Hello, we are starting up  a new Irc5, with the lastest RW (5.14.3), and a Profibus DP-V1 board.
We configured the board as the manual info. All led's are green. Our PLC found the board.
But we can se the any input from PLC, and the PLC can't see any output from the robot.

We changed the PLC, and the same problem. The PLC can comunicate with the other profibus boards.

We checked the configuration in the robot, adreess, type of board, etc.

Any idea?

    hello,

    are you using a siemens PLC?

    in a siemens PLC you cannot read directly the inputs/outputs from profibus robot.

    you have to first copy the PIW and PQW to merkers or datablock and then use these signals to read/write

    and if you use words (16 bits) as integers dont forget to byteswap them. 

     

    hope it will work

    Hello, I'm sorry for delay. I was working on field.
    Finally we found the problem. The customer, gives us a old cpu, that doesn't support dp-v1 only dp-v0.
