Product description

Siemens 6ES7 444-1MX00-0XE0 is the CP 444 communication processor for the SIMATIC S7-400 automation system. It gives S7-400 controllers access to SIMATIC Industrial Ethernet through the MAP-3.0 protocol profile and handles MMS communication services. The processor can operate as both client and server and supports services including Status, Identify, Read, Write and InformationReport. Ethernet is connected through a screw-fastened 15-pin Sub-D socket conforming to IEEE 802.3. The transmission rate is 10 Mbit/s. Siemens specifies a maximum distance of 50 m between the CP 444 and transceiver using the 727-1 connection cable, or 100 m using Industrial Twisted Pair installation cable. The connected transceiver requires a separate power supply because the interface does not provide transceiver power. The CP 444 can be installed in S7-400 racks UR1, UR2 and CR2 and occupies two slots. Maximum current draw from the backplane bus is 3.1 A, and typical power dissipation is 15.6 W. At 50 x 290 x 210 mm and approx. 2.08 kg, its physical format must be considered during rack and control-cabinet matching. MAP communication is configured with the dedicated CP 444 interface, while function blocks control data transfer and variable services. Before replacement, compare the full order number, installed MAP/MMS communication architecture, slot requirement, cable type, transceiver and STEP-7 parameter set. The documented status and fault indicators on the front also help identify the operating state during commissioning and service without implying additional interfaces on the module. These characteristics make the CP 444 a precise replacement for long-running S7-400 Ethernet connections.

FAQ

Frequently asked questions

Contact us
What is Siemens 6ES7 444-1MX00-0XE0 used for?

The CP 444 connects a SIMATIC S7-400 controller to MAP 3.0 and MMS communication partners through Industrial Ethernet and can provide client and server services.

Which Ethernet interface does the CP 444 provide?

The module operates at 10 Mbit/s in accordance with IEEE 802.3 and uses a screw-fastened 15-pin Sub-D socket for an externally powered transceiver.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
