PLCGurus.NET - How To Downgrade ControlLogix Processor Firmware 

Taught me at Niagara College and still teaching me in my Controls Career. Much appreciated Fred!

Thank you for sharing the video! Let's not forget to make a backup of your program before you upgrade or downgrade the firmware because this process will erase all the date and program within the processor. Thank you again,

Great Tutorial Demo and all the ways you can access Control Flash for the firmware upgrade or downgrade. Its a very good thing to know how to do. The Control Flash Plus is the new Firmware Flash utility and much faster with quite a few enhances. From the recent RA TechED 2019 I attended in Orlando, FL i sat in a session on the new Control Flash Plus for firmware installation and its been revamped/upgraded and even cooler than before bit and much faster also. RA Reps there also demonstrated that they wanted to add some cool new functionality and i'm sure i'm forgetting stuff already, but you can if connected to a Network the utility can find what has what firmware installed currently. It can then Firmware Flash multiple devices all at once now and I believe up to 10 devices max all at the same time showing you in real time a time bar on each device being flashed. Both are very cool features added. I think i wrote down more stuff for notes, but that's what i currently remember without consulting my notes.

Hi ,Thanks for the videos ,You are doing very use full ,very clear and excellent tutorials .Please can you do some video for process control concepts and batch process ,machine control technique with real example.

Thanks a lot. No affence but I have a question, does it necessary to backup the previous programs before the update? Means during the updating or downgrade of the firmware there wil not be the risk to lose the program in the L61 controller?

good video but, is the same procedure for studio 5000 software??

Are you doing face to face private sessions ?
