Description

The Siemens S7-1500 CPU 1517F-3 PN/DP (catalog number 6ES7517-3FP00-0AB0) is a high-end, fail-safe programmable logic controller tailored for large-scale automation systems where safety and speed are equally critical. With its integrated safety functionality up to SIL 3 (IEC 62061) and PL e (ISO 13849-1), this controller can simultaneously run both standard and safety programs on one CPU—ideal for applications in automotive, chemical, pharmaceutical, and large machinery sectors. This model features a generous 2 MB work memory, split into 700 KB for the user program and 1.3 MB for data, making it suitable for extensive automation projects involving high channel counts, fast logic execution, and modular safety integration. Processing speed for bit instructions is 1 ns, ensuring real-time responsiveness in complex control loops or interlocked safety systems. Communication-wise, the CPU 1517F-3 PN/DP is equipped with dual PROFINET ports and one PROFIBUS DP interface. This makes it ideal for hybrid automation architectures requiring integration with field devices, distributed I/O stations, and legacy systems. Safety functions such as emergency stop, protective door monitoring, and two-hand control are programmed using TIA Portal with STEP 7 Safety Advanced. As with other S7-1500 models, this fail-safe CPU includes diagnostics, integrated web server tools, and trace capabilities for maintenance and commissioning. With no moving parts and DIN rail mounting, it offers reliable long-term service in demanding environments requiring both operational control and functional safety.
