Basically i have a Total Volume Tag I want to snapshot it into Current Month and Previous Month Calculation Tags on the 1st of the month at 8am.

Volume = 1000
Snap = 500
Cmonth = Volume - Snap

At the rollover time move the Cmonth to the Pmonth
and then move the Volume into the Snap.

Does anyone have any good ideas in how to do this in VTScada?

I have created one IO calculation tag (analog) that shows the value of PUMP RUN TIME in the second.

Ex. Let say I got a tag value as 3600 seconds.
From this tag, I need to show PUMP RUN TIME as in format 01:00:00 (hour:minute:second).

If the value is 3720 I need to show it as 01:02:00 (h:m:s)
If the value is 3750 I need to show it as 01:02:30 (h:m:s)

How can I show that?

I have my DNP3 protocol XML file that includes Digital inputs, Digital outputs, Analog inputs, Analog outputs, Counters, etc.

I need to parse this data to VTScada and I need that VTscada generates tag accordingly.

How can I read the XML file into VTScada and end results that VTScada automatically generates the tags in Tag browser?

How can I do that?

I use graphic editors quite a bit and some features that come in extremely handy that are absent VT Scada would make the work flow more seamless and less tedious in many cases especially when working with multilayer graphics.

• The first I would like to suggest is the ability to lock layers while editing pages or widgets so that they cannot be moved or changed while they are locked. To

Is there any way to rename a type? I can't figure out a way through the application configuration or through export & sync. I have tried exporting and changing the name on the VTS_Reserved tab and deleting the export info and data fields but that didn't seem to work.

Alternatively, is there an easy way to make a copy of a type?

Anyone have any ideas?

Can anyone tell me how to launch what VTScada call the "CIP Address Select tool"?

All I can find in the help is this reference which tells me it exists but there is nothing here about how to open it.

The help says this tool is "... found in every I/O tag that uses the CI

My PLC contains some ASCII text stored within sequential MODBUS registers. How can this be displayed in VTScada?

I've tried both an "I/O and Calculations" tag with a String data type as well as a Legacy "String I/O" tag. No mater how I set these up numbers are displayed instead of text. Also, there is nowhere to put in the range of Modbus registers which hold the numbers which represent th

Finding voice drivers for windows 10 a hassle.

Here's a page of reference conexant drivers you can force windows 10 to use. You'll have to use the Browse my computer, then Let me Pick, then Have Disk, or it will claim the voiceless microsoft driver is newer and therefore better.

I had a issue and was wondering if there were any known issues.

VTSCADA version 12.0.05

I created a Analog Output and a IO Calculation Tag (Only one was active at a time just to make sure it wasnt a tag type issue) to write Seconds to a PLC to verify VTSCADA was communicating to the PLC.

When i logged off my user account both tags would stop writing to the PLC, i added the logged off
Hello. New to this software and trying to get an analog input to read correctly. Maybe this has a simple solution and I'm just missing it.

Basically, I'm reading the analog input register of a MODBUS device which uses a 16-bit unsigned register for its 4-20 mA input. You get a value of 0-65535 with this.

If I read this register with VTScada, it works fine until the 16th bit changes from a

I have been using Push Button widgets with a Siemens S7-1200 and digital I/O tags. I assign the HMI button bit in the PLC to another bit in the PLC and immediately reset the HMI button bit. When pressing the button repeatedly, despite being 1 all of the time, the Siemens controller sees a change from zero to 1 each time.

Now using an OPC-DA connection with an ABB controller, pressing the bu

I'm communicating with an ABB AC800M PLC using the OPC-DA Driver in VTScada. When reading tags, I can increase the "scan rate" in the tag itself, and as long as the OPC server is properly configured, I can get updated values as frequently as I need them.

Pushbuttons on the other hand are "written" to the OPC Server, and there is a 1 second delay at least from pushbutton press to the time the

Hi, in tag browser we can see tag values displayed but they all drop out periodically, with corresponding drop out of information on screens. I'm pretty sure this means that the polling loop is taking too long.

I'd like confirm our strategy for dealing with this:

a. adjust polling intervals on all tags to minimum required.
b. adjust timeout period on our ScadaPACK node, for which all
Hello, we are frustrated about our inability to support our client with updates. They have some IT resource problems and at present the proper ports for remote desktop and VTSCAD server to server interconnect are not open. Our short term workaround is to email them changesets.

But they cannot load them!

The company I work for has an embedded product that runs on linux.

We have a big customer that wants the data from our product to be integrated into their VTScada system. Our data consist of simple booleans, integers, floats, and strings.

As you might guess our management has asked me to investigate the effort it would take to implement.

Where can I start? Can someone point me
