Siemens 6ES7516-3TN00-0AB0 CPU Module SIMATIC S7-1500

Siemens 6ES7516-3TN00-0AB0 is a SIMATIC S7-1500T CPU module (CPU 1516T-3 PN/DP) designed for industrial automation tasks requiring integrated multi-network capability. It provides 3 MB of program memory and 7.5 MB of data memory, delivering fast program execution with a 6 ns bit performance, ideal for real-time control. The module offers three communications interfaces: PROFINET IRT with an integrated 2-port switch as the first interface, Ethernet as the second interface, and PROFIBUS as the third interface, enabling versatile network topology and seamless integration with PLC I/O, drives, and field devices. A SIMATIC Memory Card is required for program and data storage, ensuring scalable project development and safe operation. This CPU is built for the SIMATIC S7-1500 architecture, supporting PN/DP connectivity and standard STEP 7 / TIA Portal programming workflows, with diagnostic and configuration capabilities aligned with contemporary industrial controls. Typical applications include machine automation, manufacturing lines, and processes where deterministic timing, remote I/O access, and multi-network communication are essential, making the 1516T-3 PN/DP a capable choice for mid-range control tasks that demand robust performance and scalable connectivity.
