Hello,
What error do you get when open http://localhost:your_port ?
Does the above help?

Hello,

First of all, check that AspNetCoreModuleV2 is installed as shown here.

Hi,

It can be a good idea. Please let us know if it helps to solve the issue.

If you provide screenshots from any OPC UA client that does what you need, it can help.

Hi,

Create a single channel of the Calculated/Output type. Set the Output formula to SetData() After making that settings it should be possible to change channel value by a user. This does not depend on the device.

If you need to set Modbus register according to a command, configure the Modbus template, and then create channels by a wizard.

> it is possible to create a Virtual Device
Yes. In this case, a device just helps to group channels. Calculations are defined by channels.

Hi,
It seems that we are close to understanding the cause.
If you restart the PC in usual way, do you get the same error?

[Mikhail]

Hi,
I’ve wrote down a note to increase the priority of this task.

> Is there a way for me to define what the event says?
The answer depends if you use Rapid SCADA 5 or 6. For version 6, set channel properties:
Input formula would be Cnl > 0 ? 0 : 1
Format is Off-On

[Mikhail]

May be the error occurs after the computer restart? And PostgreSQL has not started yet?

[Mikhail]

Hi,

1) The error is weird. It’s the first time when we faced this type of error.
What PostreSQL version do you use?

2) Probably, it just reconnects. The next time, if the error occurs, try stop and start SCADA-Serve without uploading the project.
Using pgAdmin simply try to connect to the database and open the data tables after the error occurs.

Hi Matt,
Thank you for the reminder.
Do you need an example that demonstrates how to create an HTML page that uses JS API to get data (like v5 custom page example)?

[Mikhail]

The OPC UA driver subscribes for data, and receives data in async mode when data comes from the OPC UA server. The driver does not send requests each time to read data.

> in facts it sends all the cycle data in one event type response.
Could you copy the example from the communication line log?
