Setting up OPC UA connection to a Siemens Sinumerik 840D control. I have the agent configured and can browse tags. I am wanting to understand some of the attributes that are not available to me.

Anyone have any experience with Siemens 840Dsl and ignition??

Did you ever get anywhere with this? We are looking to do some SINUMERIK integration. There are many variables that are accessible to the Siemens OPC-UA software that aren’t in PLC data blocks such as NCU information.

I guess this will have an MTConnect interface not PLC interface! (I may be wrong).

> Innorobix Automation developed an MTConnect module for Ignition that can be connected to multiple agents. The neat feature about this module is that it will dynamically create and sort the associated tags per agent and make them available in designer under providers. Feel free to reach out if you want to see a demo.

Is this as easy as configuring the softing uagate opc-ua server and connecting to a [third-party OPC-UA server](https://www.inductiveuniversity.com/videos/connecting-to-kepware-opc-ua/8.0)?
