Draw the input and output PLC interface and the ladder logic program to replace the relay ladder logic in the process reaction tank in Figure D-1. The ladder logic is used to control a process reaction tank. Interface the input field devices to the same input module using terminals follows: selector switch NO to 1, selector switch NC to 2, flow switch to 3, and temperature switch to 4. Interface the 28 VDC output field devices to output module terminals as follows: fill valve to 1 and drain valve 2. Interface the 120 VAC output field devices to terminals as follows: mixer motor contactor to 1, heater motor contactor to 2, and pilot light to 3.
