We have both GSK983Ta-H and GSK983Ma-H, once I create a new Ladder file and upload it to the control using u-disk,
what happens to the old file? Does it stay in the control. Is there a way to remove old file? How does the control know which to use?
Once you create a new Ladder file and upload it to the control using u-disk, the current ladder file will be replaced.
And there might have some other ladder files in the backup area, no need to delete them, the system will run the one you uploaded by USB only.
