Axis Scheduling Chapter 7
7. To assign the axes to the Alternate Update Periods, use the positioning
arrows.
The axes appear in the Alternate columns.
8. Choose the Alternate 1 Update Period.
The multipliers range from 2…32, so if the base update rate is 2.0, the
values in the alternate rates are 4, 6, 8, 10, 12…32. If the base update rate
is 3.0, the values are 6, 9, 12, 15, and so on.
If you change the Base rate to a value that the Alternate rate value is not a
multiple of, a warning flag appears next to the Alternate rate.
