Siemens 6ES7516-3FN02-0AB0 is a SIMATIC S7-1500F CPU 1516F-3 PN/DP for standard and fail-safe control across PROFINET and PROFIBUS networks. It provides 1.5 MB of program work memory, 5 MB of data memory, an IRT-capable PROFINET interface with two-port switch, a second PROFINET RT interface, and PROFIBUS connectivity. The model is suited to safety-related controller replacement, multi-network machine modernization, and planned lifecycle migration. Before ordering, verify the complete suffix, TIA Portal and safety engineering versions, firmware, memory card, network topology, PROFIBUS settings, safety signatures, and installation constraints.

This CPU is intended for engineered automation projects in which processing capacity, communication architecture and software compatibility are confirmed from the installed system. Selection should be based on the complete order number rather than the CPU family name alone.
Siemens lists this article as cancelled from 1 October 2024 and identifies 6ES7516-3FP03-0AB0 as the successor. Treat migration as an engineered safety change rather than an automatic substitution.
Procurement control: Request clear photos of the product label and compare the full suffix with the existing hardware record.
Capture hardware configuration, safety signatures and installed firmware.
Verify engineering software, memory card and access protection.
Audit PROFINET names, IP settings, PROFIBUS addresses and termination.
Compile standard and safety programs before controlled download.
Perform documented functional and safety validation before production release.
Confirm the complete order number and suffix, both PROFINET interfaces, PROFIBUS requirements where applicable, supply voltage, installed hardware revision, firmware, TIA Portal release, SIMATIC Memory Card, mounting space, network load, original label photos and project backup. For fail-safe CPUs, also verify the safety project, signatures, password handling and validation procedure.
Availability and supply condition vary. Send the complete part number and quantity for confirmation.
Use the exact interface arrangement shown above and verify the installed project before ordering.
Yes. Siemens specifies a SIMATIC Memory Card for this CPU family; confirm the required card and project handling.
Compare the complete suffix, hardware, firmware, engineering software, memory card, network settings and cabinet conditions.
Any lifecycle successor or migration route requires engineering review, project conversion and functional validation.
Yes. Shipping options and documentation are confirmed in the written quotation.
