Siemens SIPLUS S7-1500 CPU 1516F-3 PN/DP Rail (Legacy Model) About

The Siemens SIPLUS S7-1500 CPU 1516F-3 PN/DP Rail (6AG2516-3FN02-2AB0) is a high-performance, fail-safe central processing unit custom-engineered to manage massive data throughput and complex safety-critical tasks in demanding railway and rolling stock applications. Based on the legacy 6ES7516-3FN02-0AB0 platform, this rugged SIPLUS extreme controller features an advanced conformal coating that safeguards internal circuitry from severe environmental threats like moisture, conductive dust, and trackside corrosive elements. Meeting strict OT2 railway climate classifications, it functions reliably within an extended operating temperature window spanning from -40 C to +55 C, while safely surviving brief thermal spikes up to +70 C for 10 minutes. The unit executes standard binary logic operations at an ultra-swift 10 ns bit performance speed to maintain highly deterministic safety cycles. Memory resources are precisely optimized, allocating 1.5 MB of work memory for user programming alongside 5 MB for intensive system data management. For comprehensive multi-tier networking, the CPU integrates three versatile communication interfaces: a primary real-time PROFINET IRT port featuring a built-in 2-port switch, a secondary independent PROFINET RT interface, and a third interface providing dedicated PROFIBUS connectivity. Classified under product cancellation status, this space-saving, rail-mounted module requires a separate SIMATIC Memory Card for complete hardware operation.
