Last tip set your node address to something like 77 and you will probably never have to worry about it again as you don’t normally find node addresses that high.

I would venture a guess to say that your PLC-5 in which you are having a problem is configured at I tried to connect with DF-1 but no luck.
The is for unsoldering: Maybe I am misunderstanding what you mean.
