will I be able to publish scada data to a standalone mqtt broker, so that other application can subscribe it to get the data ?
can you mention the steps to enable and communicate Mqtt Publisher

Yes, you can. To get more info about configuring that driver, please create a new topic related to MQTT Publisher.

[Mikhail]

It’s possible to send a command via the Administrator app, but I can’t find information about the required command format, because that version of the driver is too old and outdated.

is it possible for me to use a cloud server instead?

Rapid SCADA works well on a cloud server.

Note. Recently Rapid 5 was removed from the download page. Use the 6th version which is more secure.

To display strings in the web app, set channel data type to Unicode string.

[Mikhail]

Could you provide screenshots?
The driver works with numbers and 4-character strings. Long strings currently not supported by the driver.

Hi,
Thank you for the info.
In addition, try changing the service user as shown here (ScadaComm6 service). There is a chance to run Communicator as a service.

OPC DA (Classic) may be unpredictable. It’s a bad technology. You should use OPC UA instead.
The checkbox is in the screenshot https://ibb.co/wzjYYrN

[Mikhail]

The proper way is upgrading Rapid SCADA to the version 6 and after that solve export questions.

[Mikhail]

Command type of the output channel should be binary.

[Mikhail]

In the screenshots, the number of the output channel is 201 while in the configuration form 631 is specified, which is wrong. It should be 201.

Name Constraints
Class names and namespaces are important. Locations of the classes’ files are about code style.

Module Placement: \ScadaWeb\wwwroot\plugins

Plugins include DLL which is located in \ScadaWeb\ and static files in \ScadaWeb\wwwroot\plugins

It’s possible that received values are rounded by the driver. I’m sure sure. You should get channel data as a byte array and play with it.

[Mikhail]

Do you use MQTT or Modbus protocol?
Could you make a screenshot of a device data page from Communicator?

[Mikhail]

Hi,

Now as my data is changing frequently instead of using GET call, is there data streaming API call available by which my application will read the data as soon as it change ?

Try using DrvMqttPublisher driver which publish data on change by MQTT.

[Mikhail]

Do you mean the page in the image4 in the drive I shared? And what should I put in the tag?

Yes, image4.
