In a large AGV system I have a group of several control points where I want to monitor the traffic levels. I have created a control point group that waits for a prearrival event to know when I am approaching any point in the group. What I cannot figure out is the syntax within the OnPreArrival event to know which control point out of the group created the token when the OnPreArrival fires. I can get the vehicle but I cannot figure out how to get the actual point being approached. THANKS!
Hi @Joe Hugan,
If you're trying to do this in Process Flow (Event-Triggered Source or Wait for Event activity), then this is where the "Assign Event Object To" option comes into play. This refers to the object that triggered the event, which in this case is the control point that an AGV is PreArriving to. See following image for reference: 
I hope this helps! Let us know if you have further questions. Thanks!
