The VTScada help file indicates that the RadioButtons function should be called using the Dot notation:

\System.RadioButtons(.....);
When I attempted this implementation the radio buttons did not show up in my display. After verifying my variables I tried using the "\" notation:

\System\RadioButtons(......);
This worked.

(Full Disclosure: I'm using the VT11 era "CompletedTutorial" ap

Is there a way to resize the horizontal buttons widget for a selector switch tag? It seems like it would be standard practice to have some user set-able parameters in the properties dialog for setting the width and height of the buttons, but there is not and the buttons are just too small.

Does VT have the ability to publish data to an MQTT broker?

Do you have a timeline to implement Client Drivers for MQTT and OPC UA?

Not that I really want to use MQTT but these two look like the future of interoperability between PLC platforms, serial servers, and older oddball devices.

UPDATED ANSWER - YES! In addition to OPC DA, VTScada now supports OPC UA Clients in VTScada 12. See post below.

I want to write an expression on "digital status" tag. According to changing in value of digital status tag, different text should be shown.
As like, If digital status tag value is 0 then it should shows 'disabled', If its value is 1 then it shows 'running', if tag value is 2 then it shows 'blocked', if the value is 3 then it shows 'unknown'.

Looking for the best way to configure resolutions between 10 pack applications and various client size displays. We have 15" 1024x768 HMIs at our panels, these using the 10 packs so we can filter by panel number. Then we have 27" and 32" monitors in our operator room running the main application on the VIC, and then programmer staff use 24" monitors.

Here is a look at how we have one of the

The High Performance HMI Handbook (Scada Bible) suggests that Faceplates should have a reserved spot on displays that change according to the item selected on the display.


Everything on the screen is selectable, and when selected the standard faceplate for the element appears in a reserved “faceplate zone” rather than floating around the screen obscuring the graphic.

Good morning,

Little quirk I noticed this morning - When using the Vertical Analog Bar High Performance Widget (VT12) the setpoint only allows you to choose a tag. It should allow the selection of a parameter, linked tag property or expression.

In my particular case I wanted to select a linked tag. This was accomplished by just choosing the tag (that I would like to have linked too) and t

I believe I know the answer to this but figured I'd ask anyways. Is it possible to do a lookup table in VTSCADA?

I have a customer that wants some live calculations done that are currently done in an Excel spreadsheet, some of which involves a lookup table.

Even if I have to do something external and pass the result back into VTSCADA. Can VTSCADA read from an Excel spreadsheet through scr

I am looking for some direction on creating a Data Grid in VTSCADA
that can poll from the historian.
There is an example in the Oil & Gas Suite for the flow computer history.


Any help would be appreciated

Is it possible to run two applications at the same time on the same PC? I have two apps that are at the 50 tag limit and I get errors when trying to run both apps. Is this a limitation and am I limited to just one app? Thanks

I have a device that sends status updates on a Modbus network. I have successfully connected to it and can access the registers. However, there is a status register that stores the system status as an integer that I need to decode into a binary word. I then need to be able to access each bit of the word to determine the system status. How can I accomplish this? I'm new to working with SCADA and t

I have some data points that I need to put in a report, but I only need to show those values every 15 minutes that the process is in a certain step (A pump is running). The report will be ran at the end of the month and will cover the entire month.

I would prefer to have those points logged continuously for trending and so the customer can look back at any time and see what the value was whet

We currently are looking for a possible way to compile all the exported data that is collected into a nice easy to read template, keeping it as user friendly of a process as possible. I myself am very new to VTScada so I thought this would be the best place to come, has anyone found any cool solutions to this issue at all? These are all water treatment facilities so they're primarily use X amount

The secret is that temp is at 30002 and Humidity is at 30003.

The lack of documentation just said that Temp was at 1 and Humidity at 2 and the fun part is any call to an invalid address kill them all.
