Features:
- Two switched RJ45 ports place the S7-300 station on a 10/100 Mbit/s Industrial Ethernet segment.
- S7 communication, TCP/IP, ISO-on-TCP, UDP, and multicast services share the module communication resources.
- PROFINET IO device operation lets the station exchange cyclic data under an external IO controller.
Siemens 6GK7343-1CX10-0XE0 adds Industrial Ethernet communication to an S7-300 or C7-300 rack.
The CP exchanges data with the CPU through the backplane and sends it over the Ethernet ports according to the configured service.
Its diagnostics pages and management protocols provide link, time, and redundancy information during commissioning.
The Siemens 6GK7343-1CX10-0XE0 CP 343-1 Lean Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
Switched Ethernet Connection
- Port arrangement: Two RJ45 sockets connect through one integrated switch.
- Line rate: Each port negotiates 10 or 100 Mbit/s operation.
- Network path: The switch can continue an Ethernet segment through the rack station.
- Backplane role: Controller data enters the CP through the S7-300 backplane.
PROFINET IO Device Operation
- Configured role: The CP operates as a PROFINET IO Device rather than an IO Controller.
- Cyclic exchange: An external IO controller reads and writes the assigned process data.
- Addressing: The device name and IP parameters identify the station on Ethernet.
- Engineering: STEP 7 assigns the communication services and PROFINET data areas.
Communication Resource Limits
- Open services: Up to eight open communication connections share the CP resources.
- S7 channels: S7 server connections operate alongside configured open communication.
- Message length: TCP and ISO jobs allow more user data than UDP datagrams.
- Selection check: Connection counts and message sizes must be checked together before configuration.
Network Diagnosis and Recovery
- Web pages: The integrated server reports module and connection state.
- Management: SNMP and LLDP expose port and neighbor information.
- Ring operation: MRP supports a configured Ethernet ring recovery path.
- Time service: NTP synchronizes the CP clock with a network time source.
