Nevertheless, CNi developpers use comunication protocol another then Modbus or EtherCat. It's their own protocol, IOS as they call it.

That's why I need to remove old IO boards and send them to trash.
My question is to MESA developers to help me to get right boards.
I have two cabinets:
Cab1 (main with servodrives and frequency inverter), it has 9 digital inputs and 9 DO, servodrives are operated with analog signals.
Cab2 (installed on cnc machine it serves all valves, drilling heads, limit swithes, etc.) in total: 37 DI (24V pnp) and 63 DO (pnp transistor 24V).
I suppose, that I will not use some of them in extreme necessity.
What boards is best to suit this vast amount of inputs/outputs.
As for Cab1, I suppose PCI interface is fine 5i25+7i77.
But for Cab2, it would be nice to install Ethernet interface 7i92 + something.
What would you recomend me for this thoghts? Does they could be joined?

PS
I'm not lazy men. I will reconnect some inputs/outputs from Cab2 to Cab1.

If the control PC is mounted in CAB 1, then a 5I25/6I25+7I77 is fine
If not, a 7I92+7I77 would be a better choice

If you want a separate control card in CAB2. I would use a 7I94+
2x 7I71 and 1x 7I70 (96x 24V outputs and 48x 24V inputs)

I would use a 7i77 in the servo cabinet, then two 7i84 cards in the other cabinet. The two 7i84 remote serial cards would give you 32-in, 64-out. Then to interface with them have a 7i74. It could be mounted in either cabinet, probably put it close to the FPGA you choose, because the serial cables can be quite long, The FPGA card would be either a 5i25,6i25, or 7i92, what ever you prefer. The 2nd cabinet might be a short a few inputs, but you would have plenty of extra in the servo cabinet, if you can move a few (5) over from the other cabinet you'd be covered.

I don't think I knew about the 7i94 card. Couldn't he just get by with one of those, connect the 7i77 to it and run the smart serial cables to the other cabinet?

Yes, I think there's even a config for that

Controlling PC will be in CAB1, so as I understood, I can
1) take 7i94 card and connect to it 7i77 (in that parallel port. What cables for that purpose I can take? I need to manufacture them, or MESA has it's own?)
2) wire 2 ethernet cables into CAB2 and connect 2x 7I71 and 1x 7I70.
3) then configure somehow, don't know how all this boards.
And voila!! it will work!

Yes, in general, some hal editing required.

tommylight, parallel cables are plenty for sale, could you give me some reference or at least to tell what their right name?

Hello!
How did this project turn out? I also have a task to retrofit a Biesse machine and it has these CNI SIR88 IO modules. I have done another Biesse retrofit for the same guy 3 years ago, but that machine was older and a lot easier - it had an array of relays in main cabinet for outputs and optoisolators for inputs - it was a long, but simple task to wire them to Mesa boards.
Now I am puzzled on how to get this thing done.
1) how did you solve the IO bits - did you put remote serial Mesa card on top of the machine for control of all the drill bits etc?
2) how did you control the servo drives? I am more interested in how it was handled in HAL. Did you connect commanded velocity to analog output and encoder to position feedback without PID module (as I am thinking that PID loop is closed in the servo drive and it is running in velocity mode)?
3) how did you control the VFD of the spindles? the machine I have to deal with, has VFD with RS-485 port. Is it safe to assume that it is Modbus?
