Waitwobj instruction

tabe03

Hello,

I have a problem when trying to connect an object in a conveyor:

I'm waiting in the waitwobj instruction and the conveyor is stopped, when I activate the sync switch it doesn't jump to the next instruction and continues waiting. Sometimes, although the conveyor is stopped it works well. And I dont't undestand that.

Is it necesary moving the conveyor to have waitwobj instruction finish?? Or can I connect an object although the conveyor is stopped??

I'm waiting for your replies!! Thank you!!
