Good day!

I am unable to get a result with this communication, I tried the 2 forms and nothing happens, always the INTF LED lights.

I'm trying with 2 CPU 414-2DP.

Could assist me in any way.

Thanks.

 Hello ,

What type of communication did you plan over PROFIBUS network? Please share the hardware configuration of both CPUs and section of your program related to communication.Normally, diagnostic buffer of CPU provides helpful clues . For master-slave communication (or other types) over PROFIBUS , There are also feedback on returning values of functions,checking them with online manual will help you to figure out the error.

I hope that helps,
