Nothing. Same text. Multiple response

Need more info here… Whats the model of the panel? If you aren’t in the industry, could you post a picture of the panel? My knowledge with Siemens is pretty limited but I’ll see if I can help get you an answer here.

Multiple Response means you have two devices that have been addressed identically. Presumably they are both the correct type of device for that address, otherwise I believe you would also have an Incorrect Device ID trouble.

Probably too late to help, sorry.
