Features:
- CPU 413-2 DP executes the SIMATIC S7-400 station program from a 72 KB working-memory area.
- The MPI interface provides a multipoint path for engineering, operator and controller communication.
- Integrated PROFIBUS DP connects the central CPU to configured distributed fieldbus stations.
The processor occupies the central controller role, coordinating cyclic logic with the station's rack and bus resources.
MPI and PROFIBUS DP are separate communication paths, so each interface can be assigned to its intended network participants.
Active code and controller data share the documented working-memory capacity during program execution.
The Siemens 6ES7413-2XG02-0AB0 SIMATIC S7-400 CPU 413-2 DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the processor fits the S7-400 station
- Program execution: CPU 413-2 DP runs the user program and coordinates updates between rack resources and distributed I/O.
- Central position: The processor provides the control point for the configured S7-400 station rather than acting as a stand-alone field device.
- Working data: Active code and data use the 72 KB working-memory area while the CPU is in operation.
- Station project: Rack modules and bus participants must match the hardware configuration assigned to the processor.
Multipoint access to the controller
- Engineering connection: MPI provides a direct path for programming and diagnostic access to the CPU.
- Operator link: Compatible operator devices can share the multipoint network when their addresses and bus settings are configured.
- Controller exchange: S7 communication can use the MPI path without replacing the fieldbus role of PROFIBUS DP.
- Network separation: MPI parameters are configured independently from the integrated DP master segment.
Cyclic exchange with distributed stations
- DP interface: The integrated bus connection links the CPU to configured PROFIBUS DP nodes.
- Process image: Input data enters the controller program and output data returns to field devices through the assigned DP addresses.
- Bus project: Station addresses, baud rate and participant order must agree with the STEP 7 hardware configuration.
- Fault isolation: DP diagnostics identify bus-participant or segment problems separately from MPI engineering access.
Working-memory planning
- Capacity boundary: The 72 KB area must accommodate the active program and controller data required by the application.
- Download check: The compiled project must fit the documented CPU capacity before transfer.
- Runtime role: Working memory supplies the instructions and data used during cyclic execution.
- Change control: Program expansion should be checked against available memory rather than inferred from another CPU 413 variant.
