Hello all, First post! Desperate! I'm working with a 414H system. Both CPU's have 2MB Flash cards installed. System was up and working good. I attempted to backup the program to the flash cards, but instead of selecting "Download user program to memory card", I selected "Save to memory card". I think this was my first mistake. I only did this on CPU 2, and attempted a reboot of both CPU's. CPU 2 will not go into run now, even after performing a "Download user program to memory card". Attempted to re-download the user program and HW Config several times with no luck. Not sure what to try next. Maybe remove the batteries and flash cards after powering down and start from scratch with a fresh download? I would like to format the CPU 2 flash card, but I don't have a PG with a PCMCIA port available. Thanks ahead for the help, Attached is the latest diag file.

Hello Zackbo , The easiest way is to use SIAMTIC Field PG to delete the content of External Flash memory card via STEP 7.The content can not be accessed via ordinary card readers.If your machine tolerate, both CPUs unavailable for a moment remove both Flash and test your CPUs with only hardware configuration.If there is no error, switch to test B. In test B , find the final off-line project and download it to Flash memories of both CPUs and Start both CPUs with overall memory reset.In this manner, content of both Flashes are deleted and your valid identical data is stored in both. I hope this helps, hdhosseini |

Hi, hdhosseini, What does this mean and how is it performed: 'overall memory reset'. Thanks! |
