hurco hawk 30 retrofit

Hi All,
I have a hurco hawk 30 VMC which was retrofitted with siemens 802C system. it has yazkawa analoge drives . I would like to retrofit to LCNC. what is the best plan ? please see pics below , machine is in good mechanical condition

Thanks Tommylight . I am going through posts.
What you think about retaining Analogue Drives . In your experience will they give trouble later.

These drives are hardly used . Ill take a chance .
Hawk -30 is a basic machine.The machine don't have an ATC , has manual speed change for spindle..
From my study I got the idea as below..
MESA card with 4 Analogue channels need to be selected.(7i33 ?)
just need ~ 20 I/o for PLC (Do I need additional card for this?).
I noticed you are using lot of cards "7i92, 7i77, 7i74, 7i70, 7i71 and maybe another 7i84 and 7i73 for pendant". Why is that?.
Sorry.. too may questions . I am a mechanical engineer.
If you have a wiring diagram it will be very helpful.

Thanks Tommylight for the reply. I went through MESA site and came across this
store.mesanet.com/index.php?route=produc...83_86&product_id=344
This card 7i97 connects to PC via ethernet and gives analogue and digital I/Os directly, only single card is required.
Is it used by LCNC community?. I see most users prefer combination of 5i25 +7i77. any reason for this.

I believe that the 7i97 is a relatively new offering from Mesa. (less than a year old) You will see a lot more info about the 7i77 because it has been around for years and therefore has many more users. I think I installed my 7i77 more than 8 years ago.

Looks nice!
