More Information

Overview Manuals Ethernet Data Services Web & Email Diagnostics

Features:

  • Connects SIMATIC S7-300 controller data to 10/100 Mbit/s Industrial Ethernet.
  • Carries ISO transport, TCP/IP, S7, SEND/RECEIVE, and Fetch/Write services.
  • Adds configured multicast, email, web, LAN initialization, and diagnostic functions.
Siemens 6GK7343-1GX11-0XE0 provides the Ethernet communications path for an S7-300 station.

Configured transport and application services on 6GK7343-1GX11-0XE0 determine which controller data crosses the network.

The diagnostic and web functions of 6GK7343-1GX11-0XE0 remain tied to its STEP 7 hardware and network configuration.

Verify the complete Siemens 6GK7343-1GX11-0XE0 CP 343-1 IT Communication Processor article number and documented interface before matching the installed unit.
Siemens 6GK7343-1GX11-0XE0 CP 343-1 IT Communication Processor Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Network Transport and Station Role

  • Link rate: The processor negotiates the documented 10 or 100 Mbit/s Ethernet rate.
  • ISO transport: Configured ISO connections move controller data using the assigned transport resources.
  • TCP/IP: IP addressing, subnet data, and connection parameters must match the plant network.
  • Station role: The CP hardware configuration binds the Ethernet services to the S7-300 rack.

Controller and Application Exchanges

  • S7 communication: The processor carries configured S7 connections between automation stations.
  • SEND/RECEIVE: Application blocks transfer defined data areas through established connections.
  • Fetch/Write: Remote access uses the configured data blocks and connection permissions.
  • Multicast: One configured transmission can address the intended multicast receiver group.

Integrated Information Functions

  • Email: Configured messages leave through the processor network path and assigned mail settings.
  • Web pages: The integrated web function serves the pages loaded for the CP.
  • LAN setup: Initial network parameters can be assigned through the documented LAN procedure.
  • Separation: Information services do not replace the controller data connections defined in STEP 7.

Commissioning and Fault Isolation

  • Hardware match: The rack slot and exact CP article number must match the offline project.
  • Network check: IP, subnet, gateway, and physical link are verified before connection testing.
  • Connection state: Diagnostic entries separate inactive application connections from a lost Ethernet link.
  • Service test: S7, SEND/RECEIVE, web, and email paths are checked independently.
Description
Siemens 6GK7343-1GX11-0XE0 is a SIMATIC S7-300 CP 343-1 IT communications processor that places the controller on Industrial Ethernet. It transfers controller data through ISO transport, TCP/IP, and S7 communication instead of consuming local signal channels.

Application exchanges through 6GK7343-1GX11-0XE0 use SEND/RECEIVE and Fetch/Write services, with or without RFC operation as configured. Multicast support lets one transmission reach configured recipients while the processor keeps the PLC program path separate from the network service.

Integrated email and web functions on 6GK7343-1GX11-0XE0 expose configured messages and pages through the Ethernet connection. LAN initialization and the diagnostic extensions must match the STEP 7 project before the processor enters the intended station role.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does 6GK7343-1GX11-0XE0 show Ethernet link but no S7 data exchange?
Check the 6GK7343-1GX11-0XE0 rack slot, IP configuration, partner address, connection resources, downloaded hardware configuration, and PLC communication blocks.
Why can the web page of 6GK7343-1GX11-0XE0 open while SEND/RECEIVE remains inactive?
The 6GK7343-1GX11-0XE0 web service and application connections use separate configurations; inspect the SEND/RECEIVE blocks, connection ID, status words, and partner.
What causes duplicate-address faults after replacing 6GK7343-1GX11-0XE0?
Disconnect the replacement 6GK7343-1GX11-0XE0, verify its assigned IP and MAC-based initialization, then remove any device still using the same address.
Why does email fail on 6GK7343-1GX11-0XE0 although controller communication works?
Verify the 6GK7343-1GX11-0XE0 mail server address, routing, message trigger, configured sender data, and network reachability independently of S7 communication.
What should be recorded before changing 6GK7343-1GX11-0XE0?
Record the 6GK7343-1GX11-0XE0 article number, firmware, rack slot, network parameters, connection table, loaded web data, and STEP 7 project archive.
