PickAndPlace blocked in simple model

Creator

Hello,

 

You will find attached a simple model where a worker unloads a MU in a buffer. Then the PickAndPlace loads the MU and unloads it in another buffer. After the second MU, the model is blocked.

 

Can someone explain to me what I'm doing wrong? The model has no custum code and therefore only uses built-in features.

 

Best regards,

 

Clément.

It seems you didn't do anything wrong.

 

I deleted and inserted a robot again

 

Now it works.

Thanks for your reply, but the model you posted is different (no loading time in PickAndPlace attributes).

 

When a loading time in the PickAndPlace and a unloading time in the workplace are set, the model blocks !!!

 

Its it a bug of Plant Simulation ?

yes, you are right!

 

It seems to have something to do with the constellation buffer and  pick and place which is not

 

working as expected.

 

I have exchanged the buffer1 with a placebuffer to get it working s. attachment.

 

Siemens should have a look at this behaviour.

It seems you uploaded the same model as befor. And what do you mean by place buffer ?

 

Thank you.

There is a bug in Plant Simulation when using a buffer for which the unloading time of the worker has started when the Pick&Place with loading time arrives.

The bug will be fixed in the next release.

 

In the meantime you can use a parallelproc instead of a buffer when unloading time and loading time are needed or work with other times to avoid this situation.

Sorry for the inconvenience.

 

Kind regards
