PRODUCT DESCRIPTION
6ES7401-2TA01-0AA0 Segmented Central Mounting Rack
Siemens 6ES7401-2TA01-0AA0 is the CR2 central rack for SIMATIC S7-400 automation. It provides eighteen module positions in two segments for a configured controller station, with support for two redundant power-supply modules.
The rack divides its peripheral bus into eight-slot and ten-slot segments, while the communication bus continues across both segments. This arrangement supports the documented module and CPU allocation of the station. The rack operates within a 0–60 ℃ ambient range; module selection, power balance and slot assignments determine the completed system configuration.

SYSTEM INTEGRATION
Integrate 6ES7401-2TA01-0AA0 segmented central mounting rack
Plan the CR2 station as eighteen positions divided into eight-slot and ten-slot segments. Select CPUs and modules that support the documented rack allocation; the rack itself does not execute a control program.
Check the separated peripheral buses, continuous communication bus and redundant power-supply arrangement against the S7-400 hardware configuration. Determine power capacity from the selected supplies and installed modules.
Follow the applicable S7-400 hardware instructions for assembly and acceptance. Verify segment allocation, module identification and the downloaded station configuration before performing controlled communication and process checks.
Features:
- Total module positions: 18 slots
- Rack segment allocation: 2 segments; 8 and 10 slots
- Redundant power-supply capacity: 2 PS modules
The 6ES7401-2TA01-0AA0 segmented central mounting rack requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify 6ES7401-2TA01-0AA0 segmented central mounting rack
Confirm the full 6ES7401-2TA01-0AA0 identity and CR2 segmented arrangement before replacing the rack. An eighteen-slot rack with a different bus arrangement is not established as equivalent.
Document every module position, segment boundary, power-supply connection and interconnection before dismantling. Preserve the controller project and compare the replacement mechanical and bus layout with the recorded station.
Reassemble the verified station and check both peripheral-bus segments and communication continuity. Confirm module recognition and the intended redundant-supply behaviour before restoring normal operation.
Features:
- Total module positions: 18 slots
- Rack segment allocation: 2 segments; 8 and 10 slots
- Redundant power-supply capacity: 2 PS modules
The 6ES7401-2TA01-0AA0 segmented central mounting rack requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7401-2TA01-0AA0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How are the eighteen CR2 slots divided?
The rack has two segments with eight and ten slots. Use the applicable S7-400 configuration rules to allocate CPUs, supplies and I/O modules. -
Which bus remains continuous across the CR2 segments?
The communication bus continues across both segments. The peripheral bus is separated between them. -
How many redundant supply modules can this rack accept?
The exact datasheet states that two redundant power-supply modules can be plugged in. The selected supplies and station configuration determine usable power. -
Does the central rack perform CPU control functions?
No. 6ES7401-2TA01-0AA0 provides the mechanical and bus arrangement; the installed CPU and configured modules perform the automation functions. -
What operating and storage temperatures are documented for CR2?
Operation is specified from 0 to 60 ℃, and storage or transportation from 0 to 70 ℃. Verify the limits of each fitted module as well. -
Can a continuous eighteen-slot rack substitute for this segmented article?
The same slot count alone is insufficient. Confirm the separated peripheral-bus requirement and full CR2 article identity before selecting a replacement. -
Which rack arrangement details should be included in a CR2 enquiry?
Provide 6ES7401-2TA01-0AA0, the existing eight/ten-slot allocation, installed power-supply codes and module-position schedule, plus the quantity required. -
What should receiving inspection examine on this central rack?
Compare the article label, eighteen positions, segment arrangement and backplane connector condition. Inspect the frame for damage and match the supplied rack to the recorded station.
