Siemens CP 341 6ES7341-1CH02-0AE0 is a SIMATIC S7-300 communications processor that provides a dedicated RS-422/RS-485 serial interface for PLC-to-device communications. It is powered from 24 V DC and draws up to 100 mA from the supply (L+) and up to 70 mA from the backplane’s 5 V DC rail, and it offers a single RS-422/RS-485 interface with a maximum transmission rate of 115.2 kbit/s (X.27). The module ships with a configuration package on CD. In S7-300 configurations, it functions as a plug-in communications processor to connect the PLC to RS-422/RS-485 networks and peripherals.
