Hi John,

I researched for this, and I have’t found any free solution. We can develop such driver as a custom development by a contract.

You have 2 options:
1. Install on RTU VM only Communicator which connects to the Server app of the main VM.
2. Install on RTU VM full Rapid SCADA and use Rapid Gate.

about a key that would be needed to use the Rapid Gate. How would this be obtained?

Buy permanent key or use free trial

[Mikhail]

Seems like hardware problem. What USB-COM converter do you use?

[Mikhail]

Hi,

We have Spanish section in the documentation. It needs to be updated. To work with it, you should register GitHub, fork the repository, make your changes and create a pull request to include them into the project.

Hi,

Use the above sequence

[Mikhail]

May be other application uses the same port COM4.

[Mikhail]

The log says that there are problems with a converter:

2019-06-17 17:00:23 Open serial port COM4
2019-06-17 17:00:23 Error executing the communication channel actions before session with a device: Error opening serial port: Access to the port ‘COM4’ is denied.

Hi,

Rapid SCADA works as TCP client, not TCP server. It connects to a PLC which is TCP server and PLC keeps port 502 open.

Hi,

1. Please clarify the question.

2. Do you mean using real devices or simulators?
There are 2 videos where shown how to simulate a Modbus RTU and OPC connected device.
It would be better if you provide a diagram of your system.

[Mikhail]

Hi,

How the devices are physically connected to Rapid SCADA server?

[Mikhail]

Hi,
I’ve sent an email.

[Mikhail]

after about 4 hours a first queue overflow alarm is coming out

A long time needed for exceeding the queue size means that simple increasing the queue size doesn’t solve the issue.

[Mikhail]

you should have my email where to write your offer for remote

Please send email again to let me identify you correctly ))
Your description is clear, but watching the process is more efficient.

[Mikhail]

Hi,

Likely the queue size is exceeded because of the error executing the request. What is the full situation in logs currently?
I could connect to your machine remotely and research for the cause, but this service is out of free support.

[Mikhail]

This is strange, because there is no column named “Infinity” in your SQL requests. Do you have any idea where you can mention “Infinity”?

Also ExportEvents tag contains false that means that “Error export events” should not be printed in any case.

May be another configuration is running?
