New product on input whilst warehouse is full, bricks factory.
lennartmureau opened this issue · comments
In the function block "PGR_HBW_Ablauf" during li_StepCase 50 the program searches for an available space in the warehouse for the product that was just inputted. There is however no check if a valid position is found or if the warehouse is full. This results in the warehouse getting stuck in this case indefinetely. The robot (VGR) is waiting for confirmation from the warehouse, which never arrives. This effectively bricks the entire factory.
When this situation is present it can only be fixed by manually changing tags on the PLC or restarting the entire system.
