Hi All,

I currently have an IM151-1 Standard (6ES7151-1AA06-0AB0) interface module connected to a DeltaV controller via profibus connection. However, the SF and BF indicators are constantly flashing on the IM151-1 module.

I have tried several ways to troubleshoot this issue, as listed below.

• Downloaded the latest gsd file (v4.0) from the Siemens website and imported that into the DeltaV software. 
• Confirmed that the address in the software configuration and physically on the dip switch are set to 3.  
• Replaced the IM151-1 interface module, the profibus cable, and the DeltaV profibus card.  
• Downloaded the DeltaV controller several times.
• Termination was also checked.

Any other suggestions for resolving this issue would be appreciated.

Thanks!
