Signal Error

Good afternoon, im trying to make a chain process with two mobile robots. Whats happening is the second robot takes of at the same time as the first one, but what i would like is for it to wait until the first one reaches the feeder, then start. I´ve tried with signals but doesn’t seam to work althought I tried with process buffer but doesnt allow for that exactly.

don’t use waitSignal-statement in feeder process routine,
Use Process Node and create product with the create-statement:
