Data Condition
Common to measurement and computation channels
Measurement error or computation error
For measurement channels
Plus (+) over range
Minus (–) over range
Over range occurs when the input type is voltage and the input exceeds ±5% of the
measurable range.
For example, consider the case when the measurement range is 2 V and the measurable
range is from –2.000 to 2.000 V. If the input signal exceeds 2.200 V, + over range occurs.
If the input signal falls below –2.200 V, – over range occurs.
Over range occurs when the input type is TC (thermocouple) or RTD (resistance
temperature detector) and the input exceeds approximately ±10°C of the measurable
range. For example, consider the case when the measurement range is R and the
measurable range is from 0.0 to 1760.0°C. If the input signal exceeds approximately
1770.0°C, + over-range occurs. If the input signal falls below approximately –10.0°C, –
over range occurs.
For computation channels
+ computation overflow (when the value exceeds 3.4E + 38)
– computation overflow (when the value falls below –3.4E + 38)
Numerical display
The range of displayed values of report data is from –9999999 to 99999999 excluding
the decimal point. The decimal point position corresponds to the position of the decimal
point of the upper and lower limit span of the computation channel.
However, special displays are used for cases given in the table below.
• Measurement channel
Item Data Condition of Measurement Channels
AVE When all data are measurement errors or over range
(Average value)
MAX, MIN • When all data are measurement errors
(Maximum value, • + over range
minimum value) • – over range
SUM • When all data are measurement errors or over
(Sum value) range
• When the sum value exceeds 3.4E + 38
• When the sum value is below –3.4E + 38
• Computation channel
Item Data Condition of Computation Channels
AVE When all data are computation errors or over range
(Average value)
MAX, MIN • When all data are computation errors
(Maximum value, • When the maximum value exceeds 99999999
minimum value) • When the minimum value is below –9999999
The decimal position that was specified when the span for the equation was specified is reflected
in the maximum and minimum values. For example, if the span setting of the equation is
"200.0," then "99999999" is output when the value exceeds "99999999.9" and
"–99999999" is output when the value is below "–999999.9."
SUM • When all data are computation errors or
(Sum value) computation overflow
• When the sum value exceeds 3.4E + 38
• When the sum value is below –3.4E + 38
Report data are stored to the internal memory at the end of each time interval.
The maximum number of report data files (data set for each interval) that can be stored
in the internal memory is 40. For detail, see chapter 8.
