I've connected to a local OPC UA, can browse the nodes and have imported a tag. In the tag properties, if I select the tag helper OPCUA button, it shows the current value of the variable.

My problem is it doesn't show the value either in the tag list, or when drawing the tag.


I'm afraid I've missed something, but I just can't find it.

Thanks in advance

In one of our project, we want to move our VTScads project from one PC to another without losing all the data and validate license.

If I want to move, what are proper ways or suggested steps?

I know how to deactivate and activate license when we move from one PC to another. I would like to know about other steps that we need to take care of. Thanks.

This warning pops up several times every month.

I'm needing to do an HTTP POST to a web server from VT Scada, which will reply with a JSON response.
From what I can see, the JSON/XML driver is read only, not write. I.e., can do an HTTP GET, rather than a POST.

I see there is a function called HTTPClient.HTTPSend(). How would I be able to use this function so that it operates in a similar way to the JSON/XML Driver?

Has anyone done

As I understand, calculation tags do not count towards license..But what if we put manual data in it? Will it count towards license?

And if we use it in script, will it count towards license?

Our SCADA is pulling analog I/O from a InSiteIG instrument for dissolved oxygen and total suspended solids. It is pulling modbus addresses; for example, register 30005 would be the sensor value for D.O. sensor 1. I am looking to improve on the basics of what has already been designed by using the I/O & Calculations, Analog (Calculation box ticked). I'm having somewhat of a difficult time in c

I have created small popup pages for controlling pumps and gate valves, etc. In the Application Configuration Display Properties, I have turned off all Title Bar and Task Bar decorations for popup pages. This works and looks as expected on the server, but in the thin client, all the decorations are present, seriously distorting the page appearance. Is there a way to turn them off in the thin clie

Hi! I have Omron CJ2H and I've trying connect VTScada to PLC Omron via Rockwell driver as Ethernet/IP protocol, but nothing worked. What am I doing wrong?

Unter TwinCat 3 (Codesys) arbeiten wir mit OOP. Dabei nutzen wir unter anderem Methoden und Eigenschaften (auch Schnittstellen). Nun möchten wir die damit aufgebauten Bausteine über OPC UA nutzen. Dies funktioniert soweit, jdoch stellt sich die Frage, wie ich eine Methode unter VTScada auslösen kann? Wie müssen wir vorgehen, damit wir über die Visualisierung eine Methode

Ok, so I have a mqtt broker publishing to vt scada, and vt scada doesnt like it for some reason. It gives me a flat line for a graph every time the value updates in historical data viewer. It also seems to update values from all time to the most recent value given. For exampe, i have a current value with max min and average set at 26. Then mqtt publishes to vt scada the value of 25. All values th

May I know how to resolve it step by step?

Hello.

For forcing Virtual Inputs, a message with 4 indivisible records must be written
