What to do if an error occurred and my Omron Monitor does not start up?

If an error occurred and the Ladder Monitor does not start up, there could be several reasons. First, the ladder program might not have been transferred; in this case, add a check to the ladder program and then download again. Second, the controller model might not match that set in the project settings; correct the controller model and then download again. Third, the SD Memory Card might not be accessible; check whether or not the SD Memory Card is mounted, ensure that the SD card allows reading and writing to be performed normally using a PC or other device, and use an SD Memory Card recommended by OMRON.
