Features:
- Industrial Ethernet communication includes ISO, TCP, ISO-on-TCP, UDP, and multicast.
- PROFINET IO controller operation supports up to 125 configured IO devices.
- FTP, HTTP, email, SNMP, DHCP, and NTP extend the processor beyond cyclic control traffic.
Siemens 6GK7343-1GX21-0XE0 gives an S7-300 station a CP 343-1 Advanced connection to Industrial Ethernet.
The connection resources of 6GK7343-1GX21-0XE0 are shared across open communication, S7 traffic, PROFINET, and IT services.
Flash and RAM file areas allow 6GK7343-1GX21-0XE0 to serve or transfer stored content while the controller exchanges process data.
The Siemens 6GK7343-1GX21-0XE0 CP 343-1 Advanced Industrial Ethernet 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.
Open Ethernet Communication
- ISO transport: ISO communication carries configured data directly over the Industrial Ethernet service.
- TCP transport: TCP provides a connection-oriented IP path for larger user-data blocks.
- ISO-on-TCP: ISO-on-TCP adds the ISO transport service above TCP/IP for partners configured for that protocol.
- UDP transport: UDP sends shorter datagrams without the connection handling used by TCP.
- Multicast: A configured sender can address multiple multicast stations without creating a separate unicast path for every partner.
PROFINET Controller Operation
- Controller role: 6GK7343-1GX21-0XE0 exchanges cyclic input and output data as the PROFINET IO controller.
- Device count: That controller configuration can include up to 125 PROFINET IO devices.
- Process-data areas: The input and output directions each provide up to 4 KiB for the controller exchange.
- Diagnostic path: PROFINET diagnostics distinguish link, device, and configuration faults from errors in the CPU program.
Stored Content and Network Services
- FTP client: The CP initiates configured transfers from its file area to an Ethernet file server.
- FTP server: Remote clients use the separate server connections to access permitted files on the processor.
- HTTP service: The integrated HTTP connections serve stored web content to configured browser clients.
- Email service: The email client sends configured messages through the Ethernet network.
- Network support: NTP supplies time synchronization while DHCP can provide the configured IP addressing arrangement.
S7-300 Installation Resources
- Backplane supply: The S7-300 rack supplies 5 V DC to the internal module electronics.
- External supply: A separate 24 V DC feed powers the communication processor through its external supply connection.
- Shared dependency: 6GK7343-1GX21-0XE0 needs both the rack interface and the external feed before its Ethernet services can operate.
- Thermal planning: The documented 14.7 W power loss becomes cabinet heat, so mounting orientation and enclosure temperature must be evaluated together.
