Before trying to download a program, you must be sure that your controller is in the correct mode for that operation. The three modes are as follows:
RUN Mode: Can only be changed from the controller and can’t be stopped by any other means.
REMOTE Mode: Controller can be switched from RUN or PROGRAM mode through a host computer.
PROGRAM Mode: Can only be changed from the controller. The program won’t run until it is switched to RUN mode, but programs can be downloaded any time.
