{"product_id":"siemens-6es5948-3ur11-central-processing-unit","title":"Siemens 6ES5948-3UR11 Central Processing Unit","description":"\u003cdiv\u003e\u003cp\u003eThe Siemens 6ES5948-3UR11 CPU948R central processing unit is a dedicated module for the SIMATIC S5-155H controller, delivering 640 KB of RAM to store programs and data and providing essential interfaces for legacy I\/O and communication. This CPU 948R module includes a serial TTY console port and an IFM interface, enabling technician access, diagnostics, and module-to-module communication within classic Siemens S5 automation configurations. Designed specifically for the S5-155H platform, the 6ES5948-3UR11 is used to execute ladder logic and control sequences in older automation systems, making it a common choice for retrofit, maintenance, or repair of legacy machines. The part number 6ES5948-3UR11 uniquely identifies this CPU 948R module within the Siemens SIMATIC S5 family, and it should be matched to the original backplane, I\/O modules, and firmware version to preserve program integrity. Because the S5-155H era architecture predates modern Ethernet, this CPU relies on older fieldbus interfaces and is typically deployed in equipment that still requires S5-compatible control logic.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268521742570,"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-6es5948-3ur11-central-processing-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
