Installed between the first and second CPU module, this memory aids inter-CPU communication when more than one CPU module is present or when several CPUs access a CS7 serial interface. It supports both L-Bus and C-Bus connections, includes integrated bus termination for both buses, and offers power-failure resilience with data buffered by a back-up 3.4 V battery in the subrack. Additional hardware features include a system error-relay and a radio clock function, as described in Siemens SIMADYN D hardware specifications. The MM11 variant is identified by the order number 6DD1611-0AD0, with MM3 and MM4 variants offering the same form factor but different RAM capacities (MM3 2 x 64 KB, MM4 2 x 2 MB per bus).\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268259303658,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6dd1611-0ad0","provider":"GTG Hardware","version":"1.0","type":"link"}
