Hi : Thank you for quick reply! I saw a file called SystemImage X3 1.20.4 in the link you send to me. I want to update the runtime, OS to the latest version, which file should I download and put into micro SD or USB memory? And other question is from ctrlX CORE manual, it seems like a image update tool <rexroth-arch01-imageupdate.zip> is necessary, where can I get it? Best Regards Chen
