An 18-slot central rack divided into two segments for modular SIMATIC S7-400 hardware.
Siemens 6ES7401-2TA01-0AA0 is the SIMATIC S7-400 CR2 central rack. Siemens documentation defines 18 slots arranged as two segments with 8 or 10 slots, a communication bus extending across both segments and a separated P bus.
For a replacement or system build, verify the exact rack MLFB, installed power-supply arrangement, module allocation and segment plan. Rack geometry and backplane design must be matched before transferring installed S7-400 modules.

Supports layouts that separate the P bus while maintaining the communication bus across both segments.
Fits maintenance projects where the installed nameplate and engineering records identify this exact CR2 rack.
Official Siemens rack documentation confirms the exact product type, but no normalized PLM lifecycle wording and effective date were confirmed in the accessible official sources used for this page.
No Active, Classic, Phase Out Started or Discontinued label is inferred. Reconfirm the current lifecycle for the complete MLFB before procurement.
It is a SIMATIC S7-400 CR2 central rack with 18 slots divided into two segments.
Siemens specifies two segments with either 8 or 10 slots, depending on the segment side.
The communication bus extends across both segments, while the P bus is separated.
No. Rack type, slot count, segmentation, power-supply positions and installed modules must all be verified.

Contact us for availability confirmation, exact-part verification, compatibility checks, warranty details and worldwide delivery planning.
Our service combines exact-part identification, condition review, commercial coordination and export-ready delivery support for legacy automation requirements.
A dedicated contact coordinates identification questions, quotations, document requests and order progress.
The full MLFB, suffix, visible label and requested condition are reviewed before commercial confirmation.
Packing, documentation and routing are organized to support industrial destinations across global markets.
Legacy automation purchasing is rarely solved by matching a short description alone. Similar-looking modules can differ by suffix, hardware revision, protocol support or project configuration. Our workflow keeps the complete order number visible from inquiry through packing and highlights any uncertainty before an order is finalized.
For 6ES7401-2TA01-0AA0, we focus on exact identity, requested condition and evidence appropriate to the available unit. We can coordinate label photographs, enclosure views, connector-condition images and package-content confirmation when these are available from the supply channel. This provides a clearer basis for internal engineering review and purchasing approval.
| Stage | What we check | Customer advantage |
|---|---|---|
| 1. Requirement review | Full model, quantity, condition and destination | Reduces ambiguity at the start of the inquiry. |
| 2. Identity check | MLFB, suffix, family and visible markings | Helps prevent selection of a similar but unsuitable variant. |
| 3. Evidence review | Available photos, connector condition and package scope | Supports engineering and procurement approval before dispatch. |
| 4. Commercial confirmation | Lead time, warranty basis and delivery terms | Creates a clear purchasing record with fewer late surprises. |
| 5. Packing and shipment | Protective packing, labels and shipping documents | Improves handling visibility for international delivery. |
We preserve the complete suffix throughout the quotation and verification process.
New, surplus or professionally refurbished options can be discussed according to your acceptance criteria.
