There are four types of ScheduleSelector components available in the Schedule palette, representing each of the four data types:

ScheduleSelectors may only provide links between schedules and control components that are of the same data type. For example, a BooleanScheduleSelector component only links a BooleanSchedule component to a control component of the Boolean data type. An EnumScheduleSelector links between an EnumSchedule component and a control component of the Enum data type. The same relationship applies to Numeric and String schedule selectors.

If you have schedules of different data types in the same container, the ScheduleSelector only displays the valid schedule components in the "Schedule" property options list.
