Description

The Siemens S7-1500 CPU 1516-3 PN/DP (catalog number 6ES7516-3AN02-0AB0) is a high-performance controller tailored for complex and data-intensive automation tasks. It combines substantial memory, fast execution speed, and extensive communication capabilities, making it ideal for advanced motion control systems, large-scale machine lines, and multi-station plant automation. Offering 1 MB of work memory (300 KB for the program and 700 KB for data), this CPU is capable of executing large volumes of structured code and managing real-time data flows effectively. It integrates three communication interfaces: two PROFINET ports and one PROFIBUS DP master/slave interface. This dual-protocol capability enables seamless integration of both modern Ethernet-based networks and legacy fieldbus systems, allowing the controller to act as a central node in hybrid industrial architectures. With a 60 ns bit performance speed, the CPU 1516-3 PN/DP executes Boolean instructions rapidly, ensuring accurate and deterministic response in mission-critical applications. It supports all modular S7-1500 expansion components including digital, analog, communication, and technology modules. Advanced diagnostics, trace functions, and system analysis tools are accessible through the integrated web server and the TIA Portal software. Its fanless, rugged housing ensures reliable operation across industrial temperature ranges, while real-time clock and LED indicators support efficient runtime monitoring and error handling.
