If I do this, however, it seems that the emergency button, which is Safety, no longer works .... the display always works ... so I tried to change the address on the Box and I put the safety address 1 for trolley 1 , for trolley 2 address 2 and so on up to 10 ... when I connect the mobil panel to trolley 1, I have to go to "control panel" -----> "PROFIsave operation" and put the address 1 ..... when I connect 2 I do the same thing .... in this way the safety emergency button of the panel works .... how do I make sure that the panel connects automatically to make it work also the emergency buttom?
