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
Dear Community,
I have micrologix 1100 PLC and VT SCADA Light Version. I had communicated both SCADA and PLC. Now, I want to send logs over UDP protocol to the syslog server. i need help and step by step guidance about this.
Secondly, I want to know where VT SCADA light version stores the logs on the PC and how I can enable VT SCADA to save the logs at specific path.
Need your help pleas
I am connecting to the network for the first time in order to build a demonstration model to present as VTSCADA's suitability for our new SCADA system and I am having an issue with connectivity which I did not face with Ignition.
I am attempting to connect to a Micrologix 1400 plc, my server is set as my laptop, in the TCP/IP Port page I have entered the network IP address and TCP/IP Port num

I need to average one point on the graph to another, without exporting all the recorded content, only the selectable content. And I need to export it via Excel. How do I do this? Is there a method?
I need to average just this one pen that is circled:

I have a device that receives information from a sensor. The sensor information is displayed on a graph. At certain points on this device, the variable becomes negative and resets to zero. How can I exclude this negative and reset variable from the graphs so that it doesn't apply to the invoice, since it makes no difference and will end up interfering with Excel exports?

In our project, we would like to use to connect VTScada to SAM (Sigma Air Manager - Air compressor management system) module with Ethernet IP communication.
In help guide, I don't find Ethernet IP communication details and not found driver also.
Could you please advise how to set up Ethernet IP communication in VTScada?
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

why dose a module appear multiple times? What do the subsequent numbers represent?
I'm currently lining up hardware to experiment with VTSCADA. I'll be using an Arduino Nano for the Control and looking to communicate with VTSCADA.
Can I use the RS-232 protocol or would it be advisable to use RS-485?
The answer will provide me with a direction on the communication interface hardware.
Kind Regards - Aaron
I would like to activate a tag in the PLC for 2 seconds and then have it deactivate automatically after pressing a button. Could anyone guide me on how to achieve this?

Some historical data of the labels cannot be retrieved.
The "Enable Record" option indicates the enabled state.
Is it possible to create multiple I/O servers with different polling cycle with offsets to avoid request/polling cycles from two I/O servers overlapping?

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 an application where my client no longer has username and password access. How can I force access? Or can I obtain new access without having to rebuild the application?

Good afternoon, I am looking to be able to make a query to VTScada using a DSN connection and return a list of all the active alarms in a vtscada application. Maybe with the ability to filter by area. Currently I can query tag data/values with great success.
For example, one query I have setup is the number of active alarms at a site. I do this by creating a calculation tag for a site (context

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?
VTScada does not support connect to Omron PLC with eth/ip protocol?
I thought it doesnt matter what is the plc I have using, if that have this protocol. I try compactlogix, controllogix, etc. (symbolic adrr.), but nothings happened. Ple
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.

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

In help guide, it mentioned like this,

The selected application could not be converted to the current version of VTScada. The application will not be modified.

Hello.
I am trying to write 4 separate analog values to 4 separate 16 bit registers in a GE relay following a user hitting a button on a dashboard. It is to drive virtual inputs which will toggle a contact output. Wondering what the best way to do this is.

Could you tell me if VTScada can reliably monitor 250+ SNMP agents with 150 points per agent, and what are the key system resources or configurations that impact that performance?
So I'm a bit out of my element here- we're moving to VTScada and I need to get all of our existing tags and alarms added to this new system.
As it stands, all I have to work with is the PLC's IP address, port number, unit ID, and a whole lot of named datapoints and alarms with modbus addresses. This has seemed like more than enough, but I'm seeing a LOT of options here and I'm clueless on wha

So ripped this up to try to auto generate page menu's as a test.
is there no way to endcode the parameter into the MenuItemTag,
there is teh Decode of course but why is there no Encode?
Am i missing something?
Tried passing the Parameters multiple ways Unique, ParameterSet, root, name.
But it does seem to have no easy way to do this is it locked out for some reason?
