4. Enter the name of the file you want to download, then click on "Open."
Downloading of the 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 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 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
program, if executed, will be halted at the cancelled line. Correct any error program and repeat
the download.
Note
You cannot overwrite an existing program. To replace the existing program with a new one, first
delete the applicable program saved in the controller and assign the same program number to the
new program before downloading it to the controller.
You can download several sequence programs at once by writing and saving them in a single text file.
If the same program number is assigned for more than one program within a single text file, the first program
downloaded will be enabled with the remaining programs cancelled.
