3020 12321 Current Program Number R/W Floating Point
Indicates the present schedule number in
use. This also allows entry of a schedule
number from the HC900 stored schedule
memory (if schedules have been stored in
the controller) and will retrieve the
schedule data for a display showing a SP
schedule segment table. Typically, when
recipes are downloaded from third party
software, this will be the number
generated by the Schedule Save Request
parameter
A write to this register loads the program
into the scheduler function block; if 0 is
written, the scheduler’s schedule is
cleared.
Writing to this register is only
permissible in reset or ready mode.
