Table 6-14 Steps to Upload a Setpoint Schedule using Modbus Function Codes 3, 6, 16

Step
1 Set the scheduler to RESET by writing any number to Reset (p. 70). This can be done either
with function code 6 or 16.
2 Load the schedule into the setpoint scheduler block by writing the schedule number to
Current Program Number (p. 69). This is a floating point register and requires a multiple
register write (function code 16)
3 Read the header information desired. Guaranteed Soak Limits 1-8 (p. 69), Jog Segment (p.
69), Time Units (p. 70). Use function code 3.
4 Read the information for each segment in the schedule (p. 71) using function code 3.
Scheduler parameters
This table contains Values of Schedulers. Fixed addresses are for Scheduler #1; see Table 6-1 for fixed
addresses of other Schedulers.
Parameters commonly used for controlling a scheduler are marked with a single asterisk*.
Parameters commonly used to define a schedule are marked with two asterisks **.
The addresses given in Table 6-15 do not necessarily apply to schedulers in the custom map. For custom
addresses view or print a report in HC Designer.
