Siemens SIPLUS S7-1500 CPU 1516-3 PN/DP About

The Siemens SIPLUS S7-1500 CPU 1516-3 PN/DP (6AG1516-3AN02-7AB0) is an exceptionally ruggedized central processing unit engineered to handle large-scale, demanding factory automation tasks with high data throughput in severe industrial environments. Based on the legacy 6ES7516-3AN02-0AB0 platform, this SIPLUS extreme controller features a high-grade conformal coating paired with an integrated heat sink, safeguarding its internal electronics from intense humidity, dust, condensation, and corrosive gases. A defining highlight of this model variant is its extreme thermal resilience, supporting continuous operation across an expanded temperature window from -40 C to +70 C. It manages automated cycles with a rapid execution speed of 10 ns bit performance to ensure highly deterministic control. Onboard system resources provide 1 MB of work memory for user programming alongside 5 MB for runtime 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 DP connectivity. Sourced frequently as a vital spare part for brownfield configurations due to its product cancellation status, it requires a separate SIMATIC Memory Card for operation.
