More Information

Overview Manuals Memory Layout MPI and DP Process Images Rack Operation

Features:

  • A 256 KB work-memory resource is divided equally between program and data.
  • The first interface supports MPI or PROFIBUS DP at rates up to 12 Mbit/s.
  • An isolated second PROFIBUS DP interface supplies a separate distributed-I/O path.
The CPU 412-2 controls S7-400 rack modules and distributed stations from one cyclic program.

Adjustable process images relate cyclic input and output data to the configured peripheral address space.

Backplane power, rack communication and diagnostic records remain tied to the installed S7-400 assembly.

The Siemens 6ES7412-2XG04-0AB0 SIMATIC S7-400 CPU 412-2 may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Separating executable code from runtime data

  • Program section: One half of the work memory contains executable blocks and program structures.
  • Data section: The other half holds data blocks and runtime values used by the program.
  • Load memory: A compatible memory card expands nonvolatile storage for the project.
  • Retention: Battery-backed areas preserve configured values when the rack supply is interrupted.

Assigning the two integrated communication paths

  • First interface: MPI or PROFIBUS DP can connect engineering, operator or distributed stations.
  • Second interface: The isolated PROFIBUS DP port provides a separate fieldbus connection.
  • Bus speed: Each documented PROFIBUS route operates up to 12 Mbit/s.
  • DP stations: The second interface can coordinate the documented number of distributed slaves.

Moving cyclic I/O data through the CPU

  • Input image: Module input states are copied into the process image before program processing.
  • Program access: Logic reads the stored input image and calculates output results.
  • Output image: Calculated states remain in the output image until transfer to the modules.
  • Adjustable size: The image ranges can be expanded to match the configured cyclic address requirement.

Relating backplane resources to CPU status

  • Power source: The CPU receives 5 V DC operating power from the S7-400 backplane.
  • Module exchange: Rack buses carry data between the processor and installed modules.
  • Diagnostic buffer: Recorded events identify processor, module and communication conditions.
  • Front indicators: Status LEDs distinguish operating mode, faults and communication activity.
Description
Siemens 6ES7412-2XG04-0AB0 is the SIMATIC S7-400 CPU 412-2 central processor. It executes the user program, exchanges process data with rack modules and coordinates distributed stations through its integrated communication interfaces.

Working storage in 6ES7412-2XG04-0AB0 is divided between program and data memory, so executable blocks and runtime values occupy defined parts of the same CPU resource. Load-memory cards extend the nonvolatile program store, while battery-backed areas preserve configured data when rack power is removed.

The first interface on 6ES7412-2XG04-0AB0 can serve MPI or PROFIBUS DP communication for engineering, operator access or distributed I/O. Its isolated second PROFIBUS DP interface provides another bus path, allowing field stations to be separated from the programming and peer-communication route.

Process images inside 6ES7412-2XG04-0AB0 collect input states before the program cycle and hold output results until they are transferred to the modules. Their adjustable size relates the cyclic data area to the configured I/O address space rather than forcing every peripheral address into the default image.

Installed in the S7-400 rack, 6ES7412-2XG04-0AB0 takes its operating power from the 5 V backplane and communicates with adjacent modules over the rack buses. Diagnostic buffers and status indicators record processor, communication and module events so a bus fault can be separated from a program stop.
