- Description
The Siemens CP 343-1 Lean (6GK7343-1CX10-0XE0) is a communications processor that connects a SIMATIC S7-300 CPU to Industrial Ethernet via TCP/IP and UDP, with an integrated 2-port ERTEC 200 switch and PROFINET IO device support. It handles S7 communication as a server, SEND/RECEIVE with RFC1006, and fetch/write over two RJ45 ports at 10...100 Mbit/s, drawing 24 V DC at 0.16 A typical.

Selection Notes
As a spare-part Lean variant, this CP covers PROFINET IO device operation with S7 communication and open communication over 8 SEND/RECEIVE connections - a lighter connection budget than the CP 343-1 Advanced, which adds a PROFINET IO controller role and a Gigabit uplink. Pick the Lean version when the S7-300 station only needs to report into a higher-level PROFINET/Ethernet network as a device, not act as a controller for its own IO devices.
Applications
Adds PROFINET IO device and Industrial Ethernet connectivity to S7-300 stations exchanging data with SCADA, MES, or other S7 controllers over TCP/IP, UDP, or S7 communication.
