The Siemens CP340 communications processor (model 6ES73401AH020AE0) for SIMATIC S7-300 adds an RS232C (V.24) serial interface to the rack-based PLC system. Designed for the S7300 family, the CP340 plugs into a SIMATIC S7-300 backplane and provides an RS232-C interface for serial data exchange with other equipment. This module ships with a configuration package on CD to simplify setup and parameter configuration. Typical use cases include establishing a serial link for data exchange and remote configuration between the S7-300 and external devices within a Siemens automation installation.
