Analog I/O Slave Unit (output) Functions
Section 11-5
11-5-3 Cumulated Count
Description
The cumulated count 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
two-word area (four bytes) 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 hours
or minutes.
Monitor values can be set in the Slave Unit. When the cumulated count value
exceeds the set monitor value, the Cumulated Counter Flag in the area for
Generic Status Flags turns ON.
Note The following table shows the divisions for the cumulated counter.
