First time on this forum or any other so, sorry if this is not the way I'm supposed to use it. We have a 2 year old machine with an S7-300. After a power supply failure and replacement very old values got loaded into all parameter fields on the HMI. However, the PLC logic remained current. Clearly, we haven't been doing the right thing in storing data/programs to the MMC. Can anyone tell me the difference between 'download user program to memory card' and 'save to memory card'. See attached. Many thanks in advance for any advice you can offer. ------------------------------------------------------------------------------------------ |

Copy RAM to ROM, will save actual values to initial values. |
