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 a voice modem has become a struggle.
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'm trying to use Analog Statistics on a calculated tag. The minimum and maximum values for yesterday are always the same. The calculated tag is combining a low and high register value for flow pulses. You can see the direct reading of the low register tag (2nd pic) shows yesterdays minimum and maximum values correctly. I also attached the calculation tag and expression I used. Why do the statis

I am working on integrating some backend ERP database information into some of the views we have setup. In working to get a query to operate I have a number of where clause items but it appears there is a length limit on the number of characters for the query. Is this configurable and can I make that a longer value? Thanks,
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
Hello,
I've begun using VTScadaLIGHT and I've run into some trouble. I started logging some data and I noticed after a few days that my timestamp is off. Turns out the system's clock was set for the wrong time zone.
I changed it (pacific time to eastern time) and now the Historical Data Viewer is misbehaving...for all tags. When I resume the live view, the far right side is lined u
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

I am in need of help establishing comms to a PLC via the GESRTP driver. I have added a driver to the main area and added children to it as shown in the attached pic. Can anyone tell me what value 26 means in the driver value? If I unplug the PLC the value changes to 2. Also another issue I have is what control do I need to turn on/off bits within the PLC? I have added a toggle switch widget

Trying to monitor Modbus registers in an Accuenergy Acuvim II power meter. Serial comms (RS485 to USB converter) looks to be established to the device at address 2, but no luck in getting values in test tag. Not sure I have the address represented correctly. Device support doc shows the info below. Comms possible? Suggestions?

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

I am trying to conditionally disable alarm so it is only enabled while a certain piece of equipment is operating. I have the built in low alarm configured as such
When I right-click on the displayed analog tag it shows Disable Low Alarm as checked, but the alarm is still active in my alarm history. How do I keep this disabled while not operational?
Thanks.
I am using the warning category for non-critical alarms, and an alarm list widget set to show Active Alarms from the System Alarm DB to display these and critical alarms to the operator.
Currently the warning alarms show up in the alarm list and are highlighted yellow, this is desired.
I would, however, prefer they not cause window flashing or sound, and not require acknowledgement, rath
I want to use an "always high" digital tag sent from VTScada to the PLC as a comms status bit.
I've tried creating a numeric calculation tag and entering the PLC bit address in the address field, but this doesn't work (I'm assuming because the numeric calculation only outputs analog, but correct me if I'm wrong).
I have tried to use a digital tag with start condition, but not sure what
Under "configuration" -> "properties" -> Display Tab, under "Application Window Behavior" I have checked "Resizable Window" and "Constrain Aspect Ratio". The image displays fine on a large screen. When using a laptop screen, however, only the upper left corner of the screen shows, and there are no scroll bars to center the window. How can this be fixed?
Thanks.
I am using a Siemens S7-1200 with VTScada and the Siemens TCP driver. Occasionally, certain tags will be modified fine in VTScada, but they are not written to the PLC program (although they should be). Other times they are changed correctly. It seems to be somewhat random. Would appreciate any advice anyone could give that might be causing this.
Thanks.
Is it possible for VTScada to automatically display a page from the value of a tag?

I configured an ethernet port and CIP driver for a CompactLogix PLC. When I create a new tag of type "I/O and Calculations" the tag browser option does not appear on the Read Address field.
I ran a Driver communications summary report and the % average Quality was 68.8 and average response time is 0.002 which I would assume would mean I am communicating with the PLC.
Any idea why I can't
We are trying to configure a firewall between the primary and the DMZ (Pivot) server. The DMZ (Pivot)server will provide read-only remote access to operators. We are licensed for 25K tags. What is a good estimate for throughput between the primary and dmz server?
Still new to VTScada.
I have an I/O tag of length word in VT scada with an output address to a register in the PLC. I want to set/reset a bit at a desired position in that tag if an alarm status tag is true. What is the best way to do this?
Thanks
I already created the tags for my PLC in VTScada. I am trying to pull the digital status of a device in my system. First I was using Y memory bit, the digital status can be pulled correctly, I can see a value 1 shown on the Tag when that device was on. The Y memory bit address and function code are attached.
Then, I changed the Y memory to C memory bit, the device is still working well.

That TCP server can listen on Defined IP & Port and that can be used to connect with TCP Client.
How can I create TCP server in VTScada?

How can I make disable Automatic Deploy Changes in VTScada.
When I try to deploy changes it says it's not applicable because of enabling automatic deploy changes.
How can I disable this?
Where are those options to disable this?

Hey all,
Just looking for some input on modifying the GE series 90 driver to accept symbolic tags. If this can be managed I can cut out an intermediary OPC client and just run everything through VTScada.
