Set point scheduler
A suite of Setpoint Scheduler blocks provides extensive control of multiple process setpoints using a
common time base. A single schedule may be up to 50 segments in length and includes auxiliary block
data. Up to 10 schedules may be stored in the controller’s memory.
An operator can interact with the configured Setpoint Schedules through the Setpoint Program Operate
display at the operator interface.
Eight character labels and four character engineering units are provided for each process variable of the
master and auxiliary setpoint blocks. Labels and on/off descriptions are also provided for the Digital Event
block. Assigning these labels first [see Setpoint Scheduler Display Configuration (page 119)] will aid
you in the schedule configuration process. These labels will appear in the configuration dialog boxes.
Setpoint Schedule Setup or Edit consists of configuring each segment of the schedule and assigning values
for all eight Setpoints of the segment and the Guaranteed Hold Type for each.
You can also set up to 16 events for each segment. Time Units, Recycle Segment, and Recycle Counts
selections are included on this dialog box.
You can also assign values to all eight Auxiliary Outputs for each segment by clicking the “Edit Aux”
button on the dialog box.
