10. Output the value from the Master Unit that is equivalent to the Output Unit's
maximum (100%) value. Adjustment is best performed using the 100% val-
ue, but can be performed using a lower value.
11. Adjust the analog value that is output from the terminal using the High Limit
slide bar, as shown in the following window. Repeat adjustments until the
correct 100% value is output from the output device. After compensation is
completed, click the Fix upper adjusting Value Button.
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.
