PLEASE USE RSLOGIX WITH SCREEN SHOTS OF PROGRAM: In this lab you will be automating the operation of the conveyor system using

advanced instructions. The program is required to operate as follows:

$-$ Pushbutton S$\_1$ is used to manually latch $($M$\_$R ON$)$ and unlatch $($M$\_$R OFF$)$

the conveyor.

$-$ The fiber optic sensor FP$\_$S detects the TOTAL parts that go through the

line.

$-$ The inductive sensor IP$\_$S detects the METAL parts that go through the line.

$-$ The limit switch L$\_$S momentarily stops the conveyor $($M$\_$R OFF$).$

$-$ The red pilot light L$\_1$ must be ON when the METAL part count is greater or

equal than the NONMETAL part count and the TOTAL count is greater than

$0.$

$-$ The green pilot light L$\_2$ must be ON when the METAL part count is less

than the NONMETAL part count and the TOTAL count is greater than $0.$

$-$ The blue pilot light L$\_3$ must flash ON and OFF when the TOTAL count is

larger than $0$ in intervals given by the following relationship in milliseconds:

FLASHING $=1050(1000*$METAL$)/$TOTAL

$-$ Pushbutton S$\_2$ must reset all counts to $0.$

$-$ DO NOT use counters for this control process. Instead use ADD and

SUBTRACT instructions for the METAL, NONMETAL, and TOTAL

counts.

$-$ HINT: the value of FLASHING must be calculated as a separate integer

value $($N$7$:X$)$ and moved $($MOV$)$ to the PRESET values of the flashing

timers.
