Hello everyone,
I'm playing with VT-Scada, and I encountered a problem I didn't find any solution.
I searched in the documentation but I found no answers.
I wish to plot measured data from different (but consistent) inputs in a single graph, each one with a different colour.
Is it possible to do so? If yes, can anyone tell me how?
Thanks a lot,

First I installed 90 day demo version in my laptop. I developed the project in that demo version. I purchased the Developemnt License key.

So, I deactivated the demo version. Now I am trying to activate it again using the licensed key(25 Chaaracter). But it is only giving option to enter 16 digit key.

Suggest how to activate it + I also want to use my existing changeset file developed on

I have some string data internal to my Siemens S7 PLC that I want to display. When I use the string tag type all I get is the number value of the data block.

Is there a way to easily display as ASCII?
Also how to display the whole string, my string data is assigned 6 bytes in my PLC, but the maximum VTSCADA allows is 4 bytes, one double word?

For example my string is located

Hi All,

New to VTScada and evaluating the light version for our manufacturing plant.

I want to display different text (strings) based upon a tag value from our siemens plc, I am getting different values through but can't work out to conditionally call different texts based upon this value.

So for example if tag Part number == 1, display SK90
if Part number == 2, display SK110.

Can someone tell me where to find the "Web Browser Widget"? The help says it is located in the "Tools\Web Browser Tools" folder but that folder does not exist in my version of VTScada. Is this an add on that needs to be imported or something?

We're currently sending our customer's VTScada e-mail alarms through a dreamhost mailserver but need to switch that to our customer's Microsoft365 mailserver with OAuth 2.0.

Their ISP has given us all the credentials we need. All that's missing is our redirect URI & certificate.

Is there anyone here who can baby step us through those steps? I've been reading & re-reading the V
I want use JSON/XML Driver in VTScada A to read a tag from VTScada B.

The VTScada B has configured the corresponding parts. So I can get tag1 data in browser with URL " timestamp,'MyTest\Machine1\CommDriver\Tag1:value' from history ORDER BY Timestamp DESC limit 5" from VTScada B.

The data is as below:

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 ?
