Hello semooo all LED's flashing typciallyindicates a faulty CPU. In you case though the cause for this appears to be related to the download of yoru (perhaps wrongor corrupted) program. Questions/Suggestions: 1.) Do you have a new (or empty) MMC that you can slot into the CPU andsee if it fixes the flashing LED problem 2.) If not, have a lookat the links below on hwo to reset and/or format the CPU and/or MCC How do you reset a SIMATIC S7-300 CPU and MMC (default reset or overall reset)? Which devices can you use to read from, write to or delete from an S7-300 MMC (Micro Memory Card) outside the CPU? Ihope this helps |

Hello semooo You'll get he message "Do you want to replace the online system data with the offline one" any time you try to download the system data Block (SDB) to the PLC (the SDB contians the compiled HWconfig and Netpro configuration data) and downloading the SDB is generally a permissble procedure. Without knowing what exactly you did, how up to date and/or correct your SDB data was, what was in the PLC before etc. etc.,I could only speculate about the root cause of your problem. Having said that, if you are dealing with a safety program/PLC you would of course follow the appropiate download procedure for the safety relevant program as per SIMATIC Industrial Software S7 Distributed Safety - configuring and programming manual, wouldn't you? |
