There is no dial table object in Plant Simulation.
Normally it is sufficient to model these tasks using SingleProcs and the block Cycle. The time for rotate the plate you can set as recovery time in the singleprocs. The behavior is close to the dial table.
But if you neet to show the rotation of the table (e.g. for 3D representation, customer demand...), you can develop your own dial table e.g. based on a transporter.
