        More Information

        Overview Manuals Memory Areas PROFINET Roles Program Cycle Display and Diagnosis

        Features:

        • The CPU executes S7-1500 logic with separate program and data work-memory areas.
        • A two-port PROFINET IRT switch connects distributed I/O and controller communication.
        • The display, diagnostic buffer and clock expose controller state independently of field signals.
        The required SIMATIC Memory Card provides load storage for the configured project.

        Executable blocks and runtime data move into their assigned work-memory areas during operation.

        Cyclic process values then pass between the program and PROFINET IO devices through the integrated switch.

        The Siemens 6ES7511-1AK01-0AB0 SIMATIC S7-1500 CPU 1511-1 PN may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Moving a downloaded project into the CPU execution areas

        • Load storage: The required SIMATIC Memory Card holds the loadable project and supplies it to the CPU.
        • Program execution: Executable blocks run from program work memory while the scan is active.
        • Runtime data: Data work memory holds process values and block data read or changed by those instructions.
        • Retention: Only the configured retentive portion survives the documented restart condition; the memory card does not replace runtime work memory.

        Using one integrated interface for two configured controller roles

        • IO controller: The CPU coordinates assigned PROFINET IO devices.
        • IO device: Configured data can be exchanged under another controller.
        • IRT capability: The interface supports isochronous real-time communication.
        • Connections: The integrated interface supplies 64 of the CPU connection resources.

        Moving process data through the S7-1500 scan

        • Input image: Configured inputs enter a process image up to 32 KB.
        • Execution: The CPU runs program logic against memory and input values.
        • Output image: Calculated outputs move into a separate area up to 32 KB.
        • Performance: Bit operations use the documented 60 ns execution time.

        Separating local controller status from network and project information

        • Local view: The front display and keys expose operating and diagnostic information without replacing the downloaded TIA Portal project.
        • Network state: Port LEDs identify physical PROFINET link and traffic, while controller indications report the CPU operating state.
        • Event timing: The hardware clock supplies timestamps used with diagnostic events and retains time for the documented backup period.
        • Engineering context: TIA Portal assigns hardware, addresses, device names and program blocks needed to interpret the states shown locally.
        Description
        Siemens 6ES7511-1AK01-0AB0 is a SIMATIC S7-1500 CPU 1511-1 PN that executes the user program and coordinates distributed automation data over PROFINET IRT. Its integrated two-port switch connects the controller to IO devices and engineering communication without a separate Ethernet module.

        Program blocks run in 150 KB of code memory on 6ES7511-1AK01-0AB0, while 1 MB of data memory holds process values, data blocks and runtime information. A required SIMATIC Memory Card supplies load memory, and the retentive area preserves selected variables across a documented power interruption.

        As a PROFINET IO controller, 6ES7511-1AK01-0AB0 exchanges cyclic input and output data through its two switched ports; as an IO device, it can expose configured data to another controller. Device names, update times and network topology are assigned in the project rather than by the physical port alone.

        A 24 V DC feed powers 6ES7511-1AK01-0AB0, and the front display provides operating, diagnostic and network information without replacing the engineering project. The hardware clock, diagnostic buffer and status LEDs help distinguish program state from supply or PROFINET conditions.

        Technical notes
        A SIMATIC Memory Card is mandatory for Siemens 6ES7511-1AK01-0AB0, and its device name and IP configuration must match the TIA Portal project.
