Siemens 6ES7515-2AM02-0AB0 SIMATIC S7-1500 CPU 1515-2 PN: Specifications, Pricing, and Comparison with Alternatives

Controls engineers selecting a mid-range CPU for a SIMATIC S7-1500 build frequently land on the Siemens 6ES7515-2AM02-0AB0 — a PROFINET IRT-capable processor with 500 KB program memory, 3 MB data memory, and an integrated 2-port switch that eliminates the need for an external network switch in most medium-complexity systems. Before you place an order, there is one critical fact to confirm: this model was cancelled effective October 1, 2024, and has been replaced by 6ES7515-2AN03-0AB0. Depending on whether you are sourcing a spare for an existing installation or specifying a new project, that changes the decision entirely.

If you have already confirmed this is the correct part for your application, check current pricing and availability for the Siemens 6ES7515-2AM02-0AB0 at LeadTime.ca — ships worldwide.

Who Should Buy the 6ES7515-2AM02-0AB0 — and Who Shouldn't

This CPU is the right choice if your project meets all of the following conditions:

  • You require PROFINET IRT with an integrated 2-port switch for direct machine-level connectivity without an external switch
  • Your application fits within 500 KB program memory and 3 MB data memory
  • You need motion control support — up to 7 axes at a 4 ms cycle time or up to 14 axes at an 8 ms cycle time
  • Your operating environment falls within -25°C to +60°C (horizontal) or -25°C to +40°C (vertical)
  • Your STEP 7 TIA Portal toolchain is V17 or higher, which is required for full compatibility with firmware V2.9
  • You are sourcing a spare part for an existing installation — not specifying a new build where the successor model 6ES7515-2AN03-0AB0 is the preferred long-term choice

If your application requires more than 3 MB data memory or you are starting a new project, evaluate the successor model 6ES7515-2AN03-0AB0, or step up to the CPU 1517-3 PN for data-intensive workloads. If PROFINET IRT is not required and cost is the primary driver, the CPU 1511-1 PN is the logical downgrade.

What the SIMATIC S7-1500 CPU 1515-2 PN Actually Does in Your System

The Siemens 6ES7515-2AM02-0AB0 is the central processing unit — the program execution engine — of a SIMATIC S7-1500 automation system. It runs user programs written in STEP 7 TIA Portal, manages all I/O data exchange, handles PROFINET communication with distributed I/O and field devices, and coordinates motion control and process control functions across a connected machine or system. The designation CPU 1515-2 PN tells you two things immediately: this is the 1515 performance tier within the S7-1500 family, and it carries two communication interfaces — a PROFINET IRT interface with integrated 2-port switch plus a second standard Ethernet interface.

The hardware functional status is FS01 and the current firmware version is V2.9. A SIMATIC memory card is not optional — this CPU will not operate without one. With 500 KB of program memory and 3 MB of data memory, the CPU 1515-2 PN sits squarely in the middle of the S7-1500 performance range: more capable than the entry-level CPU 1511-1 PN, and conservatively scaled below the CPU 1517-3 PN which carries 2 MB program memory and 6 MB data memory. The integrated 2,048 IEC counters, 2,048 S7 timers, and support for up to 4 configurable traces at 512 KB per trace give automation engineers practical headroom for diagnostics and data collection without requiring additional hardware.

Typical System Architecture for the CPU 1515-2 PN

The 6ES7515-2AM02-0AB0 sits at the controller tier of a SIMATIC S7-1500 system, sitting between the engineering workstation running TIA Portal and the field devices or distributed I/O modules it manages over PROFINET.

  • Engineering workstation running STEP 7 TIA Portal V17 or higher connects to the CPU via the Ethernet (2nd) interface for program download and diagnostics
  • CPU executes the user program and manages data memory — 500 KB program / 3 MB data — stored on the required SIMATIC memory card
  • PROFINET IRT 1st interface with integrated 2-port switch connects directly to field devices (drives, distributed I/O, HMI panels) in a daisy-chain or star topology without an external switch
  • Distributed I/O modules (such as ET 200MP) connect via the PROFINET IRT interface and are managed by the CPU as remote I/O stations
  • Optional second Ethernet interface supports simultaneous TCP/IP communication for SCADA, MES integration, or remote monitoring on a separate network segment

Where Engineers Deploy the 6ES7515-2AM02-0AB0

In discrete manufacturing, this CPU handles mid-sized conveyor control systems where position-based switching, speed regulation, and reject logic require coordinated I/O across multiple stations. The integrated PROFINET switch is particularly useful here — field devices on the machine can be daisy-chained directly to the CPU without a cabinet-mounted switch.

Packaging machinery is one of the strongest fits for this model. Multi-axis control applications — servo-driven labeling, case packing, and wrapping machines — benefit directly from the motion control capability: up to 7 positioning axes at a 4 ms cycle time, or up to 14 axes at an 8 ms cycle time. The PID compact controller with integrated optimization, PID 3-step controller for valve applications, and PID temperature controller give process engineers flexibility without requiring additional modules.

