When a device is disconnected, channel status = 0. You should also store status in the database, or use status to convert values to NULL if status is zero.

Hi,

There are 2 independent tasks:
1. Get data from OPC DA.
2. Provide data as OPC UA. Rapid SCADA 6 is needed for this.

To solve the 1st task, use usual configuring sequence, as written above. In case of errors, please provide screenshots of the settings and logs.

After the 1st task is done, ask about the 2nd,

Hi,

Do you mean displaying data on a map permanently? Could you draw an example?

[Mikhail]

Hello,
In the connection options of the Communicator B you should specify the Server A.
It would be more efficient if you provide screenshots of your settings.

Hello,
API provides access to channel data by channel numbers. Channel names are not unique, so cannot be used to get data.

Getting channel data using REST API by some unique string codes can be a good idea for the future improvements. Currently, you need an internal dictionary that provides channel number by its name or code.

Hello,
I think, you need 4 instances in the project:
– Default
– Remote1
– Remote2
– Remote3

The instances are declared in the project, and deployed on different machines.

Also check in log files that data queues of the module do not overflow.

In Rapid SCADA all data uses UTC timestamps. Some databases (like PostgreSQL) have special data type to work with timezone, some databases don’t have such data type.
If actual timestamps always differs by timezone offset, it’s OK and can be corrected in the SQL request.

Hi,

I recommend use the same Tag Code and Topic parameters.
You don’t need to create commands under the Command node.
If a subscription is created and not read only, a value can be published.

I suggest trying broker.mqtt-dashboard.com for testing.

Could you tell what is “BBDD”?
What is the time zone?

[Mikhail]

Can’t find a screenshot where the Options node is selected.

[Mikhail]

Hello,

Could you add a screenshots of Device 4 Properties – Options?
If you try the same on public broker broker.mqtt-dashboard.com, does it work or not?

[Mikhail]

Hello,

Currently, the MQTT driver doesn’t support strings. It’s possible to implement in the future.
Strings are supported by OPC UA driver, for example.

If device communication was OK, and then the device become unavailable, the device data in Communicator should be changed to ---. If not, let me know and provide communication line log.
