4.3 Executing User Programs

User programs (application programs) can be executed using the following methods.
Select the most appropriate method to meet the objective.

4.3.1 Executing from the SYSTEM MENU "EXECUTE PROGRAM"

Select the program to be executed at the SYSTEM MENU "EXECUTE PROGRAM" menu.
In such a case, the selected program will always be executed from the start.
Refer to Chapter "4.5.2 Executing User Programs (EXECUTE PROGRAM Menu)" for details.
4.3.2 Automatically Executing the Program Set at the SYSTEM MENU
when Turning the Power ON
Select the program to be executed at the SYSTEM MENU "EXECUTE PROGRAM" menu, and then turn
the BHT power OFF. The selected program will executed automatically the next time the BHT power is
turned ON.
If the resume function has been set, the BHT will resume from the position in the program that was
stopped when the BHT power was last turned OFF.
Refer to Chapter "4.5.6 System Environment Settings (SET SYSTEM Menu)" for details.
4.3.3 Executing the First Registered Program by Turning the Power ON
(BHT System Directory Management Program Function)
If no program has been selected at the SYSTEM MENU "EXECUTE PROGRAM" menu and the BHT
power is turned ON, control will switch to the directory management program, and the first of the programs
(.PD4) registered in the BHT will be executed.
If the resume function has been set, the BHT will resume from the position in the program that was
stopped when the BHT power was last turned OFF.
If downloading multiple programs after system initialization, programs are registered in the system in the
order in which they are downloaded, and therefore ensure that the program to be executed is the first
program downloaded.
If a program is later downloaded for purpose of upgrading the version, use the same program name. The
order in which programs are registered in the system will not change, and therefore the same program will
be executed even after upgrading the version. (∗)
∗ The system directory management program also manages files with other extensions simultaneously. If
the top file from the first registered program is deleted and a new program is downloaded, the new
program will be registered in the position vacated by the deleted file and therefore caution is advised. It
is recommended that the program to be execute after turning on the BHT power is first downloaded
following system initialization.
