This question recently came to the Contact Us form on our website and we realized that we were not doing enough to explain this unique and important feature.

So Dave Spencer created this video to explain VTScada ChangeSet files. ChangeSets are the preferred distribution and update method when the development computer and customer computer are not on the same network.

I upgraded a small test system from VTScada Lite 11.2.25 to 11.2.29 and noticed the Anywhere client no longer functions. However the VIC and MIC all still function properly.

This test system is installed on Windows 10 x64 and has all applicable windows updates installed. I uninstalled 11.2.29 and re-installed 11.2.25 and the Anywhere client functions as it should.

Each new version of VTScada introduces new tools and sometimes changes how older features work. Your VTScada license entitles you to upgrades for a period of time after purchase. (Maintaining a Support Plus contract provides unlimited upgrades.) You can find the end date of your paid upgrade period in the About dialog, accessible from the VTScada Application Manager.

Please review

For now, call this TriggerTimeSync and set an On schedule for 01:01 am and off 2 seconds later with no off schedul

Tank cut-away images are designed to work with the Color Fill widget. Place a cut-away on a tank and then set the color of that cut-away to something that will be unique on the page. Orange is a great choice. Now, place a Color Fill widget on top of the cut-away and set its Changed Color to match the color of the cut-away.
The Color Fill will be visible only where it overlaps the matching co

Does VTScadaLIGHT support the Anywhere Internet Client?

The mobile client seems to work fine in a browser, but when I log into the AIC throw a web browser all I see is a white page. A logon failed notification gets logged to the System Event DB even though I know I'm using the correct credentials.

Afternoon All;
I am trying to poll a Modbus flow meter. The register I am polling is a floating point, and at this time just looking to get a proper HEX response. Below is a couple of request and response.
