Ladder diagram for a PLC program
Draw the ladder diagram for the following PLC program.
A batch process which involves filling a tank with liquid, mixing the liquid and draining the tank, is automated with a PLC. The specific sequence of events is as follows:
When the start push button is pressed, a fill valve V1, opens and lets a liquid into the tank until it is full.
The liquid in the tank is mixed for 3 minutes by running an agitator (motor).
A drain valve V2 opens and drains the tank.
