    DP/DP Coupler

    Platform, Opcon modulo(VPB40+VDP40)

    Field bus: Profibus

    I am using DP/DP coupler in my project to realize the communication between two stations. I am facing an issue that a bit in DP/DP coupler communication is abnormal.

    As it shows in the captures, QX350.0 is off from staion 010, however at the same time IX350.0 is on in stat020.

    Other bits seems identical between two stations.
