You are given the following parts: 1. Two start/stop stations. For each station, the Start pushbutton is a normally open pushbutton, while the Stop pushbutton is a normally closed pushbutton. They are named as StartA, StopA, StartB, StopB. 2. Two motors: motor A and motor B, namely MotorA and MotorB 3. Two motor starters: Each motor starter consists of standard components including coil, main contact, auxiliary contact, overload protection contact, and heat element, which are named as HEAT_A, HEAT_B, respectively....

In this exercise we want you to apply your knowledge of Relay Logic Instructions to design a program which will control the garage door system. The Door System includes: • A reversible Motor (Q4.0 moves the motor up and Q4.1 moves the motor down) • A pair of Limit Switches (I0.3 for top limit switch (LS1) and I0.4 for bottom limit switch (LS2) ) • An Operator Control Panel (Three pushbutton open (I0.0), close (I0.1), and stop (I0.2) , and...

Assume you are hired to write a program for a company that manufactures electronic components. The system is shown in the figure below. A controller stops the take-up spool at a predetermined amount of resistors (75). A worker on the floor then cuts the resistor strip and places it in a kit. Write a program to count and control the number of resistors placed into each kit. THIS HAS TO BE WRITTEN IN LADDER LOGIC. The controller operates as follows:...
