The invention provides a process for coating workpieces by plasma-induced chemical vapor deposition, in which a process gas is introduced into a coating chamber and a plasma is ignited by electromagnetic energy in at least one region of the coating chamber which adjoins the workpiece and in which the process gas is present, wherein the coating operation is monitored on the basis of at least one measured spectral parameter of the plasma, and the workpiece is removed in the event of a deviation from a desired range for the parameter.

The controller and method of the invention generate control instructions for a rotary machine that coats bottles. Gas is supplied to processing stations holding the bottles via a pressure management system. The processing stations are centrally controlled by a programmable PLC or microcontroller with an input device and display terminal. Since rotary machines need to be controlled differently depending on the type of bottles and the type of coating, different programs should be interactively created using the input device and display terminal, which then control the individual components of the rotary machine and the processing stations during the coating process. This eliminates unnecessary errors resulting from preparation of the different programs individually by a normal user.
