Problem with Process Flow

new-bod-line-robot.fsm new-bod-most-updated-version-autosave.fsm

The attached model (new-bod-most-updated-version-autosave.fsm) is facing the following issue: even though the process flow seems to be correct, the robot and the processor (BoD) stop working after the first flow item passes through the first combiner. I have another model similar to this one that works well using the same process flow that is also attached to this question (new-bod-line-robot.fsm). If someone can identify what I have been doing wrong so far that will help me a lot.

Thank you.

The problem is that your token is creating a 3D Box on the Queue, which immediately moves the created flowitem (door) onto the conveyor BEFORE the token has entered the Wait Until on Conveyor activity. Since the event has already fired, the token never leaves that activity to create the carton. This works in your other model because there is a conveyor in between the queue and conveyor you're listening to.

One way you could solve this would be to kick off child token that would handle the creation of the 3D box. Add a Delay activity before the Create 3D Box with a delay time of 0 so the parent token is already waiting in the Wait Until on Conveyor activity when the flowitem is created. You may also want to check the box Label Access on Parent Only in the Create Tokens activity so your reference to the created flowitem is added to the parent on not just the child token.

I've attached an updated model that works correctly.

I modified your model (see attached). Would something like this work for you?
