Product Details

SIMATIC S7-400 / CENTRAL PROCESSING UNIT

SIEMENS 6ES7412-2XK07-0AB0

The 6ES7412-2XK07-0AB0 is a SIMATIC S7-400 CPU 412-2 for modular automation systems. It executes the control program, manages central and distributed I/O and provides integrated MPI/PROFIBUS DP communication paths.

PRIMARY ROLE

CPU 412-2

Its two integrated interfaces support programming, HMI and distributed I/O architectures. Replacement planning must preserve memory-card content, hardware configuration, network addresses and the surrounding S7-400 rack arrangement.

SYSTEM RELATIONSHIP

CPU, Rack, Memory and PROFIBUS in One Control Layer

The CPU 412-2 operates in an S7-400 central rack with a suitable power supply and backplane bus. Signal modules and communication processors extend the local station, while PROFIBUS DP links distributed devices. A replacement must match firmware, project requirements, memory card, interface configuration and installed option modules.

Member	Role	Selection Difference
CPU 412-2	Entry CPU in the compared S7-400 range	1 MB work memory and two integrated bus interfaces
CPU 414 family	Higher processing and memory capacity	Used when program scale and communication load exceed CPU 412 requirements
CPU 416 family	Higher-performance S7-400 control	For larger and more demanding automation tasks
S7-400 rack / PS / memory card	Required system partners	Must match power demand, project size and installed module layout

PURCHASE QUESTIONS

FAQ for 6ES7412-2XK07-0AB0

Can 6ES7412-2XK07-0AB0 be installed without moving the memory card?

The CPU and memory-card strategy must follow the existing project. Back up the program and hardware configuration, confirm the correct card type and capacity, and use a controlled startup procedure.

What must be compared when replacing an older CPU with 6ES7412-2XK07-0AB0?

Compare firmware, STEP 7 hardware support, memory requirements, rack and power-supply compatibility, MPI/DP addresses, PROFIBUS configuration and communication processors.

Does 6ES7412-2XK07-0AB0 provide Ethernet communication?

Its integrated interfaces are MPI/PROFIBUS DP and PROFIBUS DP. Ethernet requires a compatible S7-400 communication processor or another supported system path.

How can downtime be reduced when changing 6ES7412-2XK07-0AB0?

Prepare a verified backup, record switch and address settings, label every connector, confirm the memory card and spare revision, and test communications before releasing outputs.

What condition checks are important for a used 6ES7412-2XK07-0AB0?

Inspect the complete label, front connectors, backplane contacts, memory-card slot, mode selector and signs of heat or contamination. Confirm that no bent pins or cracked retainers are present.
