CP 343-1 Lean / SIPLUS 343-1 Lean
The CP 343-1 Lean and the SIPLUS 343-1 Lean are designed for connection of a SIMATIC
S7-300 system to Industrial Ethernet
networks also as a PROFINET IO device.
The device has the following characteristics and functions:
● A PROFINET interface with two RJ-45 connectors,
● 10/100 Mbps, full / half duplex with the functionality for autosensing and autocrossover
via an integrated 2-port switch
● Media redundancy (MRP):
– In an Ethernet network with ring topology, the communication processor supports the
media redundancy protocol MRP
