Thank you for all of your help Peter, I have finished all of my testing now the conclusion is clear.

OK if you have +24V on TB1 pin 5 relative to TB1 pin 8
and no red LED above TB1 when LinuxCNC is not running,
The 7I76EUs field I/O section has failed or been damaged.

23.9v
Thanks

If you measure from
TB1 pin 8 (-) to TB1 PIN 5 (+)
 What do voltage do you get?

 

W1 is in the default position left and the fileld power is correctly conneced
Thanks
George

OK that means you have no VIN so the field I/O section is unpowered

Normally VIN comes from VFIELD (W1 LEFT)

So either you have:

1.  No VFIELD

2. W1 is in the right hand position (it should be in the default left position)

3. Some hardware issue with the field I/O section.

no it never lights,
thanks

Before you start LinuxCNC, does red LED CR11 (above TB4) Illuminate?
 

Hi PCW,
I have attached the linuxcnc report. I put it for line 36 in hal but all of the other inputs 05-09 were the same errors. No there aren't any red led's on the board at that location with the error i get there will be one in amonst the boot up led's.
Thanks

When you say you have an error,
Please please copy/paste that error
in your post.

It's nearly impossible to diagnose the issue
without accurate error reporting.

Also do you have a red LED (CR11) illuminated
above the Spindle connection (TB4) ?

 

I just figured out what the gpio pins are and they are if iam correct the 50 pins on P1 and P2 halshow was not showig any sserial port pins. That is probably why the pin do not exist errors I was getting is from.
Just a thought

Thank you for your response PCW. I have checked and there is field power of 24v across pins 1&8 it is also tranfered to the nearby power block can't remember its tb number but done as mentioned in posts and manuals.
Thanks

The field I/O (TB4,5,6) is not GPIO.

If you assign TB5 or TB6 I/O pins or spindle (TB4) pins in pncconf and
you get pin not found errors, this most likely means that you do not
have field power applied (TB1 = ORANGE  connector)

forgot to mention that in halshow i could not see any action on pins the only ones i could see were gpio pins and it listed 50 pins. Just for curiosity i looked at all 50 of the pins and tried activating the limit switchs and saw no change

Startiing on line 34 of hal limits not existing pin does not exist. I commented out all six lines after reltating to non existing pins to get thru with no errors. I checked these pins on TB6 04-09 and they all has voltage of 24v until activated then went to aprox .4v.There may be an issue with the board.
Thanks PCW
