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.

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'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

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.

Very simply, we are trying to split an input word into two bytes, hi & lo, but the word byte doesn't appear in functions or expressions or as far as we can determine.

This must be simple to some!

Any suggestions please

Is there a way to remove the Notpad's from the popup HDV.
For Example if each site has a notepad in the Folder it shows all them in the HDV. i am Okay with having the System Notes in there but it is just getting out of control with every other one.

Stop assigning the fourth octet of the PLC's IP address to 1.

That's where the router goes!

And no you can't assign that to the HMI either!