Assembly line automation with distributed I/O across multiple stations is a textbook deployment for this CPU tier. The isochronous mode support — minimum 500 µs distributed, 1 ms central cycle — enables synchronized control across networked devices where timing accuracy matters. The hardware clock with a 6-week backup at 40°C and a maximum deviation of 10 seconds per day (typical 2 seconds) supports time-stamped data logging and production reporting.

OEM machine builders deploying standalone controllers for saws, presses, or injection molding equipment frequently standardize on this performance tier when they need PROFINET IRT capability without the cost of the CPU 1517-3 PN.

Application Typical Deployment
Mid-sized conveyor control CPU manages position tracking and speed regulation; distributed I/O via PROFINET IRT 2-port switch
Multi-axis packaging machinery Up to 7 servo axes at 4 ms cycle; PID and motion control coordinated in single CPU
Assembly line with distributed I/O ET 200MP stations networked via PROFINET IRT; isochronous mode for synchronized control
OEM standalone machine controller Single CPU with integrated switch; no external network hardware required in cabinet
Batch process automation PID temperature and pressure control with timer/counter-based sequencing; data logging via 4 trace channels

If your architecture specifically requires PROFINET IRT with an integrated 2-port switch and 500 KB program memory is sufficient, the 6ES7515-2AM02-0AB0 is the correct choice for spare part sourcing — check current stock and pricing at LeadTime.ca. For new builds, the successor model 6ES7515-2AN03-0AB0 carries the same interface configuration with updated firmware support.

Expert Verdict: Honest Assessment for Engineers and Procurement Teams

The Siemens 6ES7515-2AM02-0AB0 earned its place as a widely deployed mid-range CPU because it delivers three things simultaneously that were previously hard to get in a single module: PROFINET IRT capability, an integrated 2-port switch, and motion control support for up to 7 axes at 4 ms — all without requiring the higher hardware cost of the CPU 1517-3 PN. For medium-complexity systems with distributed I/O, mixed process and motion requirements, and a need to minimize external network hardware in the cabinet, it is a well-matched solution. The 500 KB program memory and 3 MB data memory are genuine for the majority of mid-size machine programs, and the -25°C to +60°C horizontal operating range covers most industrial cabinet environments without special precautions.

The honest limits are equally worth stating. The 500 KB program memory ceiling becomes a real constraint on larger multi-axis coordinated motion programs, applications with extensive recipe databases, or systems with aggressive real-time data logging requirements. If your program estimate is already approaching that boundary at the design stage, the CPU 1517-3 PN with 2 MB program memory and 6 MB data memory is the responsible upgrade — do not try to optimize a program into a CPU that is genuinely undersized. Additionally, the product cancellation as of October 1, 2024 is a material procurement consideration: for new project specifications, the successor model 6ES7515-2AN03-0AB0 is the correct part to standardize on, as it preserves functional compatibility while providing a supported firmware path forward. The 6ES7515-2AM02-0AB0 remains appropriate for spare part procurement on existing installed systems.

From a procurement standpoint, this CPU sits in the mid-price tier — above the CPU 1511-1 PN entry level and below the 1517-3 PN. Discontinued status means stock availability varies across distributors, and lead times may be extended compared to current-production models. Volume pricing and bundled sourcing with other S7-1500 components are worth discussing before committing to a larger order. If this matches your system requirements, view current stock and pricing at LeadTime.ca.

Wiring and Installation Overview

  • Mount the CPU on a grounded DIN rail; verify cabinet dimensions accommodate 70 mm W × 147 mm H × 129 mm D and that ambient temperature stays within the rated range for the chosen mounting orientation
  • Connect 24 V DC power to CPU terminals — permissible range is 19.2 V to 28.8 V DC; verify your supply can deliver 0.8 A continuous and tolerate a 2.4 A inrush current at startup; reverse polarity protection is present but confirm polarity before applying power
  • Insert the SIMATIC memory card with power OFF — the CPU will not operate without it; push straight in until the latch engages
  • Connect the PROFINET IRT cable (RJ45) to the 1st interface port — the integrated 2-port switch allows direct daisy-chain connection to up to two PROFINET devices without an external switch; connect the 2nd Ethernet interface if simultaneous TCP/IP communication to SCADA or a programming workstation is needed
  • After applying power, verify the RUN/STOP LED is active and the ERROR LED is off before proceeding to software configuration; a 5-second reset window applies if power was removed during operation

