11.1 Resume Function
The resume function automatically preserves the current status of a running application pro-
gram (user program) when the BHT is turned off, and then resumes it when the BHT is turned
on. That is, even if you unintentionally turn off the BHT or the automatic powering-off function
turns off the BHT, turning on the BHT once again resumes the previous status of the program
to allow you to continue the program execution.
The resume function is effective also during data transmission in execution of an application
program, but a few bytes of data being transmitted may not be assured.
The resume function does not work after execution of System Mode or any of the following
statements:
• END
• POWER OFF
• POWER 0
NOTE
Even if you become disoriented with the operation during execution of an application
program and turn off the BHT when the resume function is enabled, the BHT cannot
escape you from the current status of the program. This is because the resume func-
tion will not initialize the variables or restart the BHT. (You can disable the resume
function in System Mode.)
NOTE
In preparation for maintenance or inspection jobs involving execution of System
Mode (which will disable the resume function), store important information con-
tained in user programs by using files or register variables, preventing your current
operation jobs from getting crippled.
