Features:
- Provides 128 KB working memory for S7-400 control programs.
- Uses an integrated MPI interface for engineering and S7 communication.
- Coordinates modular signal and communication hardware in the central rack.
The XG02 article is the single-interface CPU 414-1 execution, not a multi-network CPU variant.
It processes the plant program and schedules rack I/O, timed events and diagnostic responses.
An exact spare decision requires the STEP 7 archive, memory medium and the complete fitted-rack inventory.
The cancelled CPU is available only through confirmed legacy sourcing channels.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Maintain process or machine control in a legacy S7-400 central rack.
- Support MPI-connected engineering devices and operator interfaces.
- Preserve an installed application while a replacement architecture is designed.
- The CPU operates within the SIMATIC S7-400 rack and backplane architecture.
- Signal modules and communication processors must remain supported by the archived project.
- A different CPU family requires analysis of memory, interfaces, and instruction compatibility.
- Cyclic organization blocks process the input image and calculate output states.
- Interrupt and diagnostic organization blocks handle events outside the normal scan sequence.
- STEP 7 defines the hardware configuration and downloadable user program.
- The archived project must preserve the exact CPU order number and released firmware level.
- Firmware-dependent hardware-catalog selection must be checked before restoring the controller.
- Siemens lists no direct replacement, so a platform migration requires a separately validated project update.
