VTScada should work with any standard voice modem. Though we cannot guarantee the compatibility of third-party modems across all Windows operating systems, our engineers have provided the following comments on modems that they have used or have been used by our customers.

We provide this list simply as a place to start when researching modems. We have no relationship with these manufacturers

Hello, I am trying to connect mysql database to VTScada application.
First of all, is it possible to save to database values from plc through VTScada?
I want to save temperatures through time.

If yes, I haven't manage it yet. I have created a Realm and added my current application to the realm.
I created a VTS ODBC connection at System DSN. I test the connection and obviously it retu

I have a large mobile treatment facility that has not been operated in 4 or 5 years. I just recently refurbished the entire set up and went to launch the scada computer only to find out it is completely shot. I have an old back up of the scada folder but it does not tell me what SCADA program was used to develop. I am hoping that I can utilize VT Scada to import the old programming but have no id

Hello, I use VTScada Free and try to communicate with Micro 820 through CIP protocol.
I downloaded your sample, and can see that it connects to plc.

But I can't figure out how can I pass my tags.
CCW understands tags as variables. I must give a variable name and then use it.

VTScada asks for address.
I tried to pass the names I have given to variables but, no luck.

Thank you

I am trying to communicate with an SNMP-enabled Ethernet switch. I added a Driver which is connected to a UDP Port, which requires a local and remote port #. Should it be 161 for both? I have imported the MIB file and created a tag, but the driver is not communicating.

This is one of those distinctions that is easy for us to take for granted because we work with VTScada every day. It came up a few times at the ACE 2017 conference in Philadelphia.

VTScada Thick Client Licenses are each installed on individual Windows computers. Every VTScada application needs at least one installed Thick Client license. A separate license is required for each PC that has VTS
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.

This is also a great
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
This is a recent question to our support team:
I received a pop-up warning when trying to start VTScada. When I click OK, it starts the VTScada Application Manager (VAM). This is the warning. "The performance counter registry hive is corrupted. Some WorkstationStatus functions may not work. Click OK for next warning or Cancel to clear all warnings." Is there anything I need to worry about goin

Sync'ing the clock on a PLC with the VTSCada computer time comes up fairly often. Depending on the requirements of the PLC, there are a number of ways to do this. The easiest way for all of them require using a trigger tag in the VTScada application that will trigger at a known time. For now, call this TriggerTimeSync and set an On schedule for 01:01 am and off 2 seconds later with no off schedul
Hi all,

I am working on my first VTScada application. I am trying to set up the internet client and I am not using an SSL certificate. I have already created a realm. I am trying to set up the server now. I cannot get my 'server list' to stay populated. I click 'add' and I have tried adding the IP address of the computer that will be running VTS and that same computer's name. They will add t

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

Answer - A small portion of application settings require the app to be restarted when they are changed, though most do not. Compiling some types of custom code will require an app restart as well, though this does not apply to pages, graphics and tag types.

Answer - Yes, you will need one license per server. This can be a Runtime license or a Development Runtime license.

Note that free VTScadaLIGHT licenses can be redundant servers to one another but NOT to standard paid VTScada licenses.

More on VTScada redundancy can be found here:

Answer - There are several ways to export data from the VTScada Historical Database.
