Hello:
I hope you soon have the simulator installed on your PC and can test the system you mentioned in this thread.
As you know, this type of programming can be tested separately, since the messages are what connect the elements. This makes it quick to program and allows for many possible combinations. I have created a control to show all users the status of the shelving, both when a pallet enters and when it leaves.
I welcome suggestions from users to try and implement in the project.
Regards
