Siemens 6ES7511-1UL03-0AB0 SIMATIC S7-1500T CPU 1511TF-1 PN 450KB Programmable Logic Controller

The Siemens SIMATIC S7-1500T CPU 1511TF-1 PN (6ES7511-1UL03-0AB0) is a fail-safe technology CPU with 450 KB program memory and 1.5 MB data memory, a PROFINET IRT interface with an integrated 2-port switch, and 6 ns bit-instruction processing. It supports isochronous mode down to 500 microseconds distributed and requires a SIMATIC Memory Card.

Technical Specifications

Selection Notes

The TF in the designation marks this as a fail-safe (F) plus technology (T) CPU: F-blocks nest up to 8 deep within the CPU's 24-level nesting budget, and the T function adds isochronous motion-control OBs on top of standard S7-1500 logic. At 6 ns per bit instruction and 37 ns for floating point, 450 KB program plus 1.5 MB data memory suits a mid-size machine running several coordinated axes rather than a simple I/O-only station. The integrated 2-port PROFINET switch lets distributed I/O daisy-chain without an external switch, and IRT support down to a 250 microsecond send cycle is what keeps closed-loop motion control deterministic on this CPU.

Applications

Fits machines that combine safety functions with coordinated multi-axis motion over PROFINET IRT: packaging and converting lines, handling systems with several synchronized axes, and safety-rated production cells where fail-safe logic and motion control run on the same CPU.
