7i96S card arrived what setup is recomended

PNP for mixed voltages...

But I don't think you really need mixed input voltages, as the Enable is an output
and the ALM signal is just an OPTO output

For 24V NPN proximity switches:

+24V --> 7I96S input common

NPN proximity switch 0utputs --> 7I96S isolated inputs

ALM+  --> 7i96S isolated input

COM- 24V COMMOM

Note that you could parallel the ALM outputs to save inputs

the ALM signal is just an OPTO output

The ALM is an OPTO output from the CL57T right? According to the manual section 6, it shows that I need to supply 5-24v DC to that circuit. Can I just use my 24v field power for this? Doesn't it matter that I have the driver setting S3 set to 5v (due to STEP/DIR 5v signals)? I don't want to fry this thing before I get going.

Note that you could parallel the ALM outputs to save inputs

This was the plan.Also, how do I use a spare STEP/DIR for ENA? Is that in my HAL settings? The manual mentions:

ENA must be ahead of DIR by at least 200ms

According to the manual section 6, it shows that I need to supply 5-24v DC to that circuit. Can I just use my 24v field power for this?

No, the output can switch 5V to 24V signals but should not be directly connected to a power source for sinking (NPN) operation

The ALM output would wire directly to a 7I96S input as shown in my table.

The drives 5V/24V switch only affects inputs (PUL,DIR,ENA)

Note that the ENA input is actually a  DISABLE input so not really of much use unless you change it's polarity.
(because the drive would be enabled if there is no controller power which is a bit crazy)
This likely requires the use of the (windows) software setup utility for the drive. Similarly, the ALM outputs cannot be
paralled unless re-programmed to be ON for alarm rather than the default OFF for alarm, They could possible be connected
in series instead using the default (OFF for alarm) setting

To use a step/dir pin for ENA, you set the number of stepgens to < 5, freeing up the GPIO pins that connect to say stepgen3 or 4
you then use the GPIO pins in hal to control the output state of these pins.
