Hi,

I am trying to set/reset digital output by RTDE command from PC in remote mode.  
I can do after brake released but digital output wasn’ changed (always off) before brake released.

Does anyone know the reason why?

I can set/reset digital outpu on teach pendant I/O tab even before brake released.

thanks,  
Hiro
