Setting AGV state while unloading?

Hi Team,

I am trying to set the AGV state to "Blocked" while it is at drop point but its state is not changing to "Blocked". By default, it's "idle". I have used here breathe activity just before changing the state but still it is not working.

Can you help to understand where is the problem?

Thank you!

You are setting the state only after the token is released from the Wait For Event activity. So the state is immediately overridden when the AGV unloads the item.

You are also using state names that differ from the default states (capitalization matters!). Due to this the states are not appearing in the state chart, because they are not part of the State Table the chart is linked to. To prevent this, when you want to use default states, use the STATE_... defines.

Hi @Felix Möhlmann,

Thank you for your answer!

But I have one question here:

We are setting the state to "Blocked" when wait is over. That is not correct.

As per per the flow, state will be changed when token comes out from "wait for Queue Content 0" not when wait is happening.

Can you help me to understand?

Thank you!

You want the state to be 'blocked' while the AGV is waiting for the queue to empty, correct? For that, the state has to be changed before the token enters the Wait for Event activity.

Maybe you are confused by the connector arrows? A block of activities is always executed from the top.

Yes, I was confused with connectors.

Thank you so much! @Felix Möhlmann
