Shut down Windows HMI PC on contact closure ?

[NetNathan]

In my Intouch systems that are on Win 7, I use a script from the Intouch
"WWTech32" Script Function library... install the script function library files WWTech32.dll and WWTech32.wdf into your InTouch installation directory.

The Command is called "WWShutDownWinNT40".
I run a button script on "Left Key/Up".
But if you can get the UPS signal contact closure to the PLC, you can monitor with an Intouch data change script.

Here is info:

*******
WWShutDownWinNT40 - Shuts down Windows NT 4.0.
Function: Result = WWShutDownWinNT40( ShutDownFlag );
Return value: If an illegal ShutDownFlag is passed the return value will be a -2, if NT security will not allow the current user to shutdown NT or if there is a system error a -1 will be returned.
ShutDownFlag: (Integer) This tells the function how to shut the system down:
1 - Log the current user off NT.
2 - Shut down NT.
3 - Reboot the computer.

Example: This is how to cause Windows NT 4.0 to shutdown:

Result = WWShutDownWinNT40( 2 );

Note The user who is logged into Windows NT must have privileges to shut down or reboot the computer. The Windows NT security allows everyone the ability to log off the system. WWShutDownWinNT40() will force all applications to terminate at the time that the function is called.

Nathan,

That's fantastic ! Thanks for posting it.

One of my colleagues has an InTouch 2014R2 project with a similar requirement, and I'll direct him to your post.

This script function has been around for some time...as you can see, it was for Win NT. It was originally written in 1997 and updated n 1998.
There are a few of script function libraries that some folks are not aware of....Here are all the things inside this library.

There are a few Script Function libraries..
I will start a new thread and list a lot of them.

This is probably what you will need:

https://www.howtogeek.com/109655/how-to-remotely-shut-down-or-restart-windows-pcs/

Based on contact closure, you can send ASCII data from the PLC to the PanelPC using RPC. Not sure how to format the ASCII packet though, as I've never looked into it.

I use Dell XE2 pcs for our SCADA systems.
I was using the XE before it became XE2.
The 1 thing I liked most about the XE was it came with a remote start button input on the front of the PC. That option disappeared on the XE2 for some reason.
You can also still pursue finding the PC start button on the motherboard...as mentioned in another post.
However the choices above may not give you a "clean" shutdown of Indusoft, or any other running apps.

Running the windows script through Indusoft monitoring an plc input link from the Puls will be simpler, which is what you mentioned in your starting post.

what's the problem on 64-bit?
I'm very interested on the crawler solution. Thanks

hi yell
i used the rts/cts signals a few years ago for a project, and havent experienced any problems with 64-bit. I was using Visual Studio with C# to read/write the status of the bits on the RS232 Port.
You can check/set manually the bits from a lot of terminal programs, for example "hercules rs232".
