Enter the name of the file you want to download, then click on “Open.”
Downloading of the sequence program begins.
Once downloading is complete, the “Completed” message appears.
Note
Do not use the keyboard while the sequence program is being downloaded.
Doing so may result in a download error.
The numbers of the sequence program and line in which the first downloading error was detected will be
displayed. (The figure below shows an example in which the first error was detected in Line 5 of
sequence program 1.)
The command and parameters of the error line will be cancelled, and subsequent lines will be correctly
received by the controller. Since no command exists in the cancelled line, the error sequence program, if
executed, will be halted at the cancelled line. Correct any error sequence program and repeat the
download.
Note
You cannot overwrite an existing sequence program. To replace the existing
sequence program with a new one, first delete the applicable sequence program
saved in the controller and assign the same sequence program number to the new
sequence program before downloading it to the controller.
Memo
•
You can download several sequence programs at once by writing and saving them in a
single text file.
•
If the same sequence program number is assigned for more than one sequence
program within a single text file, the first sequence program downloaded will be enabled
with the remaining sequence programs cancelled.
