When purchasing Support Plus Renewal, are new license keys generated and must be updated on the machines the original licenses were activated on? Or do the license keys stay the same?

I have some motor data that I want to display on my SCADA screens.

I have tags for various info like Pump HP, Name, Install date, etc.
If I make changes to my app and then import the changeset, all my tag values get reset.

Is there a way to maintain the tag values even through a changeset import?

I'm thinking that importing the information from a text file would work. My problem is

Good Afternoon,

I was trying to install VTScada lite earlier today, and ran into the following message "The program can't start because api-ms-win-downlevel-kernel32-I2-1-0.dll is missing from your computer, try reinstalling the program to fix this problem".

I made sure the computer was current on its windows updates, and tried to reinstall, and I ran into the same issue. The computer is

I'd like to ack an alarm tag when an operator selects a reason (in this case, DowntimeCode, for the alarm to be active.

I've been using \AlarmManager\Ack(MyAlarm); as per the documentation to attempt the ack. This is my first crack at using \AlarmManager\ but I hope to use it a lot.

My testing "AckAlm.src" script is as such:

I have a standard modbus PLC。There are some characters in address 40000,40001,40002,40003,40004。Can I only set address 40000 and address length 5 (from 40000 to 40004) into VTScada "String Data type I/O Tag properties"?How can I do that? Thanks.

With the Alarm Priority Icon Widget, is it possible to assign to different colors to the different alarm priority levels, (Level 1, Level 2, Level 3, Level 4)?

I looked into using a style setting tag, but it seems I'm only able to assign one color for the "alarm state" and can't define alarm colors for each priority level.

Any insight on this would be greatly appreciated.

HI Support,
I have already successfully set up connections to the OPC DA from VTscadaLight. Unfortunately, I have not yet been able to configure a successful connection via OPC UA.
My attempts with a PLC have failed in the same way as with Kepware.
Below I have given my configuration with screenshots.

This non-working page ( ) comes up for me when I search Google for this forum.

Since that page doesn't work is it possible to have it redirect us to ?

Hey everyone, I have a weird issue where if you click on a value (bringing up the trend popup) it brings up every notebook under the parent. I think it happened after I created a trend group but I'm not 100% sure. I have since deleted the group but still, all the notebooks show up.

Has anyone seen this before?

I am trying to open a page in Notepad++ and make edits to the code to change the page when displayed. I have been having a few issues with this.

1) When I edit the .src file and save the code and then open the page in VTScada it does not change. I will close the Idea Studio, close the file folder, or anything else that might have it open that could keep it from updating.

We're familiar with most SCADA software, but still learning VTSCADA. We are used to the flexibility of script to do things that native symbols and widgets do not do.

Right now, we are trying to configure a button that when clicked, will perform:

TagA = TagB. (where TagA and TagB are Analog Values)

Searching through the help files, we can only find "button" style widgets in
When configuring an application and choosing "from a workstation" (via advanced), if I enter a loopback address (eg., or a hostname (via hosts file) that also points to a loopback address, it seems vtscada does not make any attempt to connect to RPC to this address. The use case here is a local proxy server connecting the TCP connection (via port 5780) to a remote VTScada server. Is th
