Hello akshay s; Looking around the web, I found this image (from an automation reseller) of a 6ES7952-1AK00-0AA0 1MB RAM MC for a S7-400 CPU. Examine the connector design for the MC, it corresponds to the 4MB MC format you show in your first image. This also corresponds to the design I remember from my S7-400 programming days. The connector for the 2MB RAM MC in your first picture does not look like a Siemens MC design. Can you remember if that was purchased directly from Siemens? It has been rumored that cheap knock-offs from unrecognzed providers (EBay, Alibaba for example) sometimes do not quite match the original requirements from Siemens... If you intend to look up more details on he RAM and FEPROM MCs used with S7-400 CPUs, have a look at ths FAQ: https://support.industry.siemens.com/cs/ca/en/view/73159687 Hope this helps, |
