Siemens 6GK7343-1CX10-0XE0 · SIMATIC S7-300 · Industrial Ethernet · Dual RJ45
Siemens 6GK7343-1CX10-0XE0 is a SIMATIC NET CP 343-1 Lean communications processor for connecting S7-300 controllers to Industrial Ethernet. It supports TCP/IP, UDP, multicast, SEND/RECEIVE with or without RFC1006, Fetch/Write, S7 communication server functions and operation as a PROFINET IO device. The integrated ERTEC 200 two-port switch provides two 10/100 Mbit/s RJ45 connections, while SNMP diagnostics and LAN initialization support commissioning and maintenance. Before replacement, buyers should compare the complete suffix, hardware and firmware version, STEP 7 configuration, external 24 V supply, RJ45 topology and approved successor strategy.

This exact order code should not be treated as universally interchangeable with a similar series model. Before purchase or replacement, verify:
Siemens identifies 6GK7542-1AX10-0XE0 as a functionally compatible successor. Engineering review is still required before migration because hardware configuration, firmware, topology and project settings may differ.
Siemens Industry Mall lists PM400: Announcement of product phase-out for 6GK7343-1CX10-0XE0, with product phase-out since 01.10.2023. The wording is retained exactly and is not converted to Discontinued.
It identifies the CP 343-1 Lean variant with two RJ45 Industrial Ethernet interfaces for SIMATIC S7-300 communication.
The official data includes TCP/IP, UDP, multicast, SEND/RECEIVE with or without RFC1006, Fetch/Write, S7 communication server functions and PROFINET IO device operation.
Siemens states PM400: Announcement of product phase-out, with phase-out since 01.10.2023. This is not rewritten as Discontinued.
No. The complete hardware configuration, firmware, network topology, addressing and STEP 7 project should be checked before migration.
Verify the full order code, hardware and firmware version, RJ45 ports, label, connector condition and packaging evidence.
Yes. Request clear photographs of the full unit, Siemens nameplate, RJ45 interfaces, power connector and packaging.
Send us the complete part number, required quantity, destination country and product label photos. Our team will check availability, condition, compatibility requirements and shipping options.
Stockoems supports industrial spare-parts purchasing with a practical review process covering order-code identity, installed-system context, visible condition and export handling. For 6GK7343-1CX10-0XE0, buyers can provide label photos, cabinet information and project requirements so our team can organize a clearer compatibility and condition review before dispatch.
A useful procurement check goes beyond matching a short model name. Our team reviews the complete suffix, visible hardware features, connector arrangement and the buyer’s installation notes. The following workplace photographs show three different activities used during this process: reading the unit label, comparing cabinet wiring with technical documentation, and jointly checking module information before commercial confirmation.
| Review Area | Procurement Value |
|---|---|
| Complete Model Identity | Full order codes and suffixes are compared to reduce the risk of receiving a similar but incompatible configuration. |
| Installed-System Context | Hardware, firmware, software, operator-panel and field-connection details can be included in the pre-order review. |
| Visible Condition Evidence | Photos can document the enclosure, label, ports, accessories, packaging and other visible features of an available unit. |
| Clear Order Coordination | Quantity, destination, inspection requests, warranty scope and delivery options are consolidated before shipment. |
| Protective Export Handling | Packing is selected with sensitive industrial electronics and the planned international route in mind. |
Provide the exact part number, quantity, destination and installed-system details.
Labels, connectors, physical condition and requested technical checkpoints are examined.
Availability, inspection scope, warranty and shipping choices are organized for approval.
The unit is prepared for the chosen route with supporting shipment documentation.
For the strongest compatibility review, send clear photographs of the installed nameplate, adjacent connectors and cabinet position together with any available STEP 7 project or maintenance record details.
A varied selection of industrial automation and control models for maintenance, modernization and spare-parts planning.
