Rest API integration

[r1moore]

I have a script written in C# that makes a REST API call to collect weather data and works in a local environment. How do I integrate this script with Rapid SCADA? Specifically, I need to know where to apply it within the Admin app and how to add the results from the script as a view on the web server. Any detailed guidance or steps would be greatly appreciated.

write a simple driver where your code, when going somewhere for the weather, will give you data as channel values.

or if the code is very simple, try using it in scada scripts

[manjey73]

I wrote examples when the scada script takes data from a file, for example. without creating a driver

[r1moore]

I have the code in scada scripts currently but I am unsure how to call it from other tables.

Creating a driver seems like the best option. Check this article.
Otherwise, you could write data to a database, then read by Rapid SCADA.

I noticed in the driver documentation it says to use the Class Library template. Where can I find this?

In Visual Studio 2022 Community when create a new project.

I have created a custom driver and added it as a communication line in the Scada Admin application. I selected my custom driver in the Device Polling tab and ensured its description was displayed correctly. I uploaded the configurations but I am getting the following error in the communication line log: Error reading file [Comm]/[Log]/line003.log: File not found

What is causing this error?

[Mikhail]

Check ScadaComm.log for error. Probably the communication line is not started, therefore its log does not exist.

Where can I find an example of a custom driver method for writing data to an input channel?

[Mikhail]

A driver does not write data to input channels directly. It writes data to a tag. Communicator binds tags to channels. Data sources send tag data to Server according to the bindings. Use DrvSimulator as an example.

It’s possible to create a client from a driver code and interact with the Server service. But it’s not as designed.
