Product Description

The 6GK7343-1EX30-0XE0 is a CP 343-1 Communications Processor for the SIMATIC S7-300 PLC system. It is designed to connect the S7-300 controller to Industrial Ethernet networks. This module is essential for modernizing S7-300 systems, enabling high-speed data exchange, integration with IT systems, and supporting PROFINET IO controller or device functions.

Product Parameters

Key Product Advantages

• Integrated Switch: The dual RJ45 ports act as a 2-port switch, allowing for cost-effective “daisy-chain” line topologies without needing external network switches.

• Multi-Protocol Support: It handles diverse communication tasks simultaneously, from standard S7 communication to open TCP/IP protocols for third-party device integration.

• Remote Maintenance: Built-in web server capabilities allow for remote diagnostics using a standard web browser, significantly reducing troubleshooting time.

• Media Redundancy (MRP): Supports the MRP protocol, ensuring high network availability; if a cable breaks in a ring topology, communication is rerouted instantly.

Critical Usage Notes & Precautions

1. IP Address Configuration: The IP address can be assigned via STEP 7 / TIA Portal or via the “Primary Setup Tool” (PST). Ensure there are no IP conflicts on the plant network before connecting.

2. External 24V Supply: Unlike some I/O modules, the CP 343-1 requires an external 24V DC power supply connected to the front terminal for the Ethernet interface to function.

3. Firmware Version: To use advanced features like PROFINET IO, ensure your STEP 7 hardware configuration matches the firmware version printed on the side of the module.

4. Cabling: Use shielded Cat5e (or higher) Industrial Ethernet cables. Ensure the shield is properly grounded at the connector to prevent electromagnetic interference.

Product Applications

The CP 343-1 is the primary gateway for networking S7-300 systems:

• Plant-wide Networking: Connecting multiple S7-300 and S7-400 PLCs together for data synchronization across a large factory.

• HMI/SCADA Integration: Linking the PLC to WinCC, TIA Portal, or third-party SCADA systems over Ethernet.

• PROFINET Networks: Acting as a PROFINET IO Controller to manage remote I/O stations (like ET 200S or ET 200SP).

• IT/Enterprise Integration: Sending production data via E-mail or TCP/IP to upper-level ERP or MES systems.
