ABSTRACT
This text has chiefly been studied in the process of production , and applies the program and the superiority of PLC's control shop traveler work . The most before all others definition of the programmable order controller and major merit introduced can reach the superiority . Then expound the application domain of shop traveler . Major how introduced with PLC's control shop traveler work , as well as the tradition is controlled and the contrast of PLC's control . Stand side by side the trapezoid picture of outside wiring diagram and the program of I/O of electric control line Lu Tu thread Lu Tu PLC of detail . Moreover the detailed program is finally still had in this text . In a word it can make reader clearly know the big and powerful superiority with the programmable order controller control shop traveler .
The keyword : PLC Shop traveler Process of production
