The NCU model 572.3 ships with 64 MB of memory, CNC user memory of 0.5 MB, and PLC memory of 96 KB, described as without system software memory, and it is prepared for PROFIBUS-DP communications according to IEC 61508, enabling integration with Siemens drives and fieldbus networks. In SINUMERIK 840D\/DE configurations, this NCU functions as the brain of the control system, managing motion control, I\/O interfaces, and safety-related logic in a deterministic real‑time environment. This specific module is commonly used in machine‑tool installations that rely on a CPU‑centric architecture, delivering dependable program execution and coordination for multi-axis operations typical of milling and turning applications found in industrial manufacturing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268602450154,"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-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6fc5357-0bb23-0aa1-numerical-control-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
