Emco PC Turn 50 retrofit 7I96S

Hello
I starterd to retrofit My Emco and got some questions.
I managed to instal mint 21 beta and linuxcnc 2.9
I got both axis moving and now want to add limit switches.

My Emco has microswitch and proxysensor. I think they both work on 24v
Proxysensor is pnp type (3 wires) microswitch has 2 wires comming out. 
How to connect them to 7i96s Card? (what pins to use)

I connected the microswitch like this and got it working
microswitch 1 wire to 24v power +
microswitch 2 wire to digital input 0
I/O common I connected to my 24v power -
Then on the pnconfig I choose input 0 to be combinated home + x negative limit

Still dont know how to wire this proxy I think I will do it like this
proxysensor 1 wire to 24v +
proxysensor 2 wire to 24v -
proxysensor 3 wire to digital input 1
But I dont know what to choose on the pnconfig? there is no proxy sensors on the list.

Edit: I notice that If i choose pconfig tb1/tb2 screen encored to  x encoder  Then there is possibility to choose "use encoder index for home"
So Is this way to go ?
But if I want to use spindle encored that is not possible anymore besauce the only encoder input is used?



Do I need to buy a new mesa card that has more encoders?

Thank you for your patience.
First, the version of LinuxCNC used for Mint 21 is the same as in Debian testing, so it is from April of this year, but support for Mesa 7i96S was added in Jun i think, so it will not work properly, most probably.
You can uninstall that version and compile the latest version of LinuxCNC to get full support for 7i96S.
And no, you do not need more cards, 7i96S should have 11 inputs that can be used with all types of switches, although some might need a resistor to be added.

But I dont know what to choose on the pnconfig? there is no proxy sensors on the list.

pncconf (and LinucCNC) don't care about the sensor type, only the function (limit home probe etc) and the input pin

I am trying to figure out the tool turret. 
I got sample hal file and change it to  work with my 7i96S

I didn´t touch these lines, I think they ok.
#  ---toolchange signals for custom tool changer---
net tool-number             <=  iocontrol.0.tool-prep-number
net tool-change-request     <=  iocontrol.0.tool-change
net tool-change-confirmed   =>  iocontrol.0.tool-changed
net tool-prepare-request    <=  iocontrol.0.tool-prepare
net tool-prepare-confirmed  =>  iocontrol.0.tool-prepared

This custom.hal I need to change.
But I dont know how should I change this line "net turret-home-command classicladder.0.in-04 motion.digital-out-04"

#classicladder commands for turret control
net turret-home classicladder.0.in-01 hm2_7i96s.0.inm.00.input-04

"net turret-home-command classicladder.0.in-04 motion.digital-out-04"

Is hardware independent so should work the same for any LinuxCNC  hardware setup.
 

I had to commented it out (#)
otherwise there is an error
