In this way, the control means controls the processing equipment, and the progress of the work of the processing equipment is displayed on the display means.
This makes it possible to provide a processing line system having excellent expandability and versatility.

Further, according to the control apparatus for processing equipment according to the invention of claim 7, claim 2 or claim 3 or claim 4 is provided.
7. The control device for processing equipment according to claim 5, wherein the processing line includes one of a U-shaped line and a batch line, so that the operator operates while moving on the U-shaped line or the batch line. By manually operating the switch, the processing machine etc. is started or stopped,
The processing equipment is controlled in response to a signal from the option unit, and the progress of the work of the processing equipment is displayed on the display means.
This makes it possible to provide a processing line system having excellent expandability and versatility.
