It handles point-to-point serial communication using ASCII, 3964 (R), or RK 512 protocols, each with a 1 024 byte buffer. Transmission rate is selectable from 0.3 kbit/s up to 76.8 kbit/s (half-duplex only at the top rate). The module draws 70 mA from the backplane bus and up to 200 mA from the 24 V DC supply, dissipating 4.8 W max. ## Obsolete — sourcing through independent channels Availability is limited to new-old-stock or surplus inventory sourced through independent distribution. ## RS232C interface and protocol support The single isolated RS232C interface supports ASCII, 3964 (R), and RK 512 protocols, each with a 1 024 byte data buffer. The FB length in RAM is 5 500 bytes for data communication send/receive functions. Customer-specific drivers are reloadable, and the module connects via 3 screw terminals (L+, M, GND) for the supply voltage. Maximum cable length is 15 m.","metaTitle":"Siemens 6ES7341-1AH01-0AE0 CP 341, RS232C, Obsolete","metaDescription":"Siemens CP 341 communications processor for S7-300, RS232C interface, 76.8 kbit/s, 1 024 byte buffer.
