Delta V profibus interface to Atlas Copco

Hi,

We are running Delta V 13.3 and need to interface with an Atlas Copco MK5 gateway via profibus.

The supplied GSD files seem to be lacking in detail.  We also have a profibus mapping spreadsheet but the defined fields are not available in Delta V.

Has anyone in the community had experience of interfacing Delta V to an Atlas Copco MK5 Gateway via profibus?

If you could share examples of GSD files and or Delta V configuration (FHX export)  it would be much appreciated.

  • David,
    You need the Atlas Copco document "9845 0187 04 Elektronikon MkV Gateway".

    I have interfaced a MkIV and do not know if the MkV is similar, but could share some tips from the MkIV. The GSD appears in Device Definitions as "General / AtlasCopco / Profi2Can" with 16 bytes in and 16 bytes out. It's a request/reply mechanism using the 16 byte buffer so we used a sequence to send a series of requests for different data. There is an Atlas Copco document "9820 3582 03 User Guide MkIV Profibus Edition 06". Please let me know if you think this helps and I can post more details.

    Hi Rob,

    Thanks for your reply.

    Once the GSD is imported I see it here:

    General \ Atlas Copco\ MKV Gateway \ with 16 bytes in and 16 bytes out, that’s after adding definition 2DR.gsd.

    Atlas have also supplied 1DR.gsd, 4DR.gsd & 8DR.gsd.

    In addition Atlas have supplied a gateway profibus map, this is expressed in terms of register address and data words ie:

     

    The connection I’m failing to make is DV expresses itself in terms of Standard network byte order, Data Type and Byte Offset.

     

    If you could share a couple of screen shots of your sequence or the fhx file that would be fantastic. Also, can you please attach the PDF's of the mentioned manuals, I can't seem to find them in Atlas Copco website?

    David,

    The MkIV Profibus manual attached. You will see (page 8) the idea is you have a Profibus buffer, for example 16 bytes is big enough for transferring 2 registers. To read a value you load up the output register with a sequential message number, a command (e.g. read = 001), number of parameters, compressor CAN address and parameter to read. The input buffer then contains the response and you can match up the message number to make sure its what you were looking for.  

    I set up the registers and played around manually entering values to get a feel for it and see the responses coming back. i then put this into a sequence to read one value at a time like temperature then pressure then power in a looping SFC. Each value takes a couple of seconds so the whole read cycle about 10 seconds. In the sequence I made one step to put all the data into the output buffer. Its transition waits for a second and then checks if the input has the same message number and parameter before pushing it out to be used/displayed. I am sure after getting it working manual you will see how the sequence works.

    This is all for the MkIV and it was just by luck i got the manual. Maybe your local Atlas Copco rep and get it for you. I see the MkV manual is posted in scribd.com.

    I hope this helps get you started but please post again with questions or results.

    Hi Rob,

    Thanks for taking the time do to this and the info.

    As yet we do not have a MK5 gateway so have no way of testing.

    As you say some trial and error maybe required once we get the MK5.

    I'll let you know how we go once we get it working,

    Thanks again.

    David

    I just found the MkV manual in a project folder. Good luck.

  • Hello David, We have the same issue and i wonder if you have found a solution? and do you have information about the configuration.

    Who could send me a working application
