Techman/Omron cobot ProfiNet problems

    Hello,

    I'm new here, hoping that someone has experience with Techman/Omron cobots.

    I'm trying to communicate with Siemens PLC over ProfiNet using TMFlow. I'm successful with reading the values, but unable to write anything.

    I'm trying like that: Set block -> Variables -> profinet_write_output_bit(518, 0) = 1.

    It runs fine, but it does nothing. I also tried doing it like so: result = profinet_write_output_bit(518, 0, 1) which should be more logical way according to TMscript manual, but it does not accept the input.

    After 9 years of PC and robot programming I'm really struggling with that dumb graphic way of doing it.

    We are arranging a Techman course in the future, but that's the only thing that I need to solve in order to make the application work.

    Thank you very much in advance.

    Best regards,

    Primož

    Approved the thread.

    Hi primoz,

    I think you are writing in a part of the Profinet table that is already in use by the cobot itself, to expose the DO to profinet devices.

    You should write here:

    These registers are "free memory" for you to do what you want.

    Images are from the TMFlow 2.14 software manual, appendix F.

    Hope this helps!
