Saving and Compiling a Program
This chapter discusses the procedures used to save and compile ladder
programs. Topics include:
•
save and continue editing
•
save and exit offline editing
•
view memory layout
When you are entering a new program or editing an existing program, the
ladder program is stored in the work area of the HHT. After completing your
editing session, you must save your program to the HHT RAM memory.
First, your program is compiled, transforming it into a more efficient
package. Then the program and data files are updated. When you save and
exit, a summary of the data words and instruction words used along with the
available memory is updated.
Since programs are created or edited offline, it is important to save your
work before downloading it to the processor.
As mentioned in the previous chapter, whenever you are creating a new
program or editing an existing one, you should periodically save your work.
In the event of a power loss to the HHT, any edits that you have made up to
that point, are not recoverable. Save and Continue (SAVE_CT) allows you
to save your work and continue editing. Save and Exit (SAVE_EX) allows
you to save your work and exit offline editing.
To save your program, start at the main editing display:
