I have only one VTScada. I want to regular move the earliest month history data to another disk driver for efficiency and data backup. How can VTScada do this? Thank you.

Is there a way to make a Alarm Acknowledge button that will Ack all the alarms in VTScada and send the Ack command to the PLC?

Currently we have layered the PLC Ack command button (momentary button) behind the build-in Acknowlegde All button, and we need to press it twice to Ack alarms in VTScada and in the PLC. Looking for a way to combine it in one button.

Please provide an example of how *this is done.

May be set in a parent context tag if you have Modbus devices with differing address offsets.

I have no idea how to put a context tag into an application's configuration.

This help page describes thin client licensing as follows.

If you have a multi-server application and want to allow connections to more than just one server, each must be licensed to allow client connections.

This help page describes thin client licensing as follows.

It is common for one of your server keys to allow many thin client connections and the others to have few or none.

I built a Lufkin SAMS controller inside of my VTScada and it automatically built all the TAG's as either Analog Status or Digital Status TAG's (Legacy TAG's) I am trying to set the lowlow / low / high / highhigh limits for the Analog Status points but I found that these types only allow for a Low/High alarm, but in the support document the picture used for this TAG is the Calculations I/O Analog

Hey guys,

We have a decently large application (80k tags) with lots of Flow Computers. We have Low Flow setpoints and Debounce timers settable by operations and just go the Alarm tab on each Analog Status (FC still uses old style tags).

One issue we've noticed is if you change the parent tag type, or have a hard shutdown due to server issues, all these values get wiped out and get set to

I am trying to test the REST Queries .

I have set the application property "RESTAllowedOrigins" to null as given in your example HTML page.

I get TypeError failed to Fetch at the bottom of the page (in Red colour)

Anyone has experience with this REST API Queries?

Any more tips, examples etc?

I would like to use the selector switch tag type as it has built in feedback alarms and the switch widgets. However, the components I am using will pulse the command to its state. Another reading will verify that the command worked and that the component is in the commanded state. I don't see an option to pulse the output of the selector switch. Will I have to use the digital IO tag and a cou
I tried to setup Thin Client access to the VAM according to the online help but got stuck at this step.

I couldn't find a "Thin Client privilege" to add to my account but adding "Internet Client Access" seems to work.

Parent Child References are the easiest to map. However, I am exploring the possibility that the hierarchy for an application might require references to properties in an adjacent tag in the hierarchy. I haven't run into issues when concatenating descriptions in this way. However, in other values that require a specific data type (Scan Intervals, Drivers, AIO Scale Min's and Max's), I have exp

Would anyone happen to know a way I could have a button do 2 different things on a single press? Like set values to 2 different tags or set a value and change screens?

i haw installed VTscada 12.1.12 and trying to add a OPC UA Client driver in my tag Browser. but when i selecting this type, the program closes.

is the VTScada light supporting OPC UA Client Driver?

Has anyone found a way to print a full help topic from VTScada's online help? The only workaround I could find is selecting all the text, then copy pasting. If anyone's got something better I'd be excited to learn from you. is not the only website with this issue.

I was hoping to take an existing VTScada application which has been running for 6 months and create a duplicate copy of the application & its data to run side-by-side on the same PC.

Can this be done? I thought I'd use the "Get from ChangeSet" option but the Wizard doesn't let me rename. The "Clone from ChangeSet" option does however clones don't contain data. Is there a way to copy th
Hi folks, having problems with the reporting tag, and the time duration for this. I would like the duration to match a calculation tag. I am using the tag as a reference in the parameter for the Report Duration as shown in the screenshot below.

However, it does not act as I would expect… and I have had to create multiple report tags to get around it in the short term… however t

I have been trying to set up a connection between VTScadaLite and a Allen Bradley plc using Ethernet/Ip. From what I can gather I am using the correct driver and tag set up. But the digital [IN] does not register a value coming from the PLC.

The PLC can be pinged and ports have been enabled with all firewalls turned off.

The running PLC program is being monitored using the CCW s

In June of 2022, Microsoft released an update which by default harden DCOM connectivity to OPCDA and OPCHDA servers. I am aware that this can be disabled, but that option will no longer function in March of 2023.
Does the latest version of VT SCADA support the new DCOM Hardening for remote OPC DA Connections to the VT SCADA Real Time server?

I'm currently building an alarm annunciator for speech to text alarms spread out over multiple areas and where there may be multiple alarms active at the same time. I was wondering if there was an option, or if it can be done through scripting, to replay the list of unacknowledged alarms after a set time out and then repeat the cycle until all the alarms have been acknowledged.
