More Information

Overview Manuals Redundant Pair Bus Assignment Backup Chain Rack Boundary

Features:

  • Two synchronization-module interfaces connect the CPU to its redundant H-system partner.
  • MPI/DP, a second PROFIBUS DP path, and switched PROFINET divide programming, fieldbus, and Ethernet IO traffic.
  • Program and data each receive 512 KB of work memory, with separate card-based load-memory expansion.
Siemens 6ES7412-5HK06-0AB0 combines program execution and partner synchronization in a two-slot S7-400H processor.

The interface layout of 6ES7412-5HK06-0AB0 allows operator or programming access, two DP relationships, and a PROFINET IO network to coexist.

Backplane power, memory-card choice, battery backup, and matching synchronization hardware define the rack boundary around 6ES7412-5HK06-0AB0.

The Siemens 6ES7412-5HK06-0AB0 CPU 412-5H PN/DP may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the partner CPUs stay coordinated

  • CPU partners: An H-system uses matching processors rather than treating one CPU as a passive spare.
  • Sync modules: The two dedicated positions accept synchronization hardware that carries partner-state exchange.
  • Fiber links: Synchronization cables connect the paired module paths according to the selected distance hardware.
  • Project identity: Rack, CPU, firmware, and synchronization assignments must match on both sides before redundant operation.

Separating station traffic

  • MPI/DP port: Engineering devices, operator stations, and one DP segment share the integrated multipurpose interface.
  • Dedicated DP: The second PROFIBUS interface forms another master path with its own configured stations.
  • PROFINET IO: The switched Ethernet interface connects the CPU to its assigned IO devices and communication peers.
  • Partner sync: Redundancy data avoids those plant networks by using the dedicated synchronization path.

Working, load, and retained data

  • Work memory: Program and runtime data execute from separate 512 KB allocations.
  • Load card: FLASH or RAM cards extend the project storage area up to the documented 64 MB limit.
  • Battery role: The rack battery retains backed-up working data and RAM-card content when system power is removed.
  • External backup: The CPU also exposes the documented external backup-voltage path for the retention circuit.

Power, slots, and engineering

  • Slot width: The processor occupies two adjacent S7-400 rack positions.
  • Power path: Operating power arrives from the system supply through the backplane rather than a separate CPU feed.
  • Interface current: Each DP interface has its own stated current allowance for connected interface loads.
  • STEP 7 baseline: Hardware configuration starts with STEP 7 V5.5 SP2 HF1 for this V6.0 CPU.
Description
Siemens 6ES7412-5HK06-0AB0 is a SIMATIC S7-400H CPU 412-5H PN/DP central processing unit for S7-400H and S7-400F/FH stations. It executes the automation program and exchanges operating state with the partner CPU through the H-system synchronization paths.

Five interface functions organize the external and redundant data paths of 6ES7412-5HK06-0AB0. One MPI/PROFIBUS DP port serves programming, operator, and DP communication; a second PROFIBUS interface provides another DP-master path; the switched PROFINET connection handles Ethernet IO; and two synchronization-module positions exchange H-system state between partner CPUs.

The 1 MB work memory of 6ES7412-5HK06-0AB0 is divided equally between program and data. Load memory expands through a FLASH or RAM memory card up to 64 MB, while battery-backed operation retains the working and RAM-card contents under the documented backup conditions.

Power reaches 6ES7412-5HK06-0AB0 through the S7-400 system power supply and backplane rather than a separate 24 V controller input. The CPU draws 5 V backplane current for its own operation, while the DP interfaces have separately stated current available for connected interface loads.

STEP 7 V5.5 SP2 with HF1 is the listed engineering baseline for 6ES7412-5HK06-0AB0. The hardware occupies two rack slots and uses firmware V6.0, so rack space, project hardware catalog, synchronization hardware, and partner-CPU configuration must agree before an H-system can enter redundant operation.

Technical notes
Siemens 6ES7412-5HK06-0AB0 is a two-slot CPU 412-5H that links redundant synchronization with MPI/DP, PROFIBUS, and switched PROFINET communication.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must match between the two CPUs paired with 6ES7412-5HK06-0AB0?
The 6ES7412-5HK06-0AB0 partner arrangement should match CPU order number, firmware, project configuration, synchronization modules, and link hardware.
Why are there two synchronization-module positions on 6ES7412-5HK06-0AB0?
The paired paths on 6ES7412-5HK06-0AB0 carry redundant partner synchronization through the selected module and fiber arrangement.
Does 6ES7412-5HK06-0AB0 need a separate 24 V DC power input?
No. The 6ES7412-5HK06-0AB0 receives operating power from the S7-400 system power supply through the rack backplane.
Can one memory-card type be assumed for every 6ES7412-5HK06-0AB0 project?
No. Choose FLASH or RAM for the 6ES7412-5HK06-0AB0 load-memory and retention requirement, then keep the card within the 64 MB limit.
How should the two PROFIBUS paths on 6ES7412-5HK06-0AB0 be documented?
Record the MPI/DP segment and dedicated DP segment of 6ES7412-5HK06-0AB0 separately, including addresses, baud rate, and assigned stations.
Where should diagnosis begin if a 6ES7412-5HK06-0AB0 H-system will not become redundant?
Start with 6ES7412-5HK06-0AB0 partner diagnostics, then check firmware, project equality, synchronization modules, fiber links, and rack states.
