Note If the High Limit adjustment is not performed for the 100% value, a discrep-
ancy will occur when the Low Limit is adjusted, so always adjust the Low Limit
of Output Units before adjusting the High Limit.
The cumulative counter calculates an approximation to the integral of analog
output values over time. The cumulated value can be calculated in "count
hours" (by selecting "hours") or "count minutes" (by selecting "minutes"). The
count value is the analog output value in the industry unit obtained after scal-
ing. For example, 100.0 count hours indicates a value equivalent to an analog
output value of 100 counts continuing for one hour. The counter range for a
four-byte area (two words) for count hours or count minutes is –214,748,364.8
to 214,748,364.7. Data is displayed on the Configurator in units of 0.1 hours
or minutes.
Monitor values can also be set in the Unit. When the cumulated count value
exceeds the set monitor value, the Cumulative Counter Flag in the area for
Generic Status Flags turns ON.
