How to link inputs ,outputs for Mesa 5i25 7i76 was created by finemeca
Hello,

I continue my tests with the mesa and 5i25 7i76 cards.

In the doc :

www.linuxcnc.org/docs/html/drivers/hostmot2.htm

I do the command:
Code:
dmesg > hm2.txt

Warning: Spoiler!



If I understand is the inputs and outputs of the 5i25

In the manual 7i76, page 8, I list Field input / output connectors and TB5 TB6

Example :

TB6 CONNECTOR PINOUT
TB6 PIN I/O

1 INPUT16

An example with pncconfig:
Code:
# --- COOLANT-MIST --- setp hm2_5i25.0.gpio.017.is_output true net coolant-mist hm2_5i25.0.gpio.017.out Installation du driver


My question is how to link an input or output TB5-TB6 ???


Thank you in advance.

Pierre

I think the pin name for the IO on a 7i76 should look something like this
hm2_5i25.0.7i77.0.0.input-03 (for an input )
or
hm2_5i25.0.7i77.0.0.output-01 (for an output)

But you can easily check the pin names from Hal Show.

In Pnconf the io pins are not listed under GPIO, they are dedicated inputs and outputs under smart serial (I think).

PS: You have to have the field power connected to the 7i76 board for the field io to show up.

Hello Todd,

Thank you for your help.

This is what I do not understand!

W1est left and I use the 24v on TB1 to pin 1 and 8

Not included ....

on 7i76 or is this output:

hm2_5i25.0.gpio.017

Where is the gpio 017 ?????

With a multimeter on TB5 and TB6 I only 0V to terminals ???

Or with :
Code:
halcmd: setp hm2_5i25.0.7i76.0.0.output-07 true

24v --> output7 Tb6

hm2_5i25.0.gpio.0xx refers to a pin if unused for anything else on the 5i25. The pin hm2_5i25.0.gpio.017 would be the first pin on the 2nd port (the header pins on the top of the card) of the 5i25 card.

hm2_5i25.0.7i76.0.0.output-07 would be pin #24 on TB6. Test it by probing from it to the ground (pin8 TB1) of the field IO with your multi meter.
