Live wire from Module 4,10,03 Block 4250 (FC 80) does not connect to anything - 
(3380,2340) (3380,2260) (3560,2260) on 41003H1D.CAD

Sometimes, a line is left attached to a source that is no longer used. Deleting the line will eliminate the message. Also this message could be saying that a signal has no connection at the coordinates shown. This message means that a signal was processed that did not end up being fed anywhere.

It could mean that a signal has no connection at the coordinates shown, but there are number of possible cosmetic causes as well:

1. A common cause is that an IREF is used to bring a visual line from an external diagram to what looks like an input on an AI: Analog Input [FC27] or DI: TCS Digital Input [FC43] block. There is actually no input for these blocks, so the message may be ignored in these cases.
2. Sometimes, a line is left attached to a source that is no longer used. Deleting the line will eliminate the message.
3. They may tell you that a signal is brought out from the named IREFs but not used. This shows up if people delete logic without deleting the IREFs that feed it.

In this example, the wire from (3380,2340) to (3380,2260) does not connect with the wire from (3380,2260) to (3560,2260):
