Brad Donovan1 Posted May 31, 2015 Report Share Posted May 31, 2015 Hi all, I have an M91 with the text on the screen being upside down. Had one a few years ago with the same problem and though it was an easy fix back then, but can't find anything in the help files.

R.Mozes Posted May 31, 2015 Report Share Posted May 31, 2015 Hello, Attached is a program for rotating the display back to normal. Connect the PLC to the PC, choose the com port and the direction and click on flip display. Please let us know if it solved the problem.

Brad Donovan1 Posted May 31, 2015 Author Report Share Posted May 31, 2015 Thank you for this, but it didn't work. I check comm ports and it is the correct one, 232 port 1. Brad Quote Link to comment Share on other sites More sharing options...

dano3829 Posted December 30, 2019 Report Share Posted December 30, 2019 Hi, This executable worked for me. I don't know how or why the Display got flipped in field. Thanks for putting this online in 2015. ***Part of post, not related to display rotation correction, being deleted*** Quote Link to comment Share on other sites More sharing options...
