Features:

  • Bridge Between the STEP 7 Engineering Environment and S7-400 Rack Backplane
  • Integrates 512 KB Work Memory with Dual-Interface Communication Support
  • Functions in Coordination with MPI/DP Networks and Standard S7-400 I/O Modules
The 6ES7412-2XJ05-0AB0 serves as the CPU 412-2 central processing unit in a SIMATIC S7-400 rack, providing reliable execution of control programs for all modules within the system. It continuously processes automation logic using its 512 KB work memory (256 KB code, 256 KB data) and distributes instructions through the rack backplane to support steady-state operation of all I/O modules and function modules. Seamless communication handling is standard with the 6ES7412-2XJ05-0AB0, and utilizing the optional PROFIBUS DP interface enables high-speed deterministic data exchange with distributed field devices.

The 6ES7412-2XJ05-0AB0 provides essential processing functions common to the entire rack, and is a critical component of the control path, directly affecting the proper, normal operation of the overall automation system. One 6ES7412-2XJ05-0AB0 CPU module is required per rack as the central processing unit. The 6ES7412-2XJ05-0AB0 occupies its designated slot position in the rack and is always installed in the CPU slot (central controller position, the dedicated processor slot).

For expanded communication requirements, the S7-400 System can utilize the second interface of the 6ES7412-2XJ05-0AB0 for dedicated PROFIBUS DP connectivity. In addition to standard MPI/DP operation, the dual-interface configuration also enables parallel network segmentation. The 6ES7412-2XJ05-0AB0 dual-interface configuration executes communication routing using the internal circuitry specified in the CPU options. Using this method, the communication system continually monitors the status of both interfaces.

The 6ES7412-2XJ05-0AB0 SIEMENS CPU Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
