Siemens 6ES7193-6AR00-0AA0 BusAdapter BA 2xRJ45

Product Overview

The Siemens 6ES7193-6AR00-0AA0 is a BusAdapter BA 2xRJ45 for the SIMATIC ET 200SP distributed I/O system. It provides two RJ45 sockets with an integrated 2-port switch, enabling ET 200SP interface modules to connect to PROFINET IO networks. Supporting line and ring (MRP) topologies at 100 Mbit/s, it eliminates the need for external switches and simplifies network cabling in compact control panels.

Compatibility & Applications

Compatible with ET 200SP interface modules IM155-6 PN ST, HF, and HS. Essential for PROFINET line topology, ring redundancy, daisy-chained I/O stations, and compact panel installations where external Ethernet switches are impractical.

FAQ

• Q: What is the difference between BA 2xRJ45 and BA 2xFC? A> BA 2xRJ45 uses standard RJ45 connectors. BA 2xFC (FastConnect) uses Siemens FastConnect technology for faster, tool-free termination. Both support the same network functions.
• Q: Does it support MRP ring redundancy? A> Yes, the integrated 2-port switch supports Media Redundancy Protocol (MRP) for ring topology fault tolerance.
• Q: Can I use this with ET 200SP CPU modules? A> Yes, the BusAdapter connects to any ET 200SP interface module or CPU with BusAdapter support.
• Q: What cable type is recommended? A> Shielded twisted-pair Industrial Ethernet cable (Cat 5e or higher) with RJ45 connectors.

Installation Guide

1. Insert the BusAdapter into the ET 200SP interface module or CPU.
2. Connect PROFINET cable from the controller or upstream device to RJ45 Port 1.
3. Connect downstream ET 200SP station or device to RJ45 Port 2 (for line topology).
4. For ring topology, close the loop at the last station back to the controller MRP port.
5. Verify link LEDs illuminate green on both ports.

Selection Tips

• Use 6ES7193-6AR00-0AA0 for standard RJ45 PROFINET connection in ET 200SP systems.
• For fiber-optic applications, consider BA 2xLC (6ES7193-6AG40-0AA0) or BA 2xSCRJ.
• For FastConnect tool-free wiring, use BA 2xFC (6ES7193-6AF00-0AA0).
• Verify your PROFINET controller supports MRP if ring topology is required.
