1. Design a program that will implement the following arithmetic operation.
Using a MOV instruction and place the value 45 in N7:0 and 286 in N7:1.
Add the values together and store the result in N7:2.
Substract the value in N7:2 from 785 and store the result in N7:3.
Multyply the value in N7:3 by 25 and store the reult in N7:4.
Divide the value in N7:4 by 35 and store the result in F8:0.
2. A. There are three part conveyor lines (1-2-3) feeding a main conveyor. Each of the three conveyor lines has its own counter. Construct a PLC program to obtain the total count of parts on the main conveyor.
B. Add a timer to the program that will update the total count every 30 s.
