Question
Please discuss on:
1. Simplify the truth table to Boolean equation or describe the And/Or logic relation within the IOs.
2. What is the function of Relay, R1? How it relates to your first ladder logic diagram?

Tool port (RS232C) Provide the inputs (X Use for connecting to the PC 4 Input terminal (6-pin)Not use in this exercise.] Output terminal (6-pin). Not use in this exercise.]Explanation / Answer
a). PLC truth tabe
R1 is On either X0 or X1 or both On
R1 is Off when X0 and X1 Off. This operation is same as Logic OR gate. Off means Logic zero, On means Logic one.
Y1 is On when both R1 and X2 On otherwise Off. This operation is same as Logic AND Gate.
Truth Table: Logic zero is Off, Logic one is On
Boolean equation Y0 = (X0 + X1) . X2
2). Relay R1 will control the Ouput Y0 with switch X2. Relay R1 is controlled by X0 and X1
R1 is the logic OR operation of X0 and X1. i.e boolean equation R1 = X0 + X1
X0 X1 X2 Y0 Remarks On/Off On/Off Off Off X2 is Off On Off On On both R1 and X2 On Off On On On both R1 and X2 On On On On On both R1 and X2 On Off Off On Off R1 is Off
