Hello to everybody!
My task is to write program for testing a control cabinet, if it was built and wired correctly. Inside the cabinet is PLC (industrial controller, for example, Mitsubishi FX3u).The program itself supposed to run on a laptop with Windows OS. The laptop is connected to PLC programming input through USB port.
During the test, some action will be advised on screen, for example: "Connect +24V to terminal 233". Then the corresponding input of PLC has to be checked and evaluated. If it is high, signal and message "OK" to be created. If not-"Error" signal generated. After finishing test all signals are to be saved into a text file for documentation.
Questions.
1. What should I start with? Which software package is better? Visual Studio? Version?
2. Which language is better: C++,C#, VB or..? Personally, I prefer C#, but before this language appeared, many solutions were published.
3. Which drivers, ActiveX or something else what is needed for communication can be used? Where to get them?
Thank You in advance, Wal

Honestly, if you are asking these questions, then maybe you are embarking on the wrong project?
Is this a homework assignment?

Hi....have you tried turning it off and on?

Start by paying attention to what is around you: look at the top of this page.
See the bit where it says
"Technical discussions are encouraged, but click here to ask your programming question."
Click the bit.
Ask there.

Have you tried turning it off and on again?
1) Open eyes, read manuals carfully
2) Understand what the letter present you and form words in mind
3) Use the correct forum!
PS: Saw i got ninjad 10 mins ago :/
if(this.signature != "")
{
MessageBox.Show("This is my signature: " + Environment.NewLine + signature);
}
else
{
MessageBox.Show("404-Signature not found");
}

Sounds fun, good luck on your task!

Thank You. Actually, I did similar task, but, it was for specific HMI, not for widely used laptops.

And if it's not wired correctly, your 24V feed to you -5V input will not make for happy results.

Hi.
Thank You for the reply. We don't use -5V inputs in our cabinets, 24V only. Anyway, control cabinets have to be tested somehow.

The question is: who is the bad guy here?
Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

Probably, but I would give amnesty to the hackers...

Including the hosting company and all those that keep it running, the payment processing company(ies) and all those who keep them running, general society, the media, celebrity culture, solicitors/lawyers... the list can go a long, long way.
I've never used any sites like these, but they wouldn't exist without a large proportion of society allowing/enabling them to. We need to take a long, hard look at where we're heading by allowing everyone to do whatever they want, whenever they want with no consideration of the effects on others.
There are many sites, applications and general behaviour in "the modern world" that I'm including here

You don't like the soapbox, do you?

Soapbox for religion and politics. Sex is very much a Lounge tradition. We're all just a bunch of wild and crazy guys and gals, around here!!

Plus, this is about security, not sex!
