Hi Ignition Team, I have been trying to connect Rockwell STUDIO 5000 with ignition to do some HMI design testing through OPC / UA. I have been unable to as it shows the status is faulted and the error message is. COM object method returns error code: 0x80040112; CLASS\_E\_NOTLICENSED (Class is not licensed for use) Could you please help me in resolving this. Thanks in advance ---

1. I am connecting to the OPC COM as I am following a video, the link is attached below. In the video it shows the status is connected. but not while I do it.

I am using in trial mode same as shown in above video's. Would be great help to know what's to be done. Thank you ---

RSLinx as included with RSLogix (RSLinx "Lite") does not permit connections from non-Rockwell software. You need an RSLinx licensed version to connect from Ignition. ---

Thank you for the clarification, any idea which version of RSLinx is suitable for 3rd party software's? Such as Igntion to connect through OPC/UA. ---

It would be FactoryTalk Linx (Formerly RSLinx Enterprise) for the OPC/UA functionality, IIRC. You probably want either the "Single Node" or "Gateway" license. You should probably talk to your Rockwell distributor (you will need to anyways, to get pricing). ---

Alright, thank you for the help. Much appreciated. I will have a chat with the distributor regarding the same.
