cpdeallocate does not work correctly

Hi,

I have made a small example model to show my problem. One AGV (top one) arrives at a cp, at which point I use cpallocate to allocate a controlpoint on a separate network. After 100 seconds I use cpdeallocate to release the cp. This works fine, as can be seen in the tree, but my second AGV which is waiting for that same control point does not start driving.

How can I make this work? Is there some function I need to call to let the second AGV know that it is able to travel again?

Many thanks for your time,

Patrick

Is it a timing issue? Maybe the second AGV is trying to acquire the control point before it is made available and thus it can't successfully allocate it?

Hi @Tanner Poulton,

That is more or less the point in this example. The second AGV is trying to acquire the controlpoint before it is made available. But after the cp is made available by using cpdeallocate the agv does not start driving again. Do you know how to let the second agv start again after the cp that he need is released?

cpdeallocate() should be alerting the other AGV that it can go now. I'll debug it to see what is happening and let you know.

This is a bug. I've fixed it for the next bugfix releases.

To fix it in the meantime, you can replace C:\Program Files\FlexSim 2018 Update 2\modules\AGV\AGV.dll with the attached AGV dll.
