Retrofitting an 89 Chiron FZ12W aka Igor

I Didn't draw schematics.
Watt I did was map the connector plugged into the Sinumerik Control to Mesa Bord IO's with a spreadsheet. This is attached in the Data I sent you. I tried to copy the way the Chiron was controlled my Sinumerik drive. And used the connectors with breakout boards to connect to the Mesa boards.
It worked for me. But from my view today, I wouldn't go this approach again. I would wire to the Bords directly and skip the breakout and also change the old relay boards to modern DIN Rail ones.

No need for schematic I found everything in Wechslearme und IOs.ods , just send me when you arrive comressed backup.

Yea sorry this all is/will be a terrible mix of German and English.
Starting with good intentions making it all well documented and in Englisch and then getting lazy

In Europe, I only found mesa here:
www.welectron.com/#/dfclassic/query=MESA...bdf7c2dd7421b374f166
but unfortunately most of them are OUT OF STOCK
I wouldn't be surprised if Chinese versions of the cards appear at some point in time because they are not available outside the US



 

For two of my three retrofits I ordered them in the US and had them shipped over. Worked well.

As you can see, they don't have 7i77 and 7i92H, the closest alternative is 7i97 and 7iA0, but I have a much smaller number of outputs.
Perhaps the only way to combine the outputs from this I/O card and then to the relays is to get a larger number of available outputs.
or maybe you have a better combination, although yours is much better because if the analog DC drivers and motors fail, then
I just replace the analog 7i77 with one of the digital ones and the DC drivers and motors with AC.
