Hello Alan, You can start with one 7i96s.
Then you can add one 7i84. Then you can add 7i74 for 8 pieces 7i84. Or you can start with 7i96s + 7i74 + (2 to 9) * 7i84 imidietaly. I dont like sharing inputs. For control panel you can use input matrix.

The 7i96S is available (unlike the 7i76E, which would be another good choice) but it is a little short of IO, having one input fewer than you require. (And maybe you want a probe too? and some external alarms, coolant level sensing...( You can easily add extra IO with a smart-serial card such as the 7i84. (Though there are 17 unprotected GPIO pins on the expansion connector too, but using those as bare pins is something I would only suggest to the electronically confident) -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users " _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
