Problem No. 1: (30 pts.) Design a PLC ladder logic program to control the operation of an alarm system consisting of three (3) Horns (HORN_1, HORN_2, and HORN_3) and four (4) normally open proximity sensors (INPUT_1, INPUT_2, INPUT_3, and INPUT_4) using the following sequence: - - HORN_1 and only HORN_1 must be energized if any two and just two of the sensors are activated. HORN_2 and only HORN_2 must be energized if any three and just three of the sensors are activated. HORN 3 and only HORN_3 must be energized if all four sensors are activated. Notice that no two Horns can be activated at the same time. Do not use latch and unlatch instructions. Assign sequential addresses to the input and output devices starting from bit 1.
