Product Overview
The Siemens SIMATIC S7-1500 Compact CPU, model CPU 1511C-1 PN (part number 6ES7511-1CK01-0AB0), is a central processing unit module designed for use in SIMATIC S7-1500 automation systems. It integrates digital and analog I/O and supports PROFINET IRT communication with a 2-port switch. The module offers dedicated program memory (175 kB) and data memory (1 MB) and is configurable via TIA Portal V17 (FW V2.9) or V15 (FW V2.5) and later. Typical use cases include small-to-medium machine control, compact distributed handling systems, and integrated manufacturing cell applications.
