Siemens 6ES7516-3UP10-0AB0 SIMATIC S7-1500TF CPU 1516TF-3 PN 3MB/25MB Programmable Logic Controller

The Siemens 6ES7516-3UP10-0AB0 is a SIMATIC S7-1500TF CPU 1516TF-3 PN combining standard, motion, and fail-safe control with 3 MB of program memory and 25 MB of data memory. It carries three PROFINET interfaces, two running PROFINET IRT with an integrated 2-port switch, isochronous mode down to a 250 microsecond distributed cycle, and F-block nesting up to 8 levels for safety logic. A SIMATIC Memory Card is required.

Technical Specifications

Selection Notes

The TF designation adds fail-safe (F) capability on top of the T motion functions of the standard 1516T-3 PN, with F-block nesting extending to 8 levels versus the standard 24-level general nesting. Choose this variant when SIL- or PL-rated safety logic must run on the same CPU that drives isochronous motion, avoiding a separate safety CPU. Memory (3 MB program / 25 MB data) and the two PROFINET IRT ports with 250 microsecond distributed isochronous cycles match the base 1516T-3 PN, so the upgrade cost of the TF variant is limited to unlocking fail-safe engineering in TIA Portal. The CPU still requires a separately ordered SIMATIC Memory Card.

Applications

Machines requiring integrated safety functions (E-stop chains, safety doors, muting) alongside synchronized axis motion on a single S7-1500 CPU, and PROFINET IRT networks needing both isochronous motion and fail-safe PROFIsafe communication.
