Features:
- One megabyte of work memory is divided equally between program code and process data.
- X1 carries MPI/PROFIBUS DP, while the two-port X5 interface carries Ethernet/PROFINET.
- The S7-400 backplane supplies operating power and connects the CPU to the central rack.
Siemens 6ES7412-2EK06-0AB0 executes the automation program as a CPU 412-2 PN in the SIMATIC S7-400 family.
Separate work, load, and retained memory areas organize program execution and project storage.
Integrated serial and Ethernet interfaces connect engineering, operator, distributed-I/O, and S7 communication services to the CPU.
The Siemens 6ES7412-2EK06-0AB0 SIMATIC S7-400 CPU 412-2 PN Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Code, Data, and Load Areas
- Work-memory split: 6ES7412-2EK06-0AB0 assigns 512 KB to code and 512 KB to data.
- Execution area: The CPU runs the automation program from work memory.
- Load storage: A SIMATIC RAM or flash card supplies separate load memory up to 64 MB.
- Retention relation: Project storage and live execution use different documented memory areas.
X1 Serial Bus Roles
- Physical path: X1 carries the combined MPI/PROFIBUS DP interface.
- Bus speed: The channel operates at up to 12 Mbit/s.
- Station services: PG/OP, S7, global-data, and DP functions share this configured interface.
- Operating role: 6ES7412-2EK06-0AB0 can use X1 for documented DP master or slave operation.
X5 Ethernet Communication Path
- Two-port interface: X5 provides two Ethernet connections on the integrated PROFINET channel.
- IO roles: The CPU can be configured as a PROFINET IO controller or device.
- Open protocols: TCP/IP, ISO-on-TCP, and UDP use the same integrated Ethernet interface.
- Media function: PROFINET communication also supports the documented media-redundancy function.
Engineering and Runtime Changes
- Engineering basis: STEP 7 V5.5 or higher configures 6ES7412-2EK06-0AB0.
- Runtime changes: Configuration in RUN permits supported hardware changes without a fixed stop-only workflow.
- Isochronous selection: Isochronous operation is assigned through PROFIBUS DP or PROFINET in the project.
- Diagnostic path: System diagnostics and time synchronization follow the configured CPU and interface settings.
