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.

The solid state devices designed to perform logical decision making to control the equipment is a. Switches O b. Programmable Logic Controller O. Relays The symbol used for output device in PLC is а. Ob. HE O d.

Define in short about PLC.
