6ES7511-1AK02-0AB0 is the SIMATIC S7-1500 CPU 1511-1 PN central processing unit. It provides 150 kB of program work memory, 1 MB of data work memory and a 60 ns bit-operation time for compact automation tasks.

The integrated PROFINET IRT interface includes a two-port switch for network integration. A SIMATIC Memory Card is required, and the FS03 hardware version is associated with firmware V2.9 engineering in TIA Portal V17.

• Executes compact S7-1500 control applications with separate program and data work-memory areas.
• Provides PROFINET IRT communication through an integrated two-port switch.
• Supports identification and maintenance data from I&M0 through I&M3.
• Supports distributed and central isochronous operation within the documented cycle boundaries.
• Uses a removable SIMATIC Memory Card for the automation project and device data.
• Provides integrated display and operating keys for local status and service access.

• Compact SIMATIC S7-1500 machine and process-control systems using one PROFINET network interface.
• PROFINET IRT automation cells that use the CPU integrated two-port switch.
• Installed CPU 1511-1 PN systems requiring an FS03 spare-part replacement.
• Projects engineered with the supported TIA Portal and firmware combination.

• The submitted shortened code 511-1AK02-0AB0 is completed to the Siemens article number 6ES7511-1AK02-0AB0 for this preview.
• This article is identified as a spare part, with 6ES7511-1AL03-0AB0 listed as the successor product.
• Back up the SIMATIC Memory Card, CPU project, device name, IP configuration and protection settings before replacement.
• Confirm the hardware status, firmware and TIA Portal engineering version before loading the project.
• Validate PROFINET device communication, diagnostics and controlled-machine functions after commissioning.
