8 Tool Turret Comparision on Two Rungs

Hi,
I'm using classicladder for my lathe turret tool selection. I couldn't add enough of comparisons on one rung of ladder, so I broke it into two rungs. It doesn't work if I am going from 2nd rung tool to a 1st rung tool. What am I missing? How should I set it up for 8 tool comparison? Is it possible to have more spaces on a rung?
Thanks,
EW

One problem that I see is that you cannot have the same output coil in more than one place. Basically it cycles through and the one is off and the other on, they will do just that. On and off so fast that nothing basically happens at hardware level. I am referring to "trig2" in your ladder

Replace them with %B1 and %B2 respectively. Add another rung and place open contacts in parallel named %B1 and %B2 and connect them to a single output named Trig2.

So if either B1 or B2 is on, it activates Trig2

Note....assuming that B1 and B1 has not been used elsewhere in your ladder program....
