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

This one came in by email but I thought it was worth adding -

I have a couple of different machines running the same application that need to start up with different pages. Is there a way to do this?

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

Q: I just updated to a newer version of VTScada and now my modems no longer work!

A: Customers using the modem dialer feature of the Alarm Notification System must ensure that they apply Windows updates on a regular basis. Updates to VTScada will often include modem drivers that have been patched to work with the latest Microsoft updat

Is there a way to read a 32 bit modbus value directly into a 32 bit value in VTSCADA? This way we will not need to read a 32 bit value as 2 single 16 bit values and then combine it.

As of 2017-02-10, only the following tag types count against your license:

AnalogControl
AnalogInput
AnalogOutput
AnalogStatus
DigitalControl
DigitalInput
DigitalOutput
DigitalStatus
Pump
RateOfChangeTag
SelectorSwitch
StringIO

The licensed tag count is the sum of all licensed tags in running VTScada applications.

Question: I have a set of oil batteries, each of which has a standard set of values representing the pump and tank information. I would like to represent this information in a summary table with one row of data for each battery. We area adding new batteries on an ongoing bases and would like the table to be automatically updated with data from these new batteries.

Question from a customer - i.e. Site1 has 2 booster pumps and site2 only has 1, however my tree has the possibility for handling up to 4. Would disabling the two unused booster pumps tags in these instances count towards the used tag count?

Here is a question I fielded recently:

"How can we prevent SCADA operators from accessing the Windows® Operation System of a PC running a VTScada application?"

Can one push data to REST APIs provided by cloud based machine learning/big data analytics platforms? Do you provide a REST API so one can push to your system. I am currently using http://infiniteautomation.com/ and combination of MEAN (MangoDB, Express, AngularJS, NodeJS based solution to capture low throughput data from battery operated devices on a mesh network.

If I need to have multiple devices in one single app, would each Comm port be a separate device? I am asking about "Realms."

Question submitted by a VTScada Certified Solution Provider

While discussing some remote access solutions, a question arose about how VTSCADA handles version differences. The specific example we were discussing dealt with an integrator remotely logging into a network and then making changes to an application hosted on a remote machine using the integrator laptop, and then pushing those chang

What is the relation between the real I/O and tags? Are they the same?

The VTScada graphics library is located in VTScada\VTS\Bitmaps. The use of the term Bitmaps is a holdover from many years ago and no longer represents the actual makeup of the graphics library, which includes approximately 3000 WMF (vector), 1000 BMP (nonvector), 4600 PNG (nonvector) and 3000 SVG (vector). Some of these files are in more than one format. The development team noted this is because

Yesterday, a customer asked the best way to create a reusable set of bitwise reads for a packed PLC integer register. This is best done by creating a tag structure with a Context Tag as the parent. Create a parameter for the Context Tag called something like "BaseRegister" but leave it's value blank. Create the preferred Digital Status tags for each bitwise read as its children and set the Addres
