128 KB nonvolatile program storage for compatible S7-300, C7 and ET 200 systems.
Siemens 6ES7953-8LG30-0AA0 is a SIMATIC S7 Micro Memory Card with 128 KB of 3.3 V Nflash memory. Siemens identifies this exact order number for compatible S7-300, C7 and ET 200 systems. It supports program and project storage within the documented host architecture and is now supplied as a spare-part item for installed systems. Because related Siemens cards differ in capacity, revision and supported controller families, procurement must be based on the full order number, the installed CPU or interface module, the engineering project and clear label photographs. Siemens lists 6ES7953-8LG31-0AA0 as the successor.
