Hello,

I would like to display (and possibly edit) the Read-Only setting of OPC UA servers in Perspective.

 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/b/dbb4792c37952ea6c9a24b0da722027fa44b2ab7.png)

I haven’t been able to find a corresponding tag in the **System** tag provider or any system function that would give me this information. Because of that, I believe my only option is to use the Gateway REST API. However, I’ve run into some HTTPS-related issues while trying to use it.

Before I spend more time troubleshooting that, I’d like to make sure there isn’t another way to access this setting. Did I miss something, or is the REST API my best option here?

I think the REST API may be your only option.

This is likely also possible (though unsupported) via the configuration manager reached by the gateway context.

I found the following approach:

```python
path = '/usr/local/bin/ignition/data/config/resources/core/ignition/opc-connection/LAB/config.json'
system.file.readFileAsString(path)

```

This works for reading the configuration, but it doesn’t seem like the right way to modify it. Or is there any way to trigger a configuration reload?

@pturmel which configuration manager are you referring to? Could you point me in the right direction or provide some resources where I can find more information?

This one: [getConfigurationManager()](https://files.inductiveautomation.com/sdk/javadoc/ignition83/8.3.0/com/inductiveautomation/ignition/gateway/model/GatewayContext.html#getConfigurationManager())

I recommend using my Integration Toolkit's `system.util.toolkitCtx()` to get started.

You are in SDK territory, so not officially supported. If you need a supported approach, stick with the exposed OpenAPI methods.

Hopefully as soon as 8.3.5, there's going to be a `system.config` scripting namespace that gives you general purpose CRUD across all resource types, plus a `system.config.requestScan`.

There's a REST API endpoint to do so as well.

The right thing to do is to get your rest API access working.
