Siemens 6ES7517-3UQ10-0AB0 SIMATIC S7-1500TF CPU 1517TF-3 PN 6MB/50MB Programmable Logic Controller

The Siemens 6ES7517-3UQ10-0AB0 is a SIMATIC S7-1500TF CPU 1517TF-3 PN with 6 MB of program memory and 50 MB of data memory, combining standard, motion, and fail-safe control. It carries three PROFINET interfaces, two running PROFINET IRT with an integrated 2-port switch, a 0.6 ns typical bit-operation time, and connects up to 1661 distributed IO devices. A SIMATIC Memory Card is required.

Technical Specifications

Selection Notes

Against the 1516TF-3 PN, this CPU doubles program memory to 6 MB and data memory to 50 MB, halves typical bit-operation time to 0.6 ns, and doubles the CPU-block element count to 20 000, giving headroom for larger programs and more axes. The addressable IO module count rises to 16 384 with up to 1 661 distributed IO devices supported, so it fits machines or lines with a large PROFINET topology rather than a single cell. Fail-safe F-blocks are available as in the 1516TF-3 PN, so choose this CPU over the smaller 1516TF-3 PN when program size, IO device count, or cycle-time headroom on the smaller CPU becomes the limiting factor. A SIMATIC Memory Card must be ordered separately.

Applications

Larger synchronized-motion machines and lines that combine fail-safe logic with a wide PROFINET IO footprint, and applications needing faster cycle times than the 1516TF-3 PN can deliver under equivalent load.
