The Siemens 6ES7952-1KS00-0AA0 is a SIMATIC memory card for the S7-400 CPU family, built as a long-design 5V Flash-EPROM card with 16 Mbyte capacity. It plugs into the S7-400 CPU's memory card slot to hold the user program, block data and configuration. At 55 g, it is a field-swappable card for loading a program onto a new CPU or moving it between stations.
This is the smallest-capacity card in the long-design S7-400 line-up. If the user program, DBs and retentive data of the target CPU approach 16 Mbyte, move up to the 32 Mbyte or 64 Mbyte version of this same card family rather than risk running out of load memory after future program changes.
