01Product Profile

Siemens 6ES7414-2XG02-0AB0 is a legacy SIMATIC S7-400 CPU 414-2 DP with 128 KB of work memory. It combines a multipoint MPI interface with an integrated PROFIBUS DP interface for controller, programming-device and distributed-I/O communication. Because this article belongs to an earlier CPU hardware generation, the exact rack, memory card, STEP 7 project, configured DP network and firmware-compatible communications processors must be reviewed together.

03System Role

Controller Function

  • Acts as the central controller in a standard S7-400 station.
  • Coordinates the central rack and the configured PROFIBUS DP distributed-I/O system.
  • Maintains the installed STEP 7 program, hardware configuration, addresses and diagnostic behavior.
  • Provides the CPU-side communication resources for supported MPI and PROFIBUS connections.
  • Requires the exact memory-card, rack, power-supply and communications-processor arrangement defined by the project.

Key Capabilities

  • Executes the user program and coordinates central and distributed S7-400 I/O.
  • Integrated MPI supports the documented programming, HMI and controller communication functions.
  • Integrated PROFIBUS DP supports a configured distributed-I/O network.
  • The 128 KB work-memory capacity defines the program and data boundary for this exact CPU generation.
  • S7-400 communications processors can be used only when their hardware and firmware combinations are listed as compatible.
  • Module diagnostics and configured interrupt handling support maintenance of the engineered station.

04Compatibility

  • Match the complete 6ES7414-2XG02-0AB0 article number and documented hardware status.
  • Verify the STEP 7 hardware catalog entry, CPU firmware and project backup before any exchange.
  • Confirm MPI address, PROFIBUS DP master configuration, bus parameters, slave diagnostics and termination.
  • Check every communications processor against Siemens compatibility records for this CPU hardware and firmware combination.
  • Do not treat a later CPU 414-2 generation as a drop-in replacement without engineering memory, interface and project migration.
  • Retain the installed S7 memory card only when its type, capacity, contents and compatibility are confirmed.

05Applications

  • Maintenance of legacy S7-400 machines and process skids using CPU 414-2 DP.
  • Standard controller stations with central I/O and PROFIBUS DP devices.
  • Spare-part exchange where the original STEP 7 project and hardware configuration are available.
  • Industrial modernization assessments that require a controlled path from an earlier S7-400 CPU generation.
  • Systems using supported S7-400 communication modules with the exact CPU compatibility combination.
  • Recovery of an installed controller when article number, firmware and memory-card data can be documented.

06FAQ

What is Siemens 6ES7414-2XG02-0AB0?

It is a legacy SIMATIC S7-400 CPU 414-2 DP with 128 KB of work memory and integrated MPI and PROFIBUS DP communication.

How much work memory does it provide?

The exact CPU generation is specified with 128 KB of work memory.

Which integrated interfaces are available?

It includes an MPI multipoint interface and an integrated PROFIBUS DP interface.

Can a newer CPU 414-2 be installed directly?

Not automatically. Memory, firmware, interface behavior, the STEP 7 hardware configuration and communications-processor compatibility must be migrated and tested.

Why is the hardware status important?

Older S7-400 communications processors and firmware combinations are compatibility-specific, so the documented hardware generation must match the project and installed modules.

What should be tested after replacement?

Test CPU startup, memory-card loading, MPI access, PROFIBUS DP communication, all distributed I/O, diagnostics, interrupts and the complete machine sequence.
