Industrial Motor Controls 14.a. Single sweep operation of a PLC is normally used to A. produce an output when a timer reaches preset value. B. issue a RUN command to the PLC. C. create a negative transition output coil. D. debug newly written ladder logic. 14.b. A photoeye will have which of the following abbreviations? A. PHOTO B. PE C. PHEYE D. PEYE

Exercise-2: Design a PLC program and prepare a typical I/O connection diagram and ladder logic program for the following motor control: W Three starters are to be wired so that each starter is operated from its own start/stop pushbutton station. . A master stop station is to be included that will trip out all starters when pushed. . Overload relay contacts are to be programmed so that an overload on any one of the starters will automatically drop all of the starters. . All pushbuttons are to be wired using one set of NO contacts.

Define in short about PLC.
