As the help page I can read tag value by REST.

Can I write a new value to a tag with the same way? Maybe it likes https://Your.ServerName.com/RealmName/REST/SQLQuery?query=UPDATE tablename ....

Thanks.

I would like to transfer 25 or so pages from one application to another. Is there simple way to do this?

I insert a webpage into VTScada page by ActiveX(300, 150, 400, 200, "Shell.Explorer" ). I can see the webpage content in VIC URL Mode.

But in MIC URL and Anywhere URL it dosn`t work. I see nothing. Why is that? How can I improve that? Thanks.

My first post to this forum!

I have set up a DNP3 driver and configured a Digital tag. My outstation device is set up to provide a binary tag w/ packed format. However, I am not able to get a response from the index=1 tag on my VTScada Application Dashboard.

Has anyone successfully setup a DNP3 binary tag (w/ "packed" format) in VT Scada?

Any input would be MUCH appreciated.

Is OPC UA Driver supported in Light Version? I cannot get it to connect to a server: status not refreshed.

On the I/O address assist button seems grayed out and I cannot tell what is failing.

Tried from same client host UAExplorer and it connects fine.

I selected Anonymous and no certificates. Is this configuration not supported?

Is the a log file somewhere I can view?

Hi,

The OPC-UA specifications define a Method NodeClass: https://reference.opcfoundation.org/v104/Core/docs/Part3/5.7/

A method defines a callable function which can be invoked using the Call Service mechanism defined here: https://reference.opcfoundation.org/v104/Core/docs/Part4/

In practice this means I can implement a method in my OPC-UA server and invoke it from an OPC-UA client o

New to VTScada and in a new employer who has a device with VTScada (unsure lite or not) that will now not start. Embedded Win7 and the loading splash screen starts for a few seconds then goes away without any error or remark.

Have tried debugging the issue the past day by viewing forums, manuals, etc but not finding anything.

Biggest issue is I'm not sure they have the knowledge themselv

Question posed on our website: Any work on supporting/offering OPC UA? MQTT? I like the internet server & redundancy. What I may want to do is integrate your product to display VTScada HMI screens. How do I populate the screen(s) with real time data? I have in place all the data acquisition & can provide it to your internet server(s) via??? I'm thinking in terms of Opto 22 HMI servers wh

I am working on some software for my company. Field technicians can enter well pump readings and the chlorine residual through an Android / iOS app.

The backend of the app is written in Node.js.

I'm trying to get the pump reading from VTSCADA and send it to our app.

I wrote an API (documented here )

I also wrote a CLI (documented here )

Is there some way we can take the pump r

So trying to read values out of an INT table from a PLC5. The positive values all read fine but if we try to read a negative integer value we get the wrong data in VT, usually a value of 6553. To get around this we just did a MOV from INT to a FLT and it reads fine again.

What would be the limitation of reading negative integer values?

The VTScada Red Bell can be turned off on the server, but the VIC clients and Anywhere Clients are still showing it. How do you get the same behavior out of the clients that you do from the server?

I turned off "Show Alarm Indicators" in the application configuration / Title Bar Contents. And it is gone from the Server but not the clients.

Any help would be greatly appreciated!

I created an additional Alarms Page using an Alarm List widget, and it allows me to filter the System Event DB out, but that pesky Alarm Icon at the Title Bar is glowing and offers to take a User straight to the Original Alarms Page where they have access to see all of the System Events.

Any way to stop that on one front or the other?

I have even used SecurityCheck to give Developers visi

I'm just testing some comms on the bench here for a customer. I can set up the DF1 tags fine and get good comms and data when set to TCP/IP, but when I try to switch it over to the serial comms I get an error code 16 Illegal Command or Format. I can see on my SerialPort tag I don't have any errors so it must be something in my DF1 driver tag I'm missing.

Thanks!

Need to send an alarm acknowledgement over MQTT, is there a way that I can read the status of an alarm to send; or can I look at the canned ack button and send after that has been pressed? I just need something to trigger a write message.

What IP cameras are supported and can VTscada support PTZ on any of them.

I am using VtScada-Light and have a few days of data stored.
Everything works great - it is a really nice product.

How can I move the Historical Database to a different larger drive?

Thank you

When using a Zoom modem for alarm dial-out, I am getting a SAPI Error: 0x8004530A when attempting to call out. I have downloaded the correct driver from Zoom, checked the registry settings, set my area code and run the diagnostics on the modem (every was normal). Any thoughts?

Solved - We had the modem installed on a rack mount server running Server 2019 with no sound card.
