Siemens 6ES7516-3FN02-0AB0 Programmable Logic Controller

The Siemens 6ES7516-3FN02-0AB0 is equipped with a CPU 1516F-3 PN/DP, providing 1.5 MB of program memory and 5 MB of data memory for handling large automation projects with ease. It supports three onboard communication interfaces—PROFINET IRT with a 2-port switch, PROFINET RT, and PROFIBUS—ensuring seamless integration across both Ethernet-based and legacy fieldbus networks. With a 10 ns bit performance, it delivers ultra-fast processing for time-critical operations, while its failsafe capabilities meet stringent SIL and PL safety requirements without additional hardware. Weighing 0.599 kg and measuring 15.60 x 16.20 x 8.30 cm, it is engineered for space-efficient installation in industrial control cabinets. Manufactured in Germany under the PM400: Phase Out Started classification, it remains supported for existing installations, with continued spare part and service availability. A SIMATIC Memory Card is required for program storage and reliable operation.

In industrial environments, the Siemens 6ES7516-3FN02-0AB0 excels in applications demanding both high-speed performance and integrated safety control. Automotive production lines use it for robotic assembly and welding cells, ensuring synchronized motion and safety interlocking. In process industries such as chemical, pharmaceutical, and oil & gas, it manages critical plant operations while meeting strict safety regulations. Material handling systems benefit from its deterministic communication, coordinating conveyors, sorters, and automated storage solutions with minimal downtime. Its multi-protocol connectivity allows easy integration into existing automation architectures, making it a practical choice for modernizing legacy systems. Even as it enters the phase-out stage, the Siemens 6ES7516-3FN02-0AB0 remains
