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

But they cannot load them!

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.

I've created a Custom Type that contains five analog tags - Value, EU_Max, EU_Min, L_Alarm, H_Alarm. Their PLC addresses are based on a custom Parameter called 'BaseAddress'. Address expression example:
\baseaddress + ".Value"
I've also tried:
Pickvalid(Concat(..\baseaddress, ".Value), "")
and
Concat(getphrase(..\baseaddress), ".Value")
etc
Have also tried checking and unchecking

Someone redefined a type with a bunch of tags that didn't actually belong to the Type but were meant only for a particular instance. This went unnoticed for several months.
If possible, I'd like to set the Type back to the way it is supposed to be but cannot lose the history of those tags that were inadvertently added to the Type.
Hope this makes sense. Is there a not-too-complicated way
We are testing the VT Scada Light. I am trying to connect it with a energy measurement system using Modbus over TCP/IP directly from PC.
I created the tag using 'TCP IP Port' -> 'Modbus Compatible Device' -> 'Analog Input' and didn´t get the communication.
Followed the basic configuration done:
TCP IP Port: Adress: 192.168.1.12 Port: 502

Hello,
I recently downloaded VTScadaLIGHT in order to test a prototype device. I am writing to Modbus registers 40001 - 40010, and splitting my floating point values into 16 bit unsigned integers. How would I union them back together in VTScadaLIGHT as a floating point value?
ex)
40001 = 16 bit unsigned int
40002 = 16 bit unsigned int
union of 4001 and 40002 = Floating point

If I open the Historical Data Viewer page and turn a tag's trend visibility off by clicking the eyeball icon and then close the page, the trend visibility is set to disabled globally. You go to a page showing that tag's value and click on it to open the plot and it is not visible. Not only that, but any other user will also have that tag's plot not be visible.

Hello, I am new to VTScada. I have an Alarm Word from the PLC, where each bit represents an individual fault. I'd like to read the entire Alarm Word as a single tag in VTscada and create alarms for each individual bit. I have found the expression Bit([HMI Alarm Word],2) for example to work as an expression, but I'm not sure where/how to enter this to create the Alarm. Thanks.
