7i96s +7i83 trough 7i44 is it possible?

Hello, is it possible to connect these three cards, it is a plan to retrofit a lathe with siemens analog amplifiers.. ?in case it can't 7i96s+7i77 can 

Yes you can do that but you might be better off
with a  7I92TM +7I77 or 7I97T

I have a 7i92
P1 > 7i76
P2 > 7i74 > 1 port to a 7i83 (for spindle control plus some extra "things") and another port to a 7i73

The 7i74 might be a better fit as it has a 25 pin connector that matches the 7i96s connector where as the 7i44 has a 50 pin connector, tho it wouldn't be impossible.

thank you very much, I have a 7i96s , so I thought I'd use it in combination with a 7i74 i also have, so I thought about getting a 7i83, i only need it for two servo motors+ spindle, 7i83 it is cheaper variant in that case.

sorry I made a mistake, I have 7i74 instead of what I wrote 7i44

A custom cable wouldn't be difficult, if not mesa has this.

The issue with a 7I96S+7I74 is that there's nowhere to add the second encoder
(well you could have strange 7I96S+7I74 firmware that puts one differential encoder
on the RX lines of 3 of the 7I74s RJ45 connectors)

Edit: you need three encoders: X, Z, Spindle.

You could use a 7I96S+7I85+7I83 but a 7I96S+7I77 might make more sense

thank you, I made a mistake, I have 7i74 instead of what I wrote 7i44

thanks, then I will buy a 7i77 and I solved the problem with cards:)

 

my friend just repaired the 7i77 that I had and broke it with a short circuit (he says it's a dc-dc converter), in case it's successful, I'll try to connect it with the 7i96s...my question is, in that case, can I use the spindle output and encoder from  7i96s plus mpg and I/o, and with the 7i77 also use the I/O plus analog signals for the drivers (siemens amplifiers)?
