Hi, 

I have to implement profibus DP communication to an Atlas Copco MK5 interface module. I found very little information about the module itself. 

Anyone have experience with the module?

Do you know where to get a detailed description of the GSD file? 

Is there an example somewhere I could use?

Hello,

maybe this Daniel's link can be helpful for start:

Hi, 

After a while I am working on this task again. I created a small FB to handle the communication, but it does not seem to work. The Syncbits comes back as they suppose to be. IT seem like the communication is live and it is working fine, but for whatever reason the values in Bytes 4,5,6,7 always the same. No matter what request I send down to the MK5 unit the value in Bytes 4,5,6,7 i the same. 

See the attachments.

Hello, could you share the FB backup?

I'm having trouble reading this data. 


Thank you.

Have you solved this problem? I have the same issue
