             NEED ANSWERS TO THESE QUESTIONS IN DETAIL

The ABC co-operation chemical processing plant uses a computer to monitor the temperature and pressure of four (4) chemical tanks as shown in the figure below. Whenever a temperature or pressure exceeds the danger limit, an internal time sensor applies a 1 to its corresponding output to the computer. If all conditions are ok, then all output are 0.

Question 1.

If the computer reads the binary string 00101000, what problems exist?

Question 2.

What problems exist if the computer is reading 55 hexadecimal?

Question 3.

What hexadecimal number is read by the computer if the temperature and pressure in both tanks D and B are high?

Question 4.

Tanks A and B are taken out of use and their sensor outputs are connected to 1’s. The computer programmer must write a program to ignore these new circuit conditions. The program must check that the value read is always less than what decimal equivalent when no problem exist

Question 5.

In another area of the plant, only three (3) tanks (A, B and C) have to be monitored. What octal number is read if tank B has high temperature and pressure?

Duplicate threads. Keep the discussion in this one.

1. This question really has nothing to do with NI hardware or software, so it is only marginally appropriate for these Forums.

2. We do not do homework for people who post to the Forums.  If you have specific questions about understanding NI hardware or software that you may be using for your homework we will help you learn how to use them.

The questions you posted are very fundamental to understanding repesentation of data in binary (digital) systems. You really need to figure this out for yourself so that you thoroughly understand it. If we give you answers, you will not learn much.
