Procedure for Uploading Setpoint Schedules
Table 6-19 Steps to Upload a Setpoint Schedule using Modbus Function Codes 3, 6, 16
Step Action
1
Set the scheduler to RESET by writing any number to 12367 (304E). 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
registers 12321 and 12322 (3020 and 3021). This is a floating point register and requires a
multiple register write (function code 16)
3
Read the header information desired -- registers 12331 (302A) - 12347 (303A) and register
12368 (304F) using function code 3.
4
Read the information for each segment desired using function code 3 -- registers 3200 -
322F for segment 1, 3230 - 325F for segment 2, etc.
