Transmission rate is configurable from 0.3 kbit/s up to 115.2 kbit/s across all three protocols, matching the maximum supported by the RS422/485 physical layer. ## Power draw and environmental limits The CP 341 draws up to 70 mA from the 5 V DC backplane bus and up to 100 mA from the 24 V DC supply (L+), with a maximum power loss of 2.4 W and typical loss of 1.6 W. The 15-pin sub-D socket connector mates with standard RS422/485 cabling; maximum cable length is 1 200 m at the lower baud rates. ## Sourcing an end-of-life S7-300 serial module For a like-for-like replacement within the S7-300 family, confirm the protocol and buffer requirements against the current CP 341 variant list; for a platform migration to S7-1500, the 6ES7511-1AL03-0AB0 CPU with its integrated PtP capability is a functional path, though it requires a different rack and engineering environment.","metaTitle":"Siemens 6ES7341-1CH02-0AE0 CP 341, RS422/485, 115.2 kbit/s","metaDescription":"Siemens SIMATIC S7-300 CP 341 communications processor with isolated RS422/485 interface.
