The Siemens 6ES7193-6AG40-0AA0 is the SIMATIC ET 200SP BA LC/FC PROFINET Bus Adapter. It belongs to the ET 200SP Bus Adapters family and combines one LC glass-fiber interface with one Fast Connect copper interface. The adapter provides one PROFINET interface and is designed as a media-conversion solution for connecting optical and copper network segments. Siemens documentation specifies one LC port and one Fast Connect connection, with copper cable lengths up to 100 m and multimode graded-index fiber lengths up to 3 km for both 50/125 µm and 62.5/125 µm fiber. The adapter is intended for compatible ET 200SP PROFINET devices and is particularly relevant where a direct Fast Connect bus-cable connection is preferred instead of a conventional RJ45 plug. Siemens documentation lists a 20 × 69.5 × 59 mm form factor.

6. Important Ordering & Installation Information

• Order the exact article number 6ES7193-6AG40-0AA0.
• This is the BA LC/FC variant, not BA LC/RJ45.
• Verify that the target ET 200SP PROFINET device supports the Bus Adapter.
• Use compatible multimode glass-fiber cable for the LC interface.
• Use appropriate PROFINET copper cable and Fast Connect termination for the FC interface.
• Observe the documented 100 m copper and 3 km multimode-fiber limits.
• Verify the applicable Siemens manual revision for the environmental limits of the installed hardware version.
• The Bus Adapter is mounted to the compatible PROFINET device before network cabling is connected.  

Always follow the manufacturer's official installation, wiring, commissioning and safety instructions.

7. Why Choose Siemens 6ES7193-6AG40-0AA0?

The Siemens 6ES7193-6AG40-0AA0 is a suitable choice for ET 200SP installations requiring LC multimode fiber and Fast Connect copper connectivity. Its 3 km optical capability, 100 m copper specification and ET 200SP Bus Adapter compatibility provide a defined solution for mixed-media PROFINET architectures. The Fast Connect interface is particularly useful where direct industrial bus-cable termination is required.

8. Product Summary
