The major components for the retrofit are slowing coming together. One of the goals is to shrink the space required by the Pneumatics significantly.
To advance that goal, I have bought this valve terminal...
I need six valves, and a separation between a single service with dry air and the rest lubricated. Also a mix of 2 way and four way valves (which Festo doesn't do, so it will be 5/3 and 3/2 valves). This module was on ebay germany and is the closest I could find with its divider module, mix of valve modules, endplates etc. This Festo CPV stuff is like advanced lego
It comes with the Fieldbus electrical interface module which seems to support a few protocols.
I saw that there is a PyProfibus HAL comp in the github.
github.com/mbuesch/pyprofibus
The git hub has a dead link to pyprofibus hardware documentation
I have searched this forum for more information about this comp, and other than a link to the 130 page Ethercat thread, dont find any worked examples. Is there a simple way to control a Fieldbus device through mesa cards, and LinuxCNC with the pyprofibux comp? I dont see the lathe needing realtime control of it's pneumatics, as it all just stuff you use during set up. (Tool change, tailstock and collet clamping, coolant valve, backgear) Or should i just bite the bullet and buy a second terminal unit with a simple Multipol connector, and drive the individual valves with discrete wiring from Mesa outputs.

Thanks Andy, I suspected that would be the case. Luckily the multipol interface module for the CPV10 seems common enough.

The pinout is well documented in the festo manual:
