Product description

Siemens 6GK7 343-1CX10-0XE0 is a CP 343-1 Lean communications processor from the SIMATIC NET family. It connects controllers from the SIMATIC S7-300 and C7-300 ranges to Industrial Ethernet and PROFINET. Two RJ45 ports with a transmission rate of 10–100 Mbit/s and an integrated 2-port ERTEC 200 switch are available for this purpose. Documented communication services include TCP/IP, UDP, multicast, SEND/RECEIVE with and without RFC1006, Fetch/Write and S7 communication as a server. The CP can also operate as a PROFINET IO Device. The external supply is 24 V DC; the module additionally uses 5 V DC from the S7-300 backplane bus. Typical current consumption is 0.16 A from the external 24-V supply and 0.2 A from the backplane bus. Maximum external current consumption is 0.2 A, and power loss is 5.8 W. With a width of 40 mm, height of 125 mm, depth of 120 mm and net weight of 0.22 kg, the unit is a compact single-width S7-300 module. Its protection class is IP20. Documented operating temperatures are 0–60 °C with a horizontal rail arrangement and 0–40 °C for vertical installation. The complete order number must be checked carefully before replacement because other CP-343-1 versions can provide different communication functions and connection capacities despite a similar enclosure. Also compare the hardware product version, firmware version, STEP-7 configuration, IP address, subnet, connection resources and PROFINET device name. The module is suitable for maintenance, repair and spare-parts inventory in existing SIMATIC networks. Installation and commissioning may only be performed by qualified personnel; the configuration and network parameters must be backed up before module replacement.

FAQ

Frequently asked questions

Contact us
What is the function of Siemens 6GK7 343-1CX10-0XE0?

CP 343-1 Lean connects SIMATIC S7-300 or C7-300 to Industrial Ethernet through two RJ45 ports and can operate as a PROFINET IO Device.

What should be checked before replacing CP 343-1 Lean?

Compare the order number, hardware version, firmware, STEP-7 configuration, IP address, subnet, connection resources and PROFINET device name, and back up the configuration.

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.
