Siemens 6ES7414-3FM07-0AB0 SIMATIC S7-400 CPU 414F-3 PN/DP
01Product Profile
Siemens 6ES7414-3FM07-0AB0 is the fail-safe SIMATIC S7-400 CPU 414F-3 PN/DP with 4 MB of work memory divided into 2 MB for code and 2 MB for data. It provides MPI/PROFIBUS DP, Ethernet/PROFINET and an IF 964-DP interface position while adding the hardware basis for an approved S7 F-system application. Safety functionality depends on the complete F-project, F-runtime groups, PROFIsafe devices, signatures, licenses and acceptance process; the article number alone does not establish a validated safety function.

03System Role
Controller Function
- Acts as the central fail-safe controller for combined standard and safety automation tasks.
- Coordinates F-I/O and standard I/O through supported PROFIsafe, PROFIBUS DP and PROFINET architectures.
- Maintains separation and diagnostic handling defined by the S7 F-system configuration.
- Executes the safety program only as part of the licensed, compiled and validated engineering project.
- Provides standard CPU communication while remaining subject to all documented safety restrictions.
Key Capabilities
- Fail-safe CPU hardware supports standard and safety-related program execution in a correctly engineered S7 F system.
- Four megabytes of work memory are divided equally between code and data.
- Integrated PROFINET IO controller functionality supports up to 256 configured IO devices.
- MPI/PROFIBUS DP and the optional IF 964-DP path support additional S7 and fieldbus communication.
- PROFINET functions include shared-device operation and documented isochronous real-time options.
- Safety validation uses the approved F-system engineering workflow, project signatures and acceptance testing.
04Compatibility
- Match the complete 6ES7414-3FM07-0AB0 article; the 3EM standard CPU is not a fail-safe equivalent.
- Use the Siemens-approved STEP 7 and S7 F Systems versions for firmware V7.0 and the installed hardware.
- Verify every F-I/O module, PROFIsafe address, F-parameter set, F-monitoring time and safety signature.
- Confirm MPI, PROFIBUS, PROFINET and optional IF 964-DP configuration separately.
- Retain or migrate the memory card only after confirming type, capacity, project contents and safety documentation.
- A replacement requires the prescribed safety acceptance, proof testing and controlled return to operation.
05Applications
- Safety-related process and manufacturing automation using an approved S7 F-system architecture.
- Machines combining standard PROFINET IO with PROFIsafe field devices.
- S7-400 installations that require both PROFIBUS DP and PROFINET communication.
- Service exchange under a controlled functional-safety maintenance procedure.
- Projects requiring a fail-safe CPU with four megabytes of work memory.
- Lifecycle planning where safety validation records and the original engineering project must be preserved.
06FAQ
What is Siemens 6ES7414-3FM07-0AB0?
It is the fail-safe SIMATIC S7-400 CPU 414F-3 PN/DP for engineered standard and safety-related automation tasks.
How much work memory does it have?
The CPU provides 4 MB total, divided into 2 MB for code and 2 MB for data.
How does it differ from 6ES7414-3EM07-0AB0?
The 3FM article is the fail-safe CPU variant; the 3EM article is the standard CPU and does not provide the same F-system role.
How many PROFINET IO devices can be configured?
The official technical data specifies up to 256 IO devices for the integrated PROFINET IO controller.
Is installing the CPU enough to restore a safety function?
No. The correct F-project, F-I/O, PROFIsafe parameters, signatures, licenses, acceptance procedure and proof tests are mandatory.
What must be tested after replacement?
Validate hardware diagnostics, every network and I/O path, the standard program, all F-runtime groups, safety signatures, stop reactions and the documented safety acceptance tests.
