01Key Information
Siemens 6ES7416-2XL01-0AB0 is an earlier SIMATIC S7-400 CPU 416-2 DP generation with 1.6 MB of work memory. It provides the controller functions for a central S7-400 station and integrated MPI/PROFIBUS DP communication. Siemens documentation identifies hardware version 9 and classifies the CPU among older controllers that require specific handling for ET 200iSP integration, so the original STEP 7 project and fieldbus design are essential replacement references.

02Functions
Core Functions
- Executes the S7-400 user program and coordinates central and distributed process I/O.
- Provides 1.6 MB of work memory for the documented CPU 416-2 generation.
- Supports MPI communication for programming-device, HMI and controller access.
- Supports PROFIBUS DP communication for configured distributed-I/O stations.
- Can be used with only those S7-400 communication processors released for this hardware generation.
- Maintains the diagnostic, interrupt and timing behavior defined in the original STEP 7 hardware configuration.
Product Identity

04Installation
- Record the nameplate, hardware version, memory card and all rack-module positions before removal.
- Back up the complete STEP 7 program and hardware configuration using the installed engineering environment.
- Document MPI and PROFIBUS addresses, baud rate, termination, diagnostic mapping and all distributed stations.
- For ET 200iSP projects, preserve the documented GSD-based integration and SIMATIC PDM parameterization because this older CPU does not support DPV1 operation for that station.
- Verify every Ethernet and PROFIBUS communication processor against Siemens CPU compatibility records.
- After exchange, test startup, program loading, MPI access, PROFIBUS communication, diagnostics and the full process sequence.
05Lifecycle
- Siemens documentation identifies this article as an older CPU generation.
- No automatic successor is asserted because migration depends on memory, STEP 7 configuration, fieldbus functions and installed communication processors.
- Confirm Siemens repair or spare-part availability before planning an outage.
- Preserve the original project, GSD files, PDM parameters and memory-card image for lifecycle support.
- Any upgrade to a later S7-400 or S7-1500 controller requires an engineered hardware and software migration.
