Project Description: The aim of Field I/O And Logic I/O Boards In Programmable Logic Controller project is to design and implement application logic for controlling certain parameters solenoid valves,fans,heaters,dampers etc.

. In existing system manual methods are used for controlling these systems. In present electrical systems relays are mostly used for controlling these systems. In order to switch on and off these systems relays are used where there is no need of mechanical work involved it works on programmable logic controller.

With the introduction of Programmable logic controllers it had became a important part of electrical control systems. Using PLC’s can reduce cost of complex systems and increase flexibility.
