Hi Andy

I appreciate your replies. Since posting I have fixed the labels to all S, or 
D, not other oddities. Based on the documentation this scheme should link in 
the wire number within the label.

I did locate and correct the 7 segment LED pins (I did have input/output, now 
all passive). I was trying various permutations on the sheet pins and have had 
no luck with any of that.

And as you suggested, I looked into the schematic and the net list. There is 
definitely no connection in existence between the unconnected pins and any 
net identifier.

I am at a complete loss to understand this and am thinking I might be advised 
to try the developers for some insight to the issue.

kind regards

Greg

 I don't normally use multiple sheets with connecting labels, so I might

  e.g. on the 7 segment devices you have S0,S1,S2,
 LED3...and so on, connected to an LED label 
 
 You drivers have labels such  as D0-D14 and S0-S16 so there seems to be a
 bit of a mismatch.
 
 Also the segment drive connection on the top sheet seems to be an INPUT to
 sheet Eng uP serial Signal, and that connects to another series of buses
 LED, Bar_Gr and so on which are also shown as INPUTS
 
 
 In contrast the Display select is shown as an OUTPUT connecting to an
 INPUT.
 
 
 I would have thought that an input should connect to an output and so on.
 again I dont use this form of connection myself so I could be wrong.
 
 On other BAR_Gr sheets, the symbol is different again.
 Cool Temp, Oil Press are different from the other BAR_Gr pages, likewise
 things like Tach0 have yet another type of connector symbol.
 
 
 This does not seem quite right to me.

Hi Andy,

Thanks for the advice. I am using the native symbols in the problem schematic.

Perhaps if I post the pdf print up it will make more sense.

Something else popped up since my post. Invisible pins (from the same Library 
Item) are also reporting the same error, but they change each re-run of the ERC 
rules check.

Look in files for the copy.

regards

Greg

 Sometimes when importing from other sources things can go a  bit haywire
 and duplicate pins can get created.
 
 Check the lib files very carefully, as it has been known for pins to get
 duplicated in the lib. (you will not see this in the graphical editor, as
 everything will be on top of each other, you need to look at the lib file
 itself) It's a text file, and with the number of errors that you are
 getting, if this is the problem it will be pretty obvious!
 
 Have a look at kipy, a set of python tools that can do some extra
 checking and it will pick up the duplicate pin entry issue it it exists.

  Hi
  
  I am working on a complex schematic where I use a bus between them.
  
  I have common schematics that I developed separately in a folder
  hierarchy then added them to a master diagram for a specific purpose.
  
  I am using 74HC595 Serial-Parallel latches and they interface via a pair
  of R8 packs for 17 of the wires and directly to 15 wires (display
  matrix), and I get this message on 172 occasions:
  ErrType(2): Pin not connected (and no connect symbol found on this pin)
   @ (4.4000 ,3.2500 ): Cmp D90, Pin 1 (passive) Unconnected
  
  ErrType(2): Pin not connected (and no connect symbol found on this pin)
   @ (5.1500 ,4.6500 ): Cmp AFF4, Pin 5 (input) Unconnected
  
  I am driving the LEDs or 7 seg displays from the latches and I am not
  sure if the problem is the interconnecton or something else. There are
  wires, labels etc all applied to the buses and individual wires, but
  there is still no luck resolving this issue.
  
  Can anyone help me with this?
