Go online to the PLC with Step7. When you have the online view of Block folder, delete the FB's, FC's and DB's. |

Hi, please also have a look to the following FAQ: What is the effect of the STEP 7 function "Copy RAM to ROM"?There is a chapter "Delete EPROM" and a Step by Step manual to delete Blocks. Regards, Towome |
