Posted 20 May 2022 Thank you very much IO_Rack. It seems that Rockwell has removed the firmware of 1756-L55 rev. 15.56 out, I could not find from the link. Can anyone share alternative ways? Share this post Link to post Share on other sites
Posted 21 May 2022 rockwell has not removed it, it is just locked and you must call tech support and prove you really need the firmware. Share this post Link to post Share on other sites
