Hi,
I'm a new user of VTScada and currently installed a VT light version. I want to setup Enron Modbus Communication with a RTU to read historical archive of the device. I need Technical support to setup a Enron connection in VTSCADA and how to read historical data and how to trace the communication to verify Enron query and responses?

Hello,
I am setting up an integration between VTSCADALight and the Azure Event Grid MQTT Broker. I have provisioned a certificate and an Event Grid namespace, and demonstrated using MQTTX that I am able to connect with the certificate from my host to the Event Grid's MQTT Broker and send messages. Doing so requires specifying mqtts:// as the protocol, 8883 as the port, and using the SAN value
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
I need a safe way to stop multiple VTScada applications unattended and the VTScada Application Manager (VAM) on a monthly schedule to allow OS updates and a full system backup without risking application damage. Applications are already set to start upon system startup.

For a new application i need to connect VTScada with a MS-SQL database. I create a project with VTScada and i connected with a MS-SQL Database, i check the communication and all is perfect. I can write digital, analog and discrete data types tags from VTScada to MS-SQL Database. The problem i face is that i can't write string data type tag, e.g a name. Could you help me?
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
I want to animate a pie. My plan is to stack a white circle, then a yellow pie for power, then a small white pie, and another small colored pie on top of that so I can see how the generator speed is layered on top of the power output.
However, I don't see how to bind these things to the pie shape.
Or is there a way to color the arc meters in the gauges?
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 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.

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

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

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?

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.
