Description
Additional information

The Siemens 6AV6470-1XA00 is the SIMATIC PC Adapter USB, a communication adapter belonging to the SIMATIC HMI accessory product line from Siemens. It serves as an interface converter that connects a PC or programming device to SIMATIC S7 PLCs and HMI devices via the MPI or PROFIBUS DP bus systems, using a standard USB port on the PC side. This adapter is designed to replace the older serial PC Adapter and eliminates the need for a dedicated serial COM port on modern computers.

The 6AV6470-1XA00 supports MPI and PROFIBUS DP protocols, enabling communication speeds of up to 12 Mbit/s on the PROFIBUS side. It is powered directly through the USB interface, requiring no external power supply, and is compatible with USB 1.1 and USB 2.0 ports. The adapter is recognized by the PC as a virtual COM port via a driver installation, making it compatible with STEP 7, WinCC, and other SIMATIC software tools. The compact housing is robust and suitable for workshop and field use.

The SIMATIC PC Adapter USB is widely used in manufacturing plants, process automation facilities, and machine building environments wherever SIMATIC S7-200, S7-300, S7-400, or compatible HMI panels need to be programmed, configured, or diagnosed from a standard laptop or PC. It is particularly valuable during commissioning, maintenance, and troubleshooting tasks where a direct PLC or HMI connection is required without the use of a dedicated CP communication card.

Common Error Codes & System Events

No COM Port Assigned: The USB driver has not correctly installed a virtual COM port, preventing SIMATIC software from detecting the adapter.
Reinstall the PC Adapter USB driver from the SIMATIC software installation media or Siemens support portal. Check Device Manager for driver conflicts.
Bus Fault / No Communication: The adapter cannot establish communication with the connected MPI or PROFIBUS network.
Verify the correct bus address and baud rate settings in the SIMATIC software. Check the 9-pin Sub-D cable connection and ensure the PLC or HMI is powered and online.
Timeout Error: Communication attempts time out, indicating the adapter cannot reach the target device within the expected response window.
Check that the MPI or PROFIBUS baud rate configured in the software matches the network baud rate. Ensure cable length and termination resistors are correct.
Driver Not Found: Windows does not recognize the adapter after USB connection, and no driver is loaded.
Install the correct SIMATIC PC Adapter USB driver for the Windows version in use. Ensure the driver version is compatible with the installed STEP 7 or WinCC version.
Access Denied / Port Busy: The virtual COM port assigned to the adapter is already in use by another application or process.
Close any other SIMATIC or third-party applications that may have opened the COM port. If necessary, reassign the COM port number in Device Manager.
Firmware Update Required: The adapter firmware is outdated and incompatible with the current SIMATIC software version.
Use the PC Adapter USB firmware update tool available from Siemens to update the adapter firmware to the latest version compatible with the installed software.

Frequently Asked Questions

Which PLC families are compatible with the 6AV6470-1XA00?

The SIMATIC PC Adapter USB is compatible with SIMATIC S7-200, S7-300, and S7-400 PLCs, as well as compatible SIMATIC HMI panels that use MPI or PROFIBUS DP interfaces.

Does the 6AV6470-1XA00 require an external power supply?

No, the adapter is powered entirely through the USB port of the connected PC or laptop, requiring no external power supply.

Which SIMATIC software packages support this adapter?

The adapter is supported by STEP 7 (v5.x), WinCC, SIMATIC ProTool, and other Siemens engineering tools that use a virtual COM port or SIMATIC communication layer for MPI/PROFIBUS access.

Is the adapter compatible with Windows 10 and Windows 11?

Compatibility depends on the driver version. Siemens has released updated drivers for Windows 10; users should verify the latest driver availability on the Siemens support portal for Windows 11 compatibility.

What is the maximum PROFIBUS baud rate supported?

The 6AV6470-1XA00 supports PROFIBUS DP communication at baud rates up to 12 Mbit/s.

Troubleshooting

Adapter is connected via USB but is not recognized by Windows

Open Device Manager and check for unknown devices or driver errors under the Ports (COM & LPT) or Universal Serial Bus controllers sections.

Install or reinstall the SIMATIC PC Adapter USB driver from the Siemens support portal or STEP 7 installation media. Ensure the driver version matches the Windows OS version in use.

STEP 7 or WinCC cannot connect to the PLC through the adapter

Verify the PG/PC interface settings in SIMATIC software. Confirm the correct adapter and access point are selected, and that the MPI or PROFIBUS baud rate matches the network configuration.

Set the correct PG/PC interface to 'PC Adapter (MPI)' or 'PC Adapter (PROFIBUS)' as appropriate. Match the baud rate to the existing network and ensure the Sub-D cable is firmly connected to the PLC's MPI/DP port.

Intermittent communication dropouts during online sessions

Check the USB cable quality and length. Inspect the PROFIBUS/MPI cable for damage, improper termination, or excessive length.

Use a short, high-quality USB cable directly connected to the PC (avoid USB hubs). Verify that bus termination resistors are correctly placed at both ends of the MPI or PROFIBUS segment.

Virtual COM port number conflicts with other devices

In Device Manager, check if the assigned COM port number is outside the range accepted by the SIMATIC software (typically COM1-COM8).

Right-click the adapter in Device Manager, select Properties, go to Port Settings > Advanced, and reassign the COM port to a number within the supported range (e.g., COM3 or COM4).

Adapter firmware is reported as incompatible after a STEP 7 software update

The SIMATIC software version may require a newer firmware version on the adapter than what is currently installed.

Download and run the PC Adapter USB firmware update utility from the Siemens Industry Online Support portal to update the adapter firmware to the version required by the installed STEP 7 release.
