Dig IOs visible on HAL (shows Set and Reset by M64,M65) but no physical change

Hallo
I am working with 7i76e and 7i85s. For Testpurposes i only use one axis in closed loop mode. It runs very well.
Closed Loop is very satisviing.

The Hal based definition of IOs works internally very fine. In HAL i obeye the outputs adressed by their GPIO Pin.
As used in cnc program by M64 and M65 they switch on and off as expected.

But here starts the Problem. Measuring with Digital Multimeter in DC Volt range the Outputs Show absolutely no Change.

For Power supply i am working with TB1 Field power Pin 8 GND , Pin 5 24V and TB3 Power Pin 23 GND, Pin 22 24V

Defining of Limit switches in Hal is in my opinoun correct. When i start my cnc prog i receive at once an errormessage caused by
the limit switch which does not gets any voltage Information.


My last try was to Change the Mode of 7i76e from 0 onto 2.

I hope one of you can give me an additionately Information to solve this Problem .

In the attachement you will find hal and ini files, may be there are some informations still missing. I worked
with a project given by talla83 (Youtube).

I switched from mach3 to linuxcnc and be shure it was a good decision.

Thanks to all

You forgotten to attach the hal & ini files.

You do have the read & write functions added to the thread ?

I forgot to do this once when using halrun when doing some testing.

Thank you BeagleBrtainz
now i added hal and ini may be you can see something wrong.
as i understood the man read and write are correct.

Thank you tommylight,

i forgot to addon the hal and ini file. This was done now.

I suppose your proposel is already part of hal.
May be a glance on my files will give you an additionately idea.

You may be better off starting with a pncconf created hal/ini file set

The field I/O on a 7I76E is not GPIO but rather:

Hallo PCW,

thank your for the fast Help.
At the Moment my Problem is solved. your assumption something
is wrong in HAL was Right.

Bye

Hallo Tommylight

I added the new working Hal file. Comparing to the old Hal file in my Question you will see at once my faults.

Not all io were tested, but works one they will work all i suppose.

Thanks to all.
