The cumulative counter calculates an approximation to the integral of analog
input 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 input value in the industry unit obtained after scal-
ing. For example, 100.0 count hours indicates a value equivalent to an analog
input 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 CX-Integrator in units of 0.1 hour
or minute.
Monitor values can be set in the Slave Unit. When the cumulated count value
exceeds the set monitor value, the Cumulative Counter Flag in the area for
Generic Status Flags turns ON.
