Siemens 6ES7511-1FK02-0AB0 Programmable Logic Controller Module

Siemens 6ES7511-1FK02-0AB0 is a SIMATIC S7-1500F CPU module (CPU 1511F-1 PN) designed for compact, high-performance PLC control. It provides 225 KB of program memory and 1 MB of data memory, enabling efficient storage of logic and runtime data. The unit features a PROFINET IRT interface with a built-in 2-port switch and delivers 60 ns bit performance for fast, deterministic Ethernet communication. A SIMATIC Memory Card is required to load programs and store data, and the module is designed for 24 V DC operation. Networking is supported by two RJ45 interfaces, aligning with the S7-1500F family’s dual-port Ethernet design. This part is cataloged as a spare part, and Siemens notes a successor: 6ES7511-1FL03-0AB0; older STEP 7 or TIA Portal configurations can target this model as 6ES7511-1FK01-0AB0 depending on portal compatibility.
