Hi,
I fell into a trap the other day.
I had a comfort II system that had an Ethernet UCM which was addressed at ID 1. (it was being used by a third party device)
I then connected my serial UCM to do some programming. I didn't know this at the time but it was also addressed at ID 1. The system or software didn't complain that there was a problem but after the download was complete, weird things started to happen. like..... only the outputs on the main board would work and the inputs only worked sometimes. Everything else on the panel seemed fine though.
Needless to say this drove me crazy for about 6 hours trying workout what was wrong. I even replaced the main panel and LEM with no results.
it turns out that 2 UCM's at ID 1 = weird problems!
I know comfort ignores devices at ID 1, but is there any way for comfigurator to show a warning if there are 2 or more UCM's at ID1 before a download?
It could save other people making the same stupid mistake that I did! 
Regards,
Scott

When you have 2 UCMs sharing the same ID, they both will respond to the poll by Comfort. In most cases when nothing is happening, the response from the UCMs would be the same, so you (or Comfort) would not even know about it. Hence it would not be possible to show a warning before an upload/download
When you are downloading using one UCM, it will start to get interesting, but because Comfigurator and the UCM retries when it does not get a good reply from Comfort, the situation may not be noticed and the download may complete

Yea, the download went in every time without an issue. The panel just acted weird when i did this with the 2 UCM's at ID 1. Interesting!
