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?

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.

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.

I have an ultrasonic sensor with range from 40~300 [mm] outputs 4~20 [mA] to my PLC(ClickPLC). I established connection with the PLC and VTScada Light, the value pulled form PLC, is varying from -171 to 700 something with scaling set as 0~100 for both raw and processed.

I tried to pulled data from some other addresses on my PLC which are not used at all, I did get a value of zero. So I assum

since Vt scada has taken by delta electronics,does it support delta dvp 14ss2 rs485 i tried connecting it,or how to link kepserver with vt scada,I am getting data on kepserver quick client but not on vt scada.Seems like some certificate problem.can I get the proper method to do so?

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

I am running the micro800 simulator on Allen Bradley's CCW software. It appears that you support micro800 PLC's using the Symbolic CIP driver, however when I try to use the AB CIP driver demo downloaded from your site, the connection blinks green and does not stay on. I have the simulator running on CCW with a basic start/stop logic. Please let me know if there is something specific that I need t

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.

How can I configure the plot vis

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.

Hi,

I am new to VTScada and experimenting with VTScada light. Did a setup using Pumps and values.

I have a tag let us say > Local TCP Port\PLCSim\Pump 1 \ Motor Speed with current value 500.

Is there any way to set this value to 1000 by using some external programming (Not through manual dials)?

I do see the REST interface provides read capability for these tags, but NOT the w
