Properties / services Application The CP 343-1 communications processor is intended for operation in a SIMATIC S7-300, SIMATIC C7-300 automation system or SINUMERIK 840D power line. It allows the connection of the S7-300 to Industrial Ethernet and supports PROFINET IO. To integrate the CP in a linear bus or a ring, to connect a further Ethernet device or to use PROFINET media redundancy, a 2-port ERTEC real-time switch with autocrossing, autonegotiation and autosensing was integrated.
Enhanced functions of earlier firmware versions and predecessor modules You will find an overview of the earlier firmware versions and predecessor modules in the version history of the Industrial Ethernet CPs on the Internet pages of Siemens Automation Customer Support under the following entry ID: 56699406 (http://support.automation.siemens.com/WW/view/en/56699406)
