Hi I have 313-5BE01-0ABO PLC. I have to add some FB's and DB's in the existing program. After the modifications, I tried to download but i was not able to download because of memory full. So i changed the MMC with 512kb. Now i tried to download but CPU is not detecting for download. I am using Siemens PG and MPI cable for downloading. But if i put back the old MMC plc is detecting. Pls help me to sort out this.. Thanks Maruthu

hi, what is on the "new" MMC? any other "old" data on it? I guess there are data from an other project on it and the CPU is loading these properties and has an other address. Try to reset the MMc before it its used in the CPU. Have a look to these FAQ: How do you reset a SIMATIC S7-300 CPU and MMC (default reset or overall reset)? hope this helps, regards, |
