If you have combined home/limit switches it would be more like:
net min-home-x hm2_7i95.0.inmux.00.input-8 joint.0.home-sw-in joint.N.neg-lim-sw-in
(assuming N/O switches) or
net min-home-x hm2_7i95.0.inmux.00.input-8-not joint.0.home-sw-in joint.N.neg-lim-sw-in
(assuming N/C switches)
and you would have to set the "HOME_IGNORE_LIMITS" flag true for that joint in your INI file
INCOM8,9 is the input common for inputs 8 and 9 so for example you could connect
INCOM8,9 to +24V and grounding inputs 8 or 9 would set the corresponding hal pins high
Alternatively you could connect INCOM8,9 to ground and then supplying +4 to +24 on inputs 8,9
would also set the corresponding hal pins high. Each group of 2 inputs has a separate common
