The LEAN variant lacks the Advanced's additional features like PROFINET IO controller capability and integrated two-port switch. If the application only needs basic TCP/IP connectivity for an S7-300, the LEAN was the cost-optimized choice; the Advanced adds functionality but also a different order code and firmware baseline.","metaTitle":"Siemens 6ES7343-1CX10-0XE0 CP 343-1 LEAN, EOL","metaDescription":"Siemens 6ES7343-1CX10-0XE0 CP 343-1 LEAN communication processor for S7-300.
