O.K. state of play so far is that i have the back panel in the cabinet and i'm doing some electrical dwgs so i can at least give myself a fighting chance to get it right . i have a couple of queries before i go and start lashing in wires though. this is what i think i know from reading the posts , so i just need some nudging .

1......am i correct in saying that i need a separate input for the slave home switch?
2 .... i need a separate input for the rest of the home switches combined in series.
3... because i'm combining both limits and home into a single switch i must keep the e stop on a separate input.
4... i also need an input for feed / hold
5..... and an input for stop.
bring my total of inputs to 5 ( MAX. allowed)

i also have alarm terminals on my drive so i'm curious about how i can get these in to an input. i will post some drawings of my proposed electrics as soon as i'm finished.
