Hi,

The first problem is that you are setting on each variable in labels named "PE1A" and "PE1B" but in the decide activity you ar asking for labels "PE1AState and" "PE1BState".

Then, names of photoeyes are not following this rules, so the variables and the logic are not referencing photoeyes correctly.

So create the logic based on photo eyes named with this rules.

I hope it helps you!

You have to rebuild the model following those rules. If you just change the names the logic will be wrong becauser Emulation Variables will not point the photo eyes they should.

Also, in the Decide activities you are still asking for a label that don't exist on the token. You have change the Get Varialbe assign to "token.PhotoEyeState" but in the Decides you are asking either for PE1AState and PE1AState
