Product description

Siemens 6GK7 443-5FX02-0XE0 is the CP 443-5 Basic communication processor for SIMATIC-S7-400 systems. It connects the S7-400 station to PROFIBUS and provides PG/OP communication, S7 communication, open communication through SEND/RECEIVE and PROFIBUS FMS. This makes it relevant to existing systems that must retain classic fieldbus communication, operator and programming access, or data exchange between controllers. The PROFIBUS interface supports transmission rates from 9.6 kbit/s to 12 Mbit/s and uses a 9-pin Sub-D socket with RS-485. Power is supplied at 5 V DC through the S7-400 backplane bus; Siemens specifies typical current consumption of 1 A and power dissipation of 5 W. The compact S7-400 module occupies one standard-width slot, measures 25 x 290 x 210 mm and has a net weight of 0.65 kg. For engineering, Siemens specifies up to 32 open SEND/RECEIVE connections with up to 240 bytes of user data per connection, up to 48 S7 connections and up to 48 FMS connections. Configuration uses STEP 7 V5.2 SP1 or later with NCM S7 for PROFIBUS. The CP also supports time synchronization, S7 routing and operation in high-availability S7-400H systems. According to the device manual, this version can replace 6GK7 443-5FX01-0XE0 and 6GK7 443-5FX00-0XE0; the hardware configuration, CPU compatibility, bus parameters and project version must still be checked before replacement. The documented limits and exact Siemens order number support rapid technical assessment and precise restoration of PROFIBUS communication without unnecessary changes to the existing S7-400 architecture.

FAQ

Frequently asked questions

Contact us
What is Siemens 6GK7 443-5FX02-0XE0 used for?

The CP 443-5 Basic connects SIMATIC S7-400 stations to PROFIBUS and supports PG/OP, S7, SEND/RECEIVE and PROFIBUS FMS communication.

Can the CP 443-5 Basic replace earlier versions?

Siemens identifies 6GK7 443-5FX02-0XE0 as a replacement for 6GK7 443-5FX01-0XE0 and 6GK7 443-5FX00-0XE0. Before replacement, compare the hardware configuration, CPU, bus parameters and engineering project.

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.
