- Write a Ladder Logic PLC program for each of the following scenarios. Label all contacts and coils in the PLC program. Scenario 1 Turn on a light when either one of two switches (I1, I2) is toggled on (construct an OR Gate). Turn on a second light when both switches (Same inputs I1, I2) are toggled on (construct an AND Gate). Turn on a third light when both switches (Same inputs I1, I2) are toggled off (construct a NOR Gate). Turn on a fourth light when either switch (Same inputs I1, I2) is toggled off (construct a NAND Gate). Print a copy of the program showing the construction of the four gate configurations. Also, submit a truth table for the four input configurations. Then modify your program so, only one light turns on at a time as you toggle the four truth table states.
