Hi,
What Windows version do you use?

You should open incoming connections on TCP port 80.
To check, just open http://yourIP/ from another PC. You should see IIS welcome page.

OK, be free to ask 🙂

Hi,

Polling is slow, because the device doesn’t respond for “State” requests. Deactivate such requests in the template editor (keep “Temperature” active only) and compare the speed.

Scheme Editor were changed. There is the old version in the video. Please create a new topic if it doesn’t work. editor.html must be open in a web browser not Word.

Hi,
Thank you.
The expected behavior in this case: values and statuses of tags are zero when connection is broken. Does it work as expected or not?

“Unable to request because connection is not established” – probably, the device disconnects from the PC. If this is a usual LAN, you should check communication with Modbus Simulator installed on another PC. If it works normal, the problem is in the device.

Hi Marko,
Nobody has purchased the development of this module yet. You can be the first 🙂

Add to the Formulas table:

double Beat()
{
  return (DateTime.Now.Seconds % 10) < 5 ? 0 : 1;
}

Then use in the channel: Beat()

For example, when we got similar error with Inneasoft BACnet OPC server, I wrote to the developer and he implemented all the required methods according to the OPC specification to make the OPC server works with the libraries that are used by Rapid SCADA.
We can try the same approach.
Rapid SCADA uses the official libraries by OPC Foundation. Unfortunately, they are capricious. I hope the future is cross-platform OPC UA.

Hi,
Please provide logs of communication line when the device is offline.
Also provide a screenshot of the values when the device is offline.

Hi,

Does it work from another PC in the same network?
Please press F12 in a browser and provide logs (or screenshots) from the Console and Network tabs.

[Mikhail]

I can help you to create a formula for such channel if you need.

[Mikhail]

What is the OPC server you use?

[Mikhail]

Hi,

Please try Matrikon OPC Simulation server. Does it work?
Also try to browse the OPC server by this utility. What is the result?

[Mikhail]

The format of the WebSettings.xml file was changed. You should take the new one from the distributive.
You don’t need CommSettings.xml for the web app no more.

[Mikhail]

Also check CPU load of ScadaServerSvc.exe.

[Mikhail]

Hi,

Please open C:\SCADA\ScadaWeb\config\WebSettings.xml in a text editor and check CommSettings section. These are the connection parameters for the web app. Can you provide them here?
