The program can be uploaded to the Engineering PC having Siemens Softwares If its PLC then Step 7 will be sufficient. |

But what if Udara wants to make sure that he has the latest actual DB values backed up on the MMC? In that case "Copy RAM to ROM" is actually quite useful and moreinfo on all things related to this can be found in the FAQ below: What is the effect of the STEP 7 function "Copy RAM to ROM"? @Udara: As for your orignal question, I'm afraid I can't tell you if "Copy RAM to ROM" will work when the PLC is password protected (never tried it and don't have a CPU handy right now to test it). I'd say simply give it a try (it either works or it doesn't) and let us know what the result is. I hope this helps |

Here we are. As I said, new (MPI-) parameters on MMC will be used from CPU after insert! After insert new MMC, CPU engaged an overall reset (by it self!). So I have to stop-start again and new parameters are accepted. It makes very sense for me, otherwise how to use a MMC in a new CPU (i.e. after replacement)? I change from 187k5 to 19k2 because CPU don't accept 1M5. See attach. AttachmentMMC_Test.zip (244 Downloads) |
