pncconf does not know about the field output options of the 7I76EU
(it only knows about the 7I76E)

The 7I76EU  has individually settable output modes for each output.

The default setting is sourcing mode on all outputs.

Sourcing mode means the 7I76EU outputs supply positive field voltage to a ground referred load
This is identical to the original 7I76E.

To set up sinking or push-pull outputs you must set the source or sink
parameters. These parameters are 16 bit numbers where each bit determines
the output mode of a single output. Bit 0 in the source and sink parameters
control the operation of output 0 and so on.

The default setting is source = 0xFFFF and sink = 0x0000 meaning all outputs are set to
sourcing mode.

To set to sinking mode, you set the desired sink bit to 1 and the corresponding source bit to 0
 To set push-pull mode, you set both the sink and source bits for the corresponding output.

That is if you wanted the first 8 outputs (0..7)  to be sourcing and the last 8 outputs (8..15) to be sinking
you would set the source parameter to 0x00FF and the sink parameter to 0xFF00

This is described on page 17 of the 7I76EU manual

Note the these parameters cannot be set dynamically, they must be set with setp commands in the hal file.

 

Die Eingänge laufen bei mir wie gewünscht, leider bekomme ich die Ausgänge nicht in Betrieb. Ich möchte gegen Gnd schalten, passieren tut nichts

Nachtrag: Verdrahte ich Output 0 auf TP6 als Schalter gegen + 24V (d.h. die Last liegt auf der anderen Seite an Masse) dann funktioniert es. Ich dachte die 7i76EU hat Universal Outputs, d.h. kann beide Modis?

I fixed the missing 7i76eu from the stepper boards variable which caused a partial build of the main.hal file and leaving out the enable and the stepper setp lines.

Can you attach your ini file?

Did you skip Drive 0 and Drive 1?

Gerne, aber ich bin noch nicht sicher ober der Parameter "7i76 Modus 2 I/O card" so richtig gesetzt ist oder ob ich Linux doch noch auf "UTF-8 EN_US" umstellen muss.
Nachtrag: Zumindest funktionieren jetzt die Endschalter (kann den Status in LinuxCNC richtig sehen, die Schalter ändern sich auch

Hallo Raspll,
danke für deinen Post! Jetzt wird mir einiges klarer.
Ich arbeite mich gerade durch das Handbuch um HAL und INI händisch anzupassen.
Genau aus dem von dir beschriebenen Grund.
 

But If I don't select "7i76 Modus 2 I/O card" my settings are lost after closing and reloading Pncconf. 
Do I have to select Modus 2 anyway even If I change locale to UTF-8 EN_US ?

ok, after searching for the missing tab i found this post  
After enabling the option „Show advanced config pages“ I could modify the value "0: 7i76 Modus I/O Kart..". After modification the tab 7i76 I/O (SS#0) is available, now. 

Use the LinuxCNC ISO written to USB to boot the PC in English language, start PncConf to make the config, save it on the hard drive or another USB.
Or change locale to UTF-8 EN_US

I don't have the tab with "7i76 I/O,

 

You should get a screen like this:

 

If not. it may be that you have hit a locale bug in pncconf and may have to
temporarily set the locale language to  en_US to work around the issue.

Hallo,
ich bin gerade am Umbau einer ISEL CPM3020 von IMC4 auf MESA 7i76EU. Die Kommunikation von LinuxCNC zur Karte funktioniert.
Aktuell hänge ich an der Konfiguration der Referenz- und Endschalter fest. Ich versuche via Pncconf die Pins festzulegen, finde aber im Menu "Mesa Karte 0" nur Zuordungen für TB2/TB3, P1 und P2. Bei P1/P2 könnte ich die Schalter zwar anlegen, dann bekomme ich aber Pin Nummern die m.E. mit den Field I/Os nichts zu tun haben sondern nur mit den I/O Expansion connectoren. Ich habe trotzdem mal darüber die Schalter konfiguriert, das Ergebnis sieht in der HAL Datei dann wie folgt aus (Leerzeilen entfernt):# externe Signaleingänge
# --- MIN-HOME-X ---
net min-home-x     <=  hm2_7i76e.0.gpio.017.in
# --- MAX-X ---
net max-x     <=  hm2_7i76e.0.gpio.018.in
# --- MIN-HOME-Y ---
net min-home-y     <=  hm2_7i76e.0.gpio.019.in
# --- MAX-Y ---
net max-y     <=  hm2_7i76e.0.gpio.020.in
# --- MIN-Z ---
net min-z     <=  hm2_7i76e.0.gpio.021.in
# --- MAX-HOME-Z ---
net max-home-z     <=  hm2_7i76e.0.gpio.022.in


Eine Konfigurationsseite für TB5 oder TB6 zur Konfiguration der Field I/Os kann ich nicht finden. Wo ist mein Denkfehler? 

I just did this for my CNC. Here are the HAL bits I used.  Amusingly, I can't find where <axis>-fault is connected, but I *do* get following errors when I hit things.  More testing required...

I have had loong time before network tunning done this ... it is basic stuff for latency reduction at any hardware

I will do the kill of EEE and I will share the resaults in comming weeks .. thanks for hint !

regards 

I did not get a working stepper configuration out of MesaCT with a 7i76eu. I have posted the output and my working config here forum.linuxcnc.org/configuration-tools/5...erated-configuration

The output was supposed to be on the 02 stepper but it was connected to the 00 stepper. The feedback loop was not closed and it was not set to be in velocity mode. Look at the two configurations.
