The normal practice of triggering the rung with the shift instruction is to tie it to any machine movement during index activities with some interlocks to prevent false triggering.

You can include the machine stop or alarm condition in the interlock to prevent it from triggering.

Does the machine have an encoder? Or an index / on station sensor?

Take a look at my code here:

It's RSLOGIX 500
