Hello Nemanja; What kind of memory card do you have in the CPU 315-2PN/DP? The MMC is essential as a repository of the Load Memory fpr the CPU, since that is where the programs are downloaded to. If you are missing the MMC and try to download, you will get a message like you have, error code 294:38. See this discussion on a similar error code:
How can you obtain an overview of the memory concept of SIMATIC S7-300 CPUs and C7 devices? https://support.industry.siemens.com/cs/ww/en/view/7302326 In your case look at the description of point 4, SIMATIC S7-300 CPUs and C7 Devices With MMC Bay, List of available MMC for S7-300 (FEPROM cards) 256 Kbyte FEPROM 6ES7 951-1KH00-0AA0 1 Mbyte FEPROM 6ES7 951-1KK00-0AA0 2 Mbyte FEPROM 6ES7 951-1KL00-0AA0 4 Mbyte FEPROM 6ES7 951-1KM00-0AA0 Hope this helps, Daniel Chartier |
