Product Details：

Product Dimensions：

The Siemens 6GK1105-2AC10 is a Layer 2 Industrial Ethernet Switch module designed for use within the SIMATIC S5 PLC system, specifically to enable networking capabilities for S5 communication processors. It is part of the OSM (Optical Switch Module) family, though this particular model provides electrical connectivity.

Product Specifications

Product Designation: CP 1430 TF
Full Product Type: SIMATIC NET, CP 1430 TF (Communication Processor for S5, Industrial Ethernet Switch Function)
Function: Communication module with integrated Industrial Ethernet Layer 2 Switch functionality.
Platform Compatibility: Designed to be mounted in the chassis/rack of a SIMATIC S5-115U, S5-135U, or S5-155U PLC.
Communication Ports: Features five electrical RS-45 ports for Industrial Ethernet connections.
Data Rate: Supports 10/100 Mbps transmission rates (Fast Ethernet).
Connection Type: Twisted pair (TP) cable using standard RJ-45 connectors.
Switch Functionality: Layer 2 functionality, enabling the connection of up to four other Industrial Ethernet nodes to the S5 PLC network.
Integration: Allows the S5 PLC to communicate with other devices and networks via standard Industrial Ethernet/TCP/IP protocols.
Supply Voltage: Powered internally by the S5 backplane.

Product Advantages

Enables S5 Networking: The key advantage is allowing the legacy SIMATIC S5 platform to participate in modern Industrial Ethernet networks, protecting existing investments.
Integrated Switch: With five integrated ports, it functions as both a communication processor for the S5 CPU and a small, managed Layer 2 switch, reducing the need for external network components.
Robust Industrial Design: Being a SIMATIC NET component, it is built to withstand harsh industrial environments, offering high electromagnetic compatibility and resistance to vibration and shock.
Diagnostic Capabilities: Provides onboard diagnostic functions and LED indicators for link status, activity, and switch operation, aiding in troubleshooting.
Simplified Migration: This module often serves as an essential bridge device during a phased migration from the S5 platform to the newer SIMATIC S7 or other control systems.

Important Considerations (Precautions)

Legacy Status: The SIMATIC S5 platform is an obsolete/legacy system. While the module is functional, technical support and replacement parts may become limited. Consider long-term migration strategies.
Cabling: Only use approved Industrial Ethernet patch cables (Category 5/5e or higher) with shielded twisted pair (STP) to ensure data integrity and noise immunity in industrial settings.
Network Planning: Due to its Layer 2 functionality, proper network topology (e.g., star or line) and management of MAC addresses are required to prevent network loops and broadcast storms.
IP Configuration: The module's communication settings, including the IP address and subnet mask, must be correctly configured using SIMATIC NET configuration tools to match the existing network infrastructure.
Power Cycling: Ensure the S5 rack is powered off before inserting or removing the CP 1430 TF module to prevent potential damage to the module or the backplane.

Product Applications

The 6GK1105-2AC10 CP 1430 TF module is primarily used in facilities still operating SIMATIC S5 PLCs that require integration into modern, plant-wide communication networks.

S5 System Integration: Allows S5 CPUs to exchange data with SCADA systems, HMI panels, and higher-level control systems (like MES or ERP) via the TCP/IP protocol stack.
Small Control Networks: The integrated 5-port switch enables the S5 PLC to form a small, local network cluster with other nearby controllers or network-enabled devices, such as drives or remote I/O blocks.
Bridging Old and New: It serves as a communication gateway, enabling a structured migration path where older S5-controlled processes need to report data to a central management system running on modern Industrial Ethernet.
Remote Programming and Diagnostics: Provides a network interface for remote configuration, programming, and diagnostic access to the S5 CPU using a standard network connection.
