An LD program calculates the output Z$,$ from two UINT variables, x and y$.$ The calculation takes

place in a function block that you must create yourself. The function block is programmed in ST and

the formula is given below:

z $=1050-$ xy$.$

Questions:

a$)$ Create the program described above, in Codesys to calculate the output z$.$ Be sure to show

the contents of both the:

i$.$ LD program

ii$.$ the ST function block.

b$)$ Simulate your solution in the Visual Simulation environment of Codesys to proof that the

answer is calculated correctly by your function block, for two different sets of x and y values
