Now i want to visualize this at a HMI. But i would like to have the devicename instead of the diagnosticadress. Is it possible to get the devicename from the diagnosticadress? I already tried the function _getactivenameofstation but it only works with the simotion adress, not with the adress of the slaves. Regards Sebastian
