Thanks Dan,
No SS, its got a Scorpion in it.
FRO, SRO and all buttons are via the PLC so no PoKeys, I prefer everything to be 24v if possible, thats why I am making up the BOBs for my ESS as I like differential signals if 5v and 24v for other I/O.
Spin enable is a latching switch with LED ring round the button.
The limit one is an override so I can back off the limits. The limits dont go to Mach they are handled by the PLC, if a limit is hit the PLC takes the enables away from all drives and also sends an E-Stop to Mach. To back off the limits I have to press and hold that button and I can then jog off them.
Control is simply the button that powers up the computer and other bits and pieces.
I got a couple of relay boards from Russ, think he picked up four or five somewhere and he kindly sent me a couple.
