Script is working in wincc server, but not working in client.

In button I have a vb script running to fetch sql table data and paste in excel template. This script is working in wincc server, but not working in client.

What will i do. I'm under heavy pressure from client 😥

Note: This is a multi user project.

Split from WinCC 7.4 SP1 Client Trying To Connect To SQL Server.

do you use SQL windows authentication?

then maybe the user on the client doesn't have the access rights

does client firewall block SQL ports?

I know this is an old post, but for any lost soul searching for an answer to this that the previous replies doesn't make it too clear. What you need to do is on your engineering station(the one that has the configurator or graphics designer ) create a screen that you want to use on the client. Once you've created the screen/pdl, just put a text box and or button in there. Then you want to create a tag in internal tag(just for testing ) and call it TriggerScript or something of that nature. Open up VBS Editor. Switch your "Workplace" tab to Action. Right-Click, then New, then Action. You should see
 Option Explicit 
Function action

End Function

just insert something simple for now like Msgbox "HI"

Option Explicit
Function action
Msgbox "HI"
End Function

Then click Save, You can save the File Name as whatever you want to name it. Then on the Workplace Project tree on the left, you will see the Newly created action populate. Right-Click on the Action you just created and find close to the bottom Info/Trigger and click on it. 
Click on the Trigger tab. 
Click on Tag and then click the button Add
Click on the button with the ... (Elispes)
Find the TriggerScript tag that we created and select it(or whichever tag you want to use)
You will see the triggername shows (yourservername::TriggerScript(tag name))

You can change the Standard Cycle to upon change if you want it to update faster.

Press Okay, Apply, then Okay. 

Now you can simply go back to your screen and click button, go to the object properties window and click the event tab, use mouseclick or whatever you want to use , right click under actio and add a simple vbs command like so :
