Description

The Siemens S7-1500 CPU 1517-3 PN/DP (catalog number 6ES7517-3AP00-0AB0) is a premium-class controller built for large-scale and performance-intensive automation environments. Designed for applications that demand high memory capacity, fast execution cycles, and robust network connectivity, this CPU is well-suited for process automation, packaging lines, high-speed assembly systems, and distributed plant architectures. The CPU offers 2 MB of total work memory—700 KB for the user program and 1.3 MB for data—allowing for extremely complex control logic, high-volume data processing, and scalable modular configurations. It features two integrated PROFINET ports and one PROFIBUS DP interface, enabling hybrid communication across Ethernet and fieldbus networks. This makes the CPU a central integration point for distributed I/O systems, legacy equipment, high-speed drives, and third-party devices. With a processing speed of 1 ns for bit operations, the 1517-3 PN/DP stands out for its fast response time and deterministic performance. As with other S7-1500 models, it supports modular expansion with signal, communication, and function modules. The controller includes extended diagnostics, trace functions, and a built-in web server, all accessible through the TIA Portal. Rugged, compact, and fanless, the CPU 1517-3 PN/DP is ideal for industrial facilities that require top-tier processing capabilities and connectivity without compromising reliability or ease of maintenance.
