Put the six rungs into one rung - with all the contacts in parallel?

Thanks for your reply. Yes your drawing is right
But is there any way to combine them all like zrst resets up to 8 inputs at a time . Is there any ways to make inputs like that?

with ladder logic, if the 8 M contacts are consecutive beginning with M100

|--[ <> K2M100 K0]---------O---|
