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?

[Mikhail]

What Windows language do you use?

[Mikhail]

Hi,

Your issue is similar to this. But a user didn’t notify about the result. Please try the advice and write here whether it helps or not.
It’s easy to change culture, but it’s strange that Administrator stops. Could you provide more info about it?

To send commands every 5 seconds by Automatic Control Module, you need to create a trigger fires on data change, and create an input channel that changes every 5 seconds.

[Mikhail]

Automatic Control Module sends commands via output channels or directly to a device.
Do you really need to change input channels by commands?

[Mikhail]

Hi,

Is it possible to provide a log of communication where we can see what packets were sent and received and timings?
Do you send commands by Rapid SCADA?
