Hi eloid,
It's really hard to come with a generic thing that works for everybody since all systems are different. I took a quick stab at it and the result is in the attached screenshot.

S1 and S2 are two E-Stop buttons (normaly closed of course)
S3 is your enable switch, press this to enable the system.
S4 is used to override the limit switches so that system can be enbaled in order to jog off the limits.
S10-S15 are your six limit switches, add or remove as you see fit.
S16 is another switch you can use for whatever you want to - safety door or or what not.

Is that somewhere close to what you are looking for?

EDIT: Schematic removed, see better version in next post.
