LabVIEW
labview security system with tcp/ip protocol
I would start by learning how to do TCP/IP communications. Look in the Example Finder (Help->Find Examples) for Simple TCP.lvproj. It contains a client and a server VI that you can learn from.
After that, figure out what each side of the communication should be doing and code that up.

please somebody help me out. I am currently a student and beginner to this entire labview thing...i was given assignment on labview cld security system topic but with a twist of using client server concept by implementing tcp/ip protocol...
I have no idea on even how to begin...can please someone help me...please am very desperate...please help me out
How to begin?? I assume you haven't even tried the basic "security system", so start with that. If you are not done in 4 hours, you are not ready and I recommend going back to the tutorials. If you made the code scalable and expandable, adding TCP/IP functionality should be an absolutely trivial thing that you can do at the very end. UDP is probably sufficient.
Are client and server running on the same machine or across networks. Who is server and who is client and what are their respective responsibilities?

hello there... now that i learned about the protocol, the thing that i could not able to figure out is the conditions which override an input without turning the initial output off.
Seems like you probably need to latch your inputs via Feedback Node or similar, and have cascading Select nodes or similar to determine the state of each output. (But I didn't try this to check how I'd do it, so if you can't make it work, that might not be true...)
Note that you'll still have to think about how to implement this in terms of multiple zones, since the instructions tell you to make this easy to add or remove zones without rewriting hierarchy. It's not obvious to me which hierarchy this refers to... perhaps VI Hierarchy?
As a side note, it's easier to understand your responses if you either address specific authors, or quote their messages like I did above.

hello, yes you are right i didnt try but thats because i am very new to labview, what i learned in school is basics, but the assignment given is very complicated for newbie like me.
You are definitely not qualified to solve a CLD style problem, so go to you teacher and tell him that.
From the NI documentation:
"A CLD demonstrates experience in developing, debugging, and deploying and
maintaining medium-to-large scale LabVIEW applications. A CLD is a professional with
cumulative experience of approximately 12 to 18 months developing medium to large
applications in LabVIEW."
Obviously, you don't have that experience. It is completely wrong and useless to throw students into the deep end with an assignment like that. You cannot learn anything this way.
Now maybe this is much simpler than a CLD security system. If all you need to do is change switches on one computer and turn on LEDs on another computer, you should be OK. There are quite a few very simple ways to do that. (For example network shared variables use TCP/IP.)
All you need is a client with multiple boolean arrays and a server with an array of colorboxes (see here). The client needs code to turn three booleans into a color, this can easily be achieved with a lookup table. No need for any boolean logic. Iterate over the three arrays and inside the loop turn each set of three booleans into an array and then use "boolean array to number" to index into an array of 8 colorboxes where each element is colored according to the state (you'll have some duplicate colors, of course).
First get the boolean to color working locally, then turn it into a subVI. Then add the network stuff. You should be done in 10 minutes. 😉
