Setpoint Programmer Additional Parameters:
1F00 7937 Current Program Number* R/W Floating Point
Indicates the present profile number in use.
This also allows entry of a profile number
from the HC900 stored profile memory (if
profiles have been stored in the controller)
and will retrieve the profile data for a display
showing a SP profile segment table.
Typically, when recipes are downloaded from
third party software, this will be the number
generated by the Program Save Request
parameter
A write to this register loads the program into
the set point programmer function block; if 0
is written, the function block’s program is
cleared.
1F02 7939 Program Save Request** R/W Floating Point
Assigns profile parameters downloaded to a
profile number such as 1. This is required by
the HC900 to be the last parameter
downloaded. This overwrites what is in this
HC900 SP Profile memory location on each
download of a new SP profile.

to this register is prohibited in the run mode.
