11-5-13 Cumulative Counter
The cumulative counter integrates the temperature input value over time to
determine the amount of heat endured by a sensor or device. The cumulative
value can be calculated in hours (
°
C
×
hours or
°
F
×
hours) or minutes (
°
C
×
minutes or
°
F
×
minutes).
For example, when the units are set to hours, a cumulative value of 100 hours
indicates a temperature value equivalent to 100
°
C continuing for one hour.
The value stored in the four-byte area (two words) is the integral value for 300
time divisions. The data is displayed according to the set conditions. (See
notes 1 and 2.)
Monitor values can also be set in the Unit. When the cumulated count value
exceeds the set monitor value, the Cumulative Counter Exceeded Flag in the
area for Generic Status Flags turns ON.
Note 1. When
°
F units are selected, the integration is performed on the
°
F values.
2. Even if the 1/100 display mode is selected, the integration is performed on
the original (
×
100) temperature values.
3. The meaning of the integral value depends on the decimal point position
for the temperature input value.
