Siemens 6ES7514-2SN03-0AB0 SIMATIC S7-1500 CPU 1514SP F-2 PN 900KB Programmable Logic Controller

The Siemens SIMATIC CPU 1514SP F-2 PN (6ES7514-2SN03-0AB0) is a fail-safe central processing unit for the ET 200SP system with 900 KB of work memory for program and 3.5 MB for data. It provides two PROFINET interfaces, one with an integrated 2-port switch for PROFINET IRT, a 24 V DC supply input, and bit-instruction processing at 6 ns typical.

Technical Specifications

Selection Notes

The F-2 PN designation marks this as the fail-safe variant of the CPU 1514SP family, chosen when the ET 200SP station must execute safety-related logic, F-blocks, alongside standard control rather than the non-fail-safe CPU 1514SP-2 PN. Its 900 KB program / 3.5 MB data memory and support for up to 256 connectable IO devices size it for mid-range distributed stations; a SIMATIC Memory Card and a BusAdapter for the first interface are both required but not included. The dual PROFINET interfaces, one IRT-capable, support a plant network connection and a dedicated I/O ring without an added communication module.

Applications

Used as the controller for ET 200SP-based machine and process stations that combine standard automation with integrated fail-safe logic in a single CPU — packaging lines, material handling cells, and process skids that need both standard I/O control and safety functions without a separate safety PLC.
