Siemens 6ES7516-3TP10-0AB0 SIMATIC S7-1500T CPU 1516T-3 PN 3MB/25MB Programmable Logic Controller

The Siemens 6ES7516-3TP10-0AB0 is a SIMATIC S7-1500T CPU 1516T-3 PN with 3 MB of integrated program memory and 25 MB of data memory. It carries three PROFINET interfaces, two running PROFINET IRT with an integrated 2-port switch, and supports isochronous mode down to a 250 microsecond distributed cycle for coordinated motion. A SIMATIC Memory Card is required for operation.

Technical Specifications

Selection Notes

The 3 MB program / 25 MB data memory split positions this CPU for mid-size machines that combine standard PLC logic with a limited number of coordinated axes; installations needing more memory or IO capacity should look at the higher-capacity CPU in the same series. Two PROFINET IRT ports with an integrated 2-port switch and isochronous mode down to a 250 microsecond distributed cycle let the 1516T-3 PN run synchronized motion functions such as electronic gearing and camming without a separate motion controller. Two integrated IO Controllers allow one CPU to operate two independent PROFINET IO systems, useful for isolating a fast motion segment from a slower process I/O segment. The CPU ships without a SIMATIC Memory Card, so program storage must be ordered separately.

Applications

Packaging and material-handling machines that combine synchronized axis motion with conventional digital and analog I/O, and PROFINET IRT networks requiring deterministic 250 microsecond to 1 ms update cycles for electronic cam and gearing functions.
