Pre arrival event does not fire when traveling offset

Hi,

In the attached example model the AGV gets a travel task to the third control point in the picture, with a path offset of -0.5. This means that the AGV stops at the position from picture 2:

We would expect that the pre arrival fires for the first two control points, but it only fires for the first control point. It looks like the pre arrival does not fire when using path offset for both control points where the AGV stops between. Is this how the pre arrival event works when using path offset? Or how do these two work together?

Thanks,

Patrick

Hi @Matthew Gillespie is it correct that we cannot see those new releases in the Downloads section of our account?

This looks like a bug. I will email into the Dev team.

When the offset is negative the destination cp is never allocated and the cp before the destination cp does not have a pre arrival event.

When the offset is positive the destination cp is allocated but there is no prearrival event.

Making the offset value tiny does not change the behavior. Making the acceleration and deceleration values small also doesn't have an effect. Changing the Task executer to be smaller does not change the behavior.
