Siemens 6ES7511-1TK01-0AB0 is a SIMATIC S7-1500T CPU 1511T-1 PN central processing unit supplied as a spare-part article. It combines 225 KB of program work memory, 1 MB of data work memory and technology functions for positioning, gearing, cam and kinematics tasks in one 35 mm-wide CPU.
For the field network, Siemens 6ES7511-1TK01-0AB0 provides one PROFINET IRT interface with an integrated two-port switch. The controller can run distributed isochronous operation with a minimum 625 µs OB 6x cycle, while central isochronous operation uses a minimum 1 ms cycle; the project, drive clocks and I/O update times must therefore be coordinated rather than configured independently.
During commissioning, Siemens 6ES7511-1TK01-0AB0 requires a SIMATIC Memory Card and a 24 V DC supply within 19.2–28.8 V. Its 3.45 cm display, six keys and mode selector provide local status and control access, while the hardware configuration and motion objects remain in the STEP 7 TIA Portal project.