Commissioning Overview: Getting the CPU 1515-2 PN Online

  • Open STEP 7 TIA Portal V17 or higher (required for firmware V2.9); create a new project and add the SIMATIC S7-1500 system with CPU 1515-2 PN hardware, selecting FS01 and firmware V2.9 in the device configuration
  • Configure the PROFINET IRT interface settings — IP address, subnet, and gateway — and define the connected PROFINET device topology in the 2-port switch configuration; verify no IP address conflicts exist on the network
  • Write the control program using IEC 61131-3 languages (Ladder, Structured Text, Function Block Diagram); organize code into program blocks and monitor estimated program memory usage against the 500 KB limit before download
  • Download the program via PROFINET or Ethernet, verify firmware version matches project settings, and confirm PROFINET communication with all connected devices using TIA Portal diagnostics
  • Monitor cycle time using the adjustable min/max cycle time monitoring feature; if limits are exceeded, review program complexity or consider offloading logic to ET 200MP distributed I/O modules

Product Cancellation Notice and Upgrade Path to 6ES7515-2AN03-0AB0

The Siemens 6ES7515-2AM02-0AB0 was officially cancelled effective October 1, 2024. It remains available as a spare part through industrial distributors, but it is no longer part of Siemens' active production catalog. The direct replacement for new project specifications is the 6ES7515-2AN03-0AB0, which preserves the CPU 1515-2 PN interface configuration — PROFINET IRT with integrated 2-port switch plus Ethernet — while supporting updated firmware. Engineers maintaining existing SIMATIC S7-1500 installations can continue sourcing the 6ES7515-2AM02-0AB0 as a like-for-like spare; however, confirm firmware version compatibility in TIA Portal before installation. For any new build or system expansion started after 2024, the successor model is the correct specification choice. If you are uncertain which model applies to your scenario, contact the LeadTime.ca team — the team can confirm availability and advise on the upgrade path.

What Engineers Get Wrong When Ordering This Part

Before placing an order for the Siemens 6ES7515-2AM02-0AB0, verify every item on this checklist. These are the most common ordering errors for this model:

  1. Verify PROFINET IRT with 2-port switch is required; other S7-1500 models (1511, 1513, 1517) have different connectivity
  2. Confirm this is NOT a power supply module or I/O terminal; this is the CPU only
  3. Check that 500 KB program memory is adequate (not undersized for application)
  4. Ensure firmware version V2.9 is compatible with your STEP 7 TIA Portal version (V17 or higher recommended for full compatibility)
  5. Verify CPU 1515-2 PN is the correct interface variant; do not confuse with CPU 1515-2F PN (failsafe variant) or CPU 1515-1 PN (standard variant without 2-port switch)
  6. Confirm this model is cancelled as of October 1, 2024; consider upgrade path to 6ES7515-2AN03-0AB0 for new projects

If any item on this checklist raises a question before you order, review the full product details at LeadTime.ca or contact the team directly to confirm the right part for your system.

Frequently Asked Questions

Can I still buy the Siemens 6ES7515-2AM02-0AB0 after the October 2024 cancellation?

Yes — the 6ES7515-2AM02-0AB0 remains available as a spare part through industrial distributors including LeadTime.ca, though stock levels vary and lead times may be longer than for current-production models. For new project specifications, Siemens designates the 6ES7515-2AN03-0AB0 as the successor model. If you are sourcing a replacement for an existing installation, the original part number is still the correct choice — check current availability at LeadTime.ca.

What TIA Portal version is required for the CPU 1515-2 PN with firmware V2.9?

Firmware V2.9 requires STEP 7 TIA Portal V17 or higher for full compatibility. Firmware V2.8 is compatible with TIA Portal V16 or higher. Older TIA Portal versions can access this CPU under model 6ES7515-2AM01-0AB0 with limited functionality. Verify your toolchain version before downloading a program to a CPU with V2.9 firmware.

Is a SIMATIC memory card included with the 6ES7515-2AM02-0AB0?

No. The SIMATIC memory card is a separately ordered component and is required for the CPU to operate — the 6ES7515-2AM02-0AB0 will not function without it. The CPU has one memory card slot. Confirm you have a compatible SIMATIC memory card available before installation.

How many PROFINET axes can the CPU 1515-2 PN control simultaneously?

The 6ES7515-2AM02-0AB0 supports up to 7 positioning axes at a 4 ms cycle time and up to 14 axes at an 8 ms cycle time. Both servo and stepper control are supported. If your application requires 16 axes at 4 ms, the CPU 1517-3 PN is the appropriate upgrade within the S7-1500 family.

What is the difference between the CPU 1515-2 PN and the CPU 1515-2F PN?

The CPU 1515-2F PN is the failsafe variant — it includes integrated safety functions for applications requiring SIL or PLe-rated safety logic. The standard 6ES7515-2AM02-0AB0 (CPU 1515-2 PN) does not include failsafe capability. If your application requires integrated functional safety without a separate safety PLC, you must order the failsafe variant, not this model.

What happens if my 24 V DC supply drops below 19.2 V momentarily?

The CPU 1515-2 PN has a specified voltage failure storage time (mains buffering) of 5 ms. Brief supply interruptions within that window may not cause a program stop, but sustained undervoltage below 19.2 V DC falls outside the permissible supply range. Verify that your power supply is rated to maintain voltage within the 19.2 V to 28.8 V DC permissible range under full load conditions, including the 2.4 A inrush at startup.
