Schedule Objects
Each schedule object has a block of registers that are
used to maintain the schedule.
The first object starts at register address 20001 and the
second object starts at 20291. Table60 indicates the list
of schedule objects and their associated registers.Each
day has eight pairs of ON/OFF times. Day 1 represents
Monday, Day 7 represents Sunday, and Day 8 & 9
represents Calendar day(s). If a day has fewer than
eight pairs, all empty pairs are filled with 0xFFFF on its
ON/OFF time. Schedule properties can be edited with
function code 06 and 16 and read with function code 3.
Due to constraints in the code, you can only remove an
entry by writing 0xFFFF with function code 06.

Table 60. Schedule Registers
Note that the first entry of each day’s time slot has to be 00:00 to indicate midnight and the time slot’s value can be
changed but not its time. To schedule 24 hours ON, only one entry is needed; set the midnight value to 0x0001 and it
will be turned OFF at midnight the next day. To delete an entry, fill the time and value with 0xFFFF. Only one entry can
be deleted at a time. You cannot delete all entries with one write.
Configuration properties are in sets for each Schedule and have the address space shown in Table 61. Each object has
290 registers and there are 16 objects per panel.
