+99
• When the sum value is less than approx. –3.4E + 38 –9.999999E+99
Item Data Condition of Computation Channels Report Output
Value
Ave When all of the data are errors or computation range-out (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 range-outs (Space)
• When the sum value exceeds approx. 3.4E+38 9.999999E+99
• When the sum value is less than approx. –3.4E + 38 –9.999999E+99
* The decimal place for maximum, minimum, and instantaneous values is set to the
decimal place that was specified for the span setting of the expression. For example, if
the span setting of the expression is 200.0, the MV outputs 999999999 when the value
exceeds 9999999.9 and –999999999 when the value is less than –999999.9.
