Has anyone experienced issues being online with an Allen Bradley PLC, causing VTScada to slow down or even lose communication at all? Doesn’t really cause any major issues (yet) but I’m curious if anyone else has seen this, thank you

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'.

I want to write an expresion in tags. How can i

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.

When my level goes above to start level it will start my pumps & when level reaches below to stop level it will stop tye pumps.

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

We are preparing to upgrade our software from 11.3 to 12.0+ and I am looking for any information that we need to know before upgrading? (i.e. are there any windows updates that don't play nice with VTScada v12?, any major changes we should prepare for going from 11.3 to 12?)

Also, as a secondary question, is it possible to launch our application on a different PC/Server and run it as if it we

What is the best/easiest way to manually disable comms to a device that is missing? I have devices that are offline at times and I want to optimize comms by preventing the driver from trying to constantly attempt comms to a device that I know is offline. Is there a setting I can toggle? Thanks.

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

We have 4 computers on the same network at a single location, none of them have internet access and the times on the computers will tend to float away from each other. Is there a way to sync all 4 using VTScada somehow? Basically just need to have one common time across all stations if possible.

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

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?

Hi community, is there a way to clear the logged trend plot line data. I want to keep storage on the host pc to a minimum and do not want this file to get too large. Keeping data for a long time is not a priority so I would like to delete the logged data periodically. Thank you.

Hi community. I am trying to use a calculation tag to determine the bit status of an analog value. I cannot seem to get the syntax correct to put in the expression. I found the code snippet below but I think that may be for scripting not expressions...not sure Is there any documentation on functions and syntax for these expressions? trying [value] && 4 does not work to find the statu

Hello vt scada community. New user here. I am looking for assistance to create several digital tags based off the value of a single Modbus register. For example, register 40001 value =1 is "pump running". Same register 40001 value =2 is "pump stopped". How can I accomplish this with minimal tag usage? Thank you

I need to create a report that will display the lowest value that a tag registered throughout an entire day, along with the time that occurred. On top of that I need to display this information for the entire month.

I really do not know how to approach this at the moment.

I thought about using the standard report type since I believe it dumps all the available data into the report, and th

Is it possible to build a tag that can determine the elevation of my facility based upon the coordinantes in the parent site tag?

Or is it possible build a widget that references the Long. and Lat. of the parent site tag to determine site's elevation?

Thanks in advance!

Programming question:

I'm using an Analog output (VTS Datatype) writing to a PLC DINT by way of a "Numeric Input" on the page to allow user to enter a passcode (EQU in PLC) to permit the action of a selector switch, right below the numeric input box.

When you enter the correct number, "it is retained in the VTS tag browser" and will work okay. But I need a way to clear it out after a minu

It appears as though you cannot pass a Universal IO - String Calculation tag configured as a string to a Script tag.

Changing the Universal tag to a Numeric Calculation, but keeping the value as a string, works just fine, the Script is able to use the parameter's string value. Downside of this is that the value of the tag does not show in the tag browser.

As well, using the legacy Calcula

I have a 4 position switch in the PLC
I need a 4 position switch to write to the PLC from Trihedral ver 12
so that it is not maintained and will match the one in the PLC

I assume I need a widget to provide an analog out to write a analog value to the PLC but I am not sure how to do it.

Can anyone help me here?
