"Different connection on K102 pin P and pad COM (none/N$48) it says, it's one among many. K102 is not part neither on the schematic nor on the board, If I try to search for it I find nothing. N$48 is on component K10 so where does K102 come from and how do I fix this?

There's a heap of information /answers to questions you would need to
provide to narrow down how this happened. The fix could well be that you
will need to edit the XML of the sch and brd files.

Your best move is to upload the files so that we can see what has
happened to them.

Zip them if they are to big to post and you may need to zip them
separately and post them in two separate postings.

Alright, I apologize. Here are the board and schematic files.

Hi
Thanks for posting the Sch and Brd files.

I think you have found a bug. I see you are using v8.0.1
If Jorge is reading this, please check the files the OP posted.

I checked out your files using v7.7 and I see K102 as well in the error
list and yet there is no K102 nor in the XML
That K102 appears to be a poorly described gate 2 of K10
There are many example there in the files you posted

As is normally the case with lost forward/backward annotation (Lost
consistency) you likely made changes in the schematic without having the
board open at that time. Always have both open as you perform edits.

One problem is the COM pads of the relays on the board. I feel at one
time the schematic had nets and then they were removed with the board
not open. The pads have contact references on them but that signal goes
nowhere else.

The simplest fix was to connect all the NO pins and that X5-1 pin with
N$97 and then with the board open, delete all the N$97 net connections
and board then dropped the reference to that net on all those pins.
Hence all those errors disappeared.

The other pins all had different nets so to do the job quickly I edited
the XML for the board. They stood out because they were signals with a
single Contact Ref to a COM pad.


Long story short, I have corrected the inconsistencies in your BRD file
so you should be good to go.

You will likely have to pick it up from
http://www.eaglecentral.ca/index.php/f/36/82ebb8ae529a7d06eea5d20bcc1b1ba4/
as E14 cannot pick up attachments from the newsgroup forum that E14
piggy backs onto.

All the best
Warren

Yes there is a fault in the library with different names for the Contact
pads in symbol and device.

Hi Warren,

I hope you're doing well. You are indeed correct this is definitely a
bug and one that has apparently been around for a while. I'll write a
bug report so that this can be resolved.

Thanks for everything you did to help this user out.

Let me know if there's anything I can do for you.

Best Regards,
Jorge Garcia
