Hi sancruz Thanks for your reply. Well I think made all follow the intructions I delete the files with windows explorer, I follow an video posted on youtube, https://www.youtube.com/watch?v=s7GhMZZ_0GQ&ab_channel=ElectricalAutomationHands-On also see another video, they do the same but the SMC have a empty program. but a odd thing never delete de IP address... What you think? |

Hi, the reset can also be done with an 2MB SMC. In this case: SIMATIC S7 S7-1200 Programmable controller
"Do NOT delete the hidden files "__LOG__" and "crdinfo.bin" from the memory card." -> proceedure up to including step "4."
